PRODUCT SELECTION

Consult BriskHeat factory for product selection and application engineering support.

RECEIPT & STORAGE

Receipt

 Compare the materials against the shipping bill to verify receipt of proper materials.

 Inspect heating cable and components for transit damage. Insulation resistance tests on each spool of cable are recommended.

 If design documents (line lists or per circuit bills of material) exists, check the received materials against the lists to verify of all

needed materials. If no design documents exists, keep a receipt log of all materials received.

Storage

Cables and system components should be stored in a clean, dry area. The equipment should be protected from mechanical damage

during storage. The storage temperature range is (-40°F to 140°F) -40°C to 60°C.

INSTALLATION

While there are many acceptable ways of installing BriskHeat’s electric heating equipment, certain actions can be dangerous to

personnel and your installations. Please take care to avoid the following problems:

 Do not twist the bus wires together at either end of the heating

cable. Each of these wires has a voltage or neutral applied to it;

twisting them together will cause a short circuit.

 Insulate black polymer surrounding bus wires. The black compound

extruded around the bus wires is electrically conductive and should

be treated as a conductor.

 All electrical connections in the system should be sealed against

moisture. To prevent electrical arcing and fire hazard, all cable

connections and electrical wiring connections should be sealed

against moisture. This includes the use of proper cable sealing kits

and the moisture proofing of all wire connections.

 Do not expose heating cables to temperatures above their

maximum ratings. Higher temperatures can greatly shorten the life of

a heating cable.

 Immediately replace any damaged heating cable or components.

Failure to replace any damaged components ( heating cable,

components, or thermal insulation) will result in system failure.

 Classified areas (explosive dust or gases) require the use of special

electrical components. Any area having explosive gases (such as

chemical / petrochemical installations) or explosive dusts (such as

coal handling or graineries) require special cable, connection

components and control components that are approved for use in

these areas. Installation of non-approved products can result in fires

or explosions.

 Installation on plastic pipe requires special considerations in

selections & installation.

GENERAL INFORMATION

This manual is designed for use with BriskHeat’s self-regulating heater products. For applications not specifically addressed, please

contact your local representative.

How Heating Systems Work

An electric heating cable system uses the electric heating cable to replace the heat that is

lost through the thermal insulation system. Replacing the lost heat allows the pipe and

product inside the pipe to be kept at a constant temperature. This will keep water from

freezing and bursting a pipe, or a liquid from setting up and plugging the pipe. Simple

systems may turn the entire system on with a contactor or switch, while others will use a

thermostat with each heating cable to control the temperature.

Self Regulating Heating Cable

Scheduling

The installation of the electric heat tracing needs to be coordinated with the piping, insulation, electrical and instrument groups. It should

begin only after the majority of mechanical construction is complete. Pressure testing of the pipe and installation of the instruments

should be complete prior to the start of the heating cable installation.

Pre-Installation Check

Walk the piping system and plan the routing of the heating cable. Use this check to verify completion of instrumentation and mechanical

work. All coatings (paint, etc.) must be dry before attempting the heating cable installation. Minimum installation temperature -40°F

(-40°C)

Heater Handling

 Use a reel holder to roll out the heating cable.

 Keep the cable strung loosely, but close to the pipe being traced. This will avoid interference with supports and other equipment.

 Leave an extra 305-457mm (12-18”) of heating cable at all power connections, tee splices and end seal connections to facilitate

easy working of the connections.

 ADDITIONAL HEATING CABLE IS REQUIRED ON VALVES, PIPE SUPPORTS AND OTHER EQUIMENT. See the installation

detail section for exact lengths and method of installation.

 When handling the heating cable, avoid pulling it over or installing against sharp edges.

 Do not kink or crush the cable, including walking on it or driving over it with equipment.

 Do not exceed minimum bending radius of 0.5” (12mm) at 68°F (20°C) during installation. Colder temperatures will increase the

minimum bend radius. Use caution to avoid exceeding a safe bend radius during cold temperature installations.

Heating Cable Location

The heating cable may be installed in either straight runs or spiraled around the pipe. Spiraling is generally used when a limited number

of cable types are available.

Straight Tracing

When straight tracing is used, install the heating cable on the lower quadrant of the pipe. This helps prevent physical damage to the

heating cable from falling objects and being walked on, and promotes optional thermal transfer to materials inside the pipe.

Alternate Locations

Install heater cable at

the 4 or 8 o’clock positions

120°

Self Regulating Heating Cable

Attachment

For regular installations, the heating cable may be attached with fiberglass tape. Plastic wire ties may also be used provided the plastic

has a maximum temperature rating equal to or better than the system requirements. The cable should fit snugly against the pipe and be

secured at one 305mm (12”) intervals, as shown in Figure 4.

Notes:

1. To prevent possible damage to the heating cable, do not fasten with metal straps, wire, vinyl electrical tape or duct tape.

2. Aluminum foil tape should only be used if specified by design. The foil is most often used on plastic pipe to offset the insulate effect

of the plastic. See Figure 5 above.

Cutting the Heating Cable

Do not cut the cable until it is attached to the pipe. Confirm the allowances for terminations, connections and heat sinks (valves,

support, etc.) before cutting the cable. Heating cable power is not affected by cutting to length. Protect all heating cable ends from

moisture or mechanical damage if exposed for long periods of time.

Installation Details

Heating cables should be applied in a manner to facilitate the easy removal of valves and small in-line devices without the removal of

excessive thermal insulation or having to cut the heating cable. The best way to accomplish this is to loop the cable. The amount of

heating cable installed on each valve, hanger, etc. varies with the pipe size and type of device. For installation and application

assistance, contact BriskHeat factory.

Spiraling

Spiraling increases the length of heating cable installed per foot of pipe. For spiraling application assistance, contact BriskHeat

factory.

SYSTEM COMPONENTS

Only BriskHeat’s approved termination, connection and splice kits should be used. Failure to do so will void warranties and agency

approvals. Installation instructions in each component kit should be followed regarding heating cable preparation and assembly. Make

end seals (terminations) and splice connections before making the power connections. It is recommended that all heating cables be

tagged as they are installed with a discrete circuit number. This will facilitate identification, components needed and electrical wiring

during later phases of the installation. Power connection kits utilize an adapter plate kit for installation on instrument tubing and tanks.

Installation instructions for mounting are included in each kit.

Note: Heating cable power connections and end seals are required for each heating cable. Heating cable splices, tees, and

thermostats are used as needed.

Self Regulating Heating Cable

Marking

Install “Electric Trace” signs on alternate sides of the piping at regular intervals, as a warning to maintenance personnel. Permanently mark the outside of the insulation

lagging with the location of heating cable components. This will facilitate maintenance in the event of a problem.

THERMOSTATS & SENSORS

Temperature sensitive applications will require the use of a thermostatic control. Selection of the proper thermostat must consider voltage and amperage ratings of the device

as well as the suitability of housing for the environment (explosion proof, rain tight, corrosion resistance, etc.). Thermostat housing should be mounted as close as possible to

the power connection kit. It may be attached to the power connection kit provided code requirements are met with regard to conduit connections seals, etc. To sense the

coolest air temperature, ambient (air sensing) thermostats should be mounted in the shade when possible. When using pipe-sensing thermostats, the bulb (sensor) should be

mounted on the opposite side of the pipe from the heater, or as far away as is practical. This will allow the thermostat to sense the actual pipe temperature and not be

influenced by the heater temperature. Mount the bulb at least three (3) feet from the closest heat sink if possible.

Moisture inside the enclosure will cause both corrosion and electrical shorting problems. The potential for this type of problem can be greatly reduced by:

 Proper sealing of all enclosures openings.

 Keeping enclosure cover closed and secured as mush as possible during installation sequence.

 Proper closing and sealing of the cover to prevent leaking into the housing.

 Use of a moisture proofing/electrical spray (aerosol) sealant on thermostat and electrical connections (including all metal parts) at completion of installation.

 Connection and use of space heater if thermostat is so equipped. Do not de-energize space heater during summer months.

ELECTRICAL REQUIREMENTS

Voltage Rating

Verify that the heating cable voltage rating is suitable for the service being used. 240 volt rated cables may be used from 208 to 277 volts, with an accompanying change in

power output.

THERMAL INSULATION

Pre-Installation Checks

Inspect the heating cable and components for correct installation and possible damage. In particular, verify that:

 The proper extra amount of heating cable has been installed at each valve, flange, pipe support, etc. and that it is free from physical nicks, tears or gouging. Additional

cable beyond the specified amount at a heat sink is not a problem due to the self-regulation effect of the heating cable.

 Connections, splices and end seals are correctly installed, including cable seals at power connection enclosures.

 Ensure insulation is properly rated fir the maximum edxposure temperature of the heated system.

Installation

Check the thermal insulation type and thickness against the design criteria. Changes in insulation type or thickness may require a different wattage heating cable. Verify that

all pipe work, including wall penetrations, fittings, etc. has been completely insulated.

Check the system to verify that:

 Insulation is not wet from rainfall prior to the application of waterproofing.

 Lap joints on vertical piping are properly overlapped - higher piece lapped over the top of lower piece.

 Band seals are used at lap joints to prevent the ingress of water.

 All penetrations of lagging (valve stems, hanger rods, etc.) are properly water proofed.

 Irregular shaped items (i.e. pumps, etc.) are properly waterproofed.

To minimize potential damage to the heating cable, install the insulation as soon as possible. It is recommended that another insulation resistance (megger) test be done after

the insulation has been installed to verify that the heating cable was not damaged during the insulation installation.

Self Regulating Heating Cable

Ground Fault Protection

Ground fault circuit breakers are required on all heater constructions per the National Electric Code. Typically, 30ma trip devices are

required due to the capacitive leakage of the heating cable construction.

Waterproofing

Moisture penetration of the electrical system is the single largest source of problems in a heating cable system installation. Therefore,

particular care must be given to the proper sealing of all electrical connections and splices. Heating cable sealing kits will provide a

proper seal for the heating cable itself, when used per kit instructions. All other electrical connections (heater to power wiring,

thermostat connections, panel and breaker connections, etc.) should be sealed or moisture proofed in some fashion. Either mastic

shrink tube or an aerosol electrical insulative sealant should be used on all connections to reduce any moisture penetration. The

sealant will also reduce the potential for corrosion on exposed metal parts.

TESTING

Recommendations

Electrical tests are recommended at specific points in the receipt and installation of the heating cable. This periodical testing is

designed to prevent the expenditure of wasted labor in the event of damage to the product. Installation costs of the cable and thermal

insulation are much greater that the heating cable. Quick identification of any heating cable damage is the most economic approach to

an installation. An insulation resistance test is recommended at the following point of the installation process:

 UPON RECEIPT of the heating cable

 BEFORE thermal INSULATION installation

 IMMEDIATELY AFTER thermal insulation installation

 As part of a PERIODIC MAINTENANCE program

Procedure

The insulation resistance test is used to check for damage to extruded jackets. Connections for the megger are made as shown in

Figures 18 & 19.

Note: Test should use at least a 500 VDC megger. Do not use a megger with an excess of 2500 VDC. Minimum acceptable readings

should be 20 megohms per circuit, regardless of length.

Figure 19

A record should be kept of the readings taken from the time the cable is first installed on the pipe. A history of the insulation resistance

reading can be helpful in spotting moisture ingress into the electrical system (by seeing a gradual decline in the insulation resistance or

physical damage to the heating cable (sharp decline in the insulation resistance). A sample record for this is shown in Figure 20. (See

following page)

Periodic Inspection Record Form

The Periodic Inspection record Form may be used in one of two ways:

1. One sheet per circuit - The results of periodic tests of a single circuit are posted in vertical columns, beginning on the left and

working toward the right. This allows easy comparison of test values for up to seven test sequences on an individual circuit.

2. One circuit per column - Test data for a single test sequence on as many as seven circuits can be recorded on a single sheet.

Freeze Protection Circuits -

Perform these checks as season requiring use approaches.

Temperature Maintenance Circuits -

Perform these checks at least twice per year.

START-UP

Heat-up Time

Heat-up capacity (the ability to heat the pipe and it’s contents rapidly) is not normally designed into the system. Cold start-ups should

allow adequate time for the pipe to come up to temperature.

Diversity Factor

If the electrical supply capability is limited, then a diversity factor may be used in a cold start situation (trying to start the entire system up

in very cold weather). This is accomplished by staggering the initial turn on of the heating cable circuits to allow the inrush currents to

occur in a sequential fashion rather than all at once.

OPERATION & MAINTENANCE

System Design, Installation & Documentation

The heating cable system must be properly designed, installed and documented. This documentation should at least include line lists and

location identification documentation. As built installation drawings provided the optimum maintenance tool. Test records should also be

considered as part of the system documentation requirements. See Figure 20 & 21.

Preventive Maintenance

A preventive maintenance program is needed which will encompass both visual and electrical checks of the system. These should be

done not only before initial operation of the system, but also on a scheduled basis. The checks should also be done after any

maintenance has been performed.

Visual Inspections

 Thermal insulation - check weatherproofing for damage, missing seals, cracks or gaps in caulking and mastic coatings, damaged or

missing lagging. When damage does exist, the insulation will need to be repaired or replaced, and then resealed. WET INSULATION

HAS POOR INSULATING PROPERTIES, THEREFORE THE INSULATION MUST BE KEPT DRY. If insulation has been damaged,

check the heating cable for damage - replace the damaged section.

 Inspect junction boxes, connection boxes and thermostats for corrosion, moisture or foreign matter.

 Tightness of electrical connections, proper electrical insulation of heating cable wires, adequacy of moisture seal on electrical

connections and that a minimum of one (1) inch of electrically insulated heater extends above the grounding connection. No strands

of the ground braid should extend above this connection.

 Check all thermostats or sensor capillary leads to verify they are tied back and shielded from physical damage.

 Verify all enclosure, connection box, etc. covers are properly closed and that the thermostat is switching off and on by measuring

current flow in the circuit when the unit switches on. Reset the knob to the proper temperature after completion of the test.

Frequency

Inspections should be made prior to the start of the freeze season on freeze protection systems. Process maintenance systems should

be checked on a frequent base, at least twice a year.

Personnel Training

Qualified maintenance personnel must be used to maintain the system. It is recommended that periodic training programs be utilized to

assist in keeping maintenance personnel up to date on equipment and procedures.

Maintenance

The heating cables will not require any maintenance. Mechanical temperature controls should be sprayed with a moisture repellent/

corrosion inhibitor once a year on all metal parts.

Piping Repairs

Disconnect the electrical connection for the heating cable and protect it from mechanical or thermal damage during the repair. Check the

heating cable installation after the repairs per established procedures. Replace and water seal the thermal insulation system.

Self Regulating Heating Cable

DAMAGED PRODUCTS

Do not attempt to repair a damaged heating cable - replace the entire section. Fault currents will often destroy the bus wire / core ma-

terial interface between the damaged portion and the voltage supply end of the circuit.

Replace the damaged heating cable immediately. Moisture migration into the good section of the heating cable may cause electrical

shorting in that cable after repair of the damaged section.

Any product exposed to fire or flame should be removed from service immediately and replaced. Further fire damage could result if

energized.

TROUBLESHOOTING GUIDE

PROBABLE CAUSE CORRECTION

A. Circuit Breaker

Trips

(Standard)

1. Circuit breaker undersized 1, 2, 3. Re-establish what the current loads are going to be

and resize the breakers.*

2. Circuit oversized

3. Start-up at too low temp.

4. Defective circuit breaker 4. Replace circuit breaker.

5. Connection and/or splices may be

shorting out.

5, 6. Locate and repair incorrect connections, splices, or

damaged sections of heating cable.

** Megger per installation instructions.

6. Physical damage to the heating

cable may be causing a short.

7. Wires connected at end seal. 7. Disconnect wires and perform a current check for

possible other damage.

B. Circuit Breaker

Trips (Ground

Leakage Type)

1. All of section A. 1. All of section A.

2. Excessive moisture in connection

boxes or splices.

2. Dry out and re-seal connections and splices. Megger

per Installation Instructions (20 megohms min.) Work

on connections outside the thermal insulation first,

going to the below insulation connections and seals

after the others have been eliminated.

3. Nick or cut in heater or power feed

wire with moisture present.

3. Locate and repair or replace damaged heating cable

or power wire.**

SYMPTOMS

* Check to see if existing power wire sizing is compatible with larger sized breakers.

** To locate shorting problems, follow these steps:

1. Visually inspect the power connections and splices that are outside of the thermal insulation for proper installation.

2. Check around the valves, pumps, and any area where there may have been maintenance work done, for visual indications of

damage.

3. Look for crushed or damaged insulation lagging along the pipe.

4. Inspect heating cable splices under the thermal insulation.

5. If you have not located the problem by now, you will have to isolate one section of the heating cable at a time until you

determine the general area of damage. First, isolate by disconnecting any tees or splices then remove insulation from that area

until the specific damage is found. For long runs of cable, it may be necessary to cut the cable in half to isolate the shorted

section.

Self Regulating Heating Cable

SYMPTOMS PROBABLE CAUSE CORRECTION

Power output is zero or

lower than rated.

***

1. Low or no input voltage.

2. Circuit is shorter than design shows.

a. Splices or tees may not have been

connected.

b. Heating cable may have been

severed.

3. Improper crimping causing a high resistance

connection.

4. Control thermostat is wired in the opened

position.

5. Pipe is at an elevated temperature.

6. Heating cable has been exposed to

excessive moisture.

7. Heating cable has been exposed to

excessive temperatures.

1. Repair electrical supply lines and equipment.

2. Check routing and length of heating cable

(use “as-builts”), and recalculate power

requirements.

a. Connect and recheck the power.

b. Locate and repair the damaged heating

cable. Recheck the power.

3. Re-crimp using correct procedure.

4. Rewire in the normally closed position.

5. Check pipe temperature and recalculate the

output.***

6,7. Replace the heating cable.

Power output appears

correct but pipe

temperatures are

below design value.

1. Insulation is wet.

2. Insufficient heating cable was used on

valves, supports, and other heat sinks.

3. Thermostat was set incorrectly.

4. There are thermal design inconsistencies.

1. Remove and replace with dry insulation and

insure proper weatherproofing.

2. Splice in additional heating cable but do not

go over maximum circuit length.

3. Reset the thermostat.

4. Check with the local or factory representatives

for design conditions. Modify as

recommended.

*** The power output on lower resistance heating cables is temperature sensitive and requires a special procedure to determine it’s

value.

1. Check the pipe temperature under the thermal insulation.

2. Allow heating cable to stabilize for 10 minutes and then measure the current.

3. Calculate the power (watts / ft.) of the heating cable by multiplying the current by the input voltage and dividing by the actual

circuit length

4. Compare this measured value to the power output curves for the heating cable at the measured pipe temperature. If the

heating cable’s actual output is substantially below the theoretical output, the bus wire interface with the core has been

damaged by the fault current and the cable must be replaced. This is not a highly accurate method of analysis, so use

discretion in comparing theoretical and actual values.

INSTALACIÓN

INFORMACIÓN GENERAL

Este manual está destinado a su uso con los productos de la línea de calefactores autorregulados de BriskHeat. Para aplicaciones que

no estén tratadas específicamente, contacte con su representante local.

Cómo funcionan los sistemas de calefacción

Un sistema de cable calefactor eléctrico utiliza el cable para reemplazar el calor que se

pierde a través del sistema de aislamiento térmico. El reemplazo del calor perdido permite

que la tubería y el producto que está dentro de ella se mantengan a una temperature

constante. Esto evitará que el agua se congele y haga estallar una tubería, o que un

líquido se solidifique y la tapone. En los sistemas simples puede energizarse todo el

sistema con un contactor o un interruptor, mientras que otros utilizan un termostato con

cada cable calefactor para controlar la temperatura.

SELECCIÓN DE PRODUCTOS

Por todo lo relativo a selección de productos y asistencia en ingeniería de aplicaciones, consulte con la fábrica de BriskHeat.

RECEPCIÓN Y ALMACENAMIENTO

Recepción

 Compare los materiales con los indicados en el certificado de embarque para verificar que se recibieron los materiales correctos.

 Inspeccione el cable calefactor y los componentes para ver si hubo daños en el tránsito. Se recomienda realizar pruebas de

resistencia de aislamiento en cada carrete de cable.

 Si existen documentos de diseño (listas de líneas o listas de materiales por circuito), revise los materiales recibidos en

comparación con los indicados en las listas para verificar que se disponga de todos los que sean necesarios. Si no existen

documentos de diseño, mantenga un registro de recepción de los materiales recibidos.

Almacenamiento

Los cables y los componentes del sistema deben almacenarse en un lugar limpio y seco. El equipo debe protegerse de los daños

mecánicos durante el almacenamiento. El rango de temperatura de almacenamiento es -40 °F a 140 °F (-40 °C a 60 °C).

Tubería

Si bien hay muchas maneras aceptables de instalar los equipos de calefacción eléctrica de BriskHeat, algunas acciones pueden ser

peligrosas para el personal y para sus instalaciones. Procure evitar los siguientes problemas:

 No retuerza entre sí los cables del bus de alimentación en un

extremo del cable calefactor. Cada uno de estos cables tiene una

tensión aplicada o está conectado al neutro; por lo tanto, al

retorcerlos entre sí se causará un cortocircuito.

 Aísle el polímero negro que rodea a los cables del bus. El

compuesto negro extruido alrededor de los cables del bus es

eléctricamente conductor, y debe tratárselo como tal.

 Todas las conexiones eléctricas del sistema deben sellarse contra la

humedad. Para prevenir la formación de arcos eléctricos y el riesgo

de incendio, todas las conexiones de cables y conexionado eléctrico

deben sellarse contra la humedad. Esto incluye el uso de kits de

sellado de cables apropiados y la impermeabilización de todas las

conexiones de cables.

 No exponga los cables calefactores a temperaturas que superen su

especificación máxima. Las temperaturas muy elevadas pueden

abreviar considerablemente la vida útil de un cable calefactor.

 Reemplace de inmediato todo cable calefactor o componente

dañado. Si no se reemplazan los componentes dañados (cable

calefactor, componentes o aislamiento térmico) se producirá una

falla del sistema.

 Las áreas clasificadas (con polvo o gases explosivos) requieren el

uso de components eléctricos especiales. Toda área en la que haya

gases explosivos (como en instalaciones químicas o petroquímicas)

o polvos explosivos (como en instalaciones de manejo de carbon o

graneros) requiere cables, componentes de conexión y

componentes de control especiales, que estén aprobados para su

empleo en esos lugares. La instalación de productos no aprobados

puede dar como resultado incendios o explosiones.

 La instalación de tuberías plásticas requiere consideraciones

especiales en cuanto a selecciones y características de instalación.

ADVERTENCIA

Cable calefactor autorregulado

Programación

La instalación de la aplicación de calor eléctrica debe coordinarse con los grupos de tuberías, aislamiento, electricidad e

instrumentación. Debe comenzar una vez que haya finalizado la mayor parte de la construcción mecánica. Las pruebas de presión de

las tuberías y la instalación de los instrumentos deben haber finalizado antes del comienzo de la instalación de los cables calefactores.

Verificación previa a la instalación

Recorra el sistema de tuberías y planifique el encaminamiento del cable calefactor. Utilice esta inspección para verificar que se hayan

cumplimentado los trabajos de instrumentación y mecánicos. Todos los recubrimientos (pintura, etc.) deben estar secos antes de

intentar la instalación del cable calefactor. La temperatura mínima para la instalación es -40 ºF (-40 ºC).

Manejo del calefactor

 Utilice un portacarrete para desenrollar el cable calefactor.

 Mantenga el cable tendido flojamente, pero cerca de la tubería a la que se va a aplicar calor. Esto evitará la interferencia con los

soportes y otros equipos.

 Deje una longitud extra de 305-457 mm (12-18”) de cable calefactor en todas las conexiones de alimentación eléctrica, empalmes

T y conexiones de sellado extremo, para facilitar el trabajo de las conexiones.

 SE REQUIERE CABLE CALEFACTOR ADICIONAL EN VÁLVULAS, SOPORTES DE TUBERÍA Y OTROS EQUIPOS. Vea las

longitudes exactas y el método de instalación en la sección de detalles de instalación.

 Al manejar el cable calefactor, evite arrastrarlo o instalarlo sobre bordes aguzados.

 No retuerza ni aplaste el cable, como por ejemplo caminando o pasando con equipos sobre él.

 No aplique radios de doblado menores de 0.5" (12 mm) a 68 ºF (20 ºC) durante la instalación. Con temperaturas menores, el radio

de doblado mínimo aumenta. Tenga cuidado para no aplicar radios de doblado menores que el valor seguro en instalaciones

realizadas a bajas temperaturas.

Ubicación del cable calefactor

El cable calefactor puede instalarse en tramos rectos o tenderse en espiral alrededor de la tubería. El tendido en espiral se utiliza por

lo general cuando se dispone de una cantidad limitada de tipos de cable.

Aplicación de calor recta

Cuando utilice la aplicación de calor recta, instale el cable calefactor en el cuadrante inferior de la tubería. Esto ayuda a evitar daños

físicos al cable calefactor causados por objetos que caen o por que se camine encima del cable, y favorece la transferencia de calor

opcional a los materiales que están dentro de la tubería.

Ubicaciones alternativas

Instale el cable calefactor en la

posición de la 'hora 4' o la 'hora 8'.

Fijación

En instalaciones comunes, el cable calefactor puede fijarse con cinta de fibra de vidrio. También pueden utilizarse sujetacables

plásticos, siempre que el plástico tenga una especificación de temperatura máxima igual o mejor que los requisitos del sistema. El

cable debe ajustarse bien contra la tubería y asegurarse a intervalos de 305 mm (12"), como se muestra en la Figura 4.

Notas:

1. Para prevenir posibles daños al cable calefactor, no lo sujete con fajas metálicas, alambre, cinta aislante eléctrica vinílica ni cinta

adhesiva para conductos.

2. Solo debe usarse cinta de papel de aluminio si está especificado en el diseño. El papel de aluminio se usa más frecuentemente en

tuberías plásticas, para compensar el efecto de aislamiento del plástico. Vea la Figura 5 arriba.

Corte del cable calefactor

No corte el cable hasta que esté fijado a la tubería. Confirme las tolerancias de las terminaciones, conexiones y disipadores de calor

(válvulas, soportes, etc.) antes de cortar el cable. La potencia del cable calefactor no es afectada por el corte de su longitud. Proteja

los extremos de los cables calefactores de la humedad y del daño mecánico si van a estar expuestos durante períodos prolongados.

Detalles de instalación

Los cables calefactores deben aplicarse de manera de facilitar la extracción de válvulas y dispositivos pequeños en línea sin tener que

extraer demasiado aislamiento térmico ni cortar el cable calefactor. La mejor manera de lograr esto es hacer un lazo con el cable. La

cantidad de cable calefactor instalada en cada válvula, soporte colgante, etc. varía con el tamaño de la tubería y el tipo de dispositivo.

Para obtener ayuda en la instalación y la aplicación, contacte con la fábrica de BriskHeat.

Aplicación en espiral

La aplicación en espiral aumenta la longitud de cable instalada por cada pie de tubería. Para obtener ayuda en la aplicación en espiral,

contacte con la fábrica de BriskHeat.
