2-1 Models Covered in This Manual
This manual lists installation, operation, and maintenance instructions for the hot oil portable
temperature control unit.
Model numbers are listed on the serial tag. A model number followed by Q indicates a specially
constructed unit, and not all information in this manual may apply. Make sure that you know the
model number, serial number, and operating voltage of your unit if you contact us.
2-2 General Description
Your hot oil temperature control unit circulates thermal transfer-type oil through your
process and to precisely, automatically, and reliably maintain it at a temperature you can select.
The operating range of your temperature control unit is from 100°F to 550°F (38°C to 288°C).
The unit is best suited for use with True Therm™ Heat Transfer Fluid. A recommended list of
commercially available heat transfer fluids can be obtained through customer service.
Rapid recirculation of the relatively small amount of fluid provides a close and uniform
temperature relationship between the TO PROCESS and FROM PROCESS lines. This does, of
course, depend on the configuration of your process, and any restrictions within the mold.
This recirculation, combined with the immersion heater and optional cooling capability, gives
fast and accurate response to bring the fluid up to temperature, or to changes in the settings
when needed.
Performance is assured through matching the unique controllers to the high temperature system.
The two systems are fully integrated to achieve accurate control, along with efficient use of
water and electricity.

3-1 Feature Descriptions
Immersion Heaters
The fluid is heated by the specially designed three-phase low watt density electrical immersion
heater, and regulated by the controller. The standard heater has a steel sheath for low watt
density and good heat transfer.
These models can be supplied with 6, 12, 18, 24 kW low watt density immersion heaters,
depending upon the heating needs of the process. The 18 and 24 kW models are built to provide
full or partial heat as required by the process and determined by the controller, to provide more
precise control.
Heater Tank
The M features a single pass heater tank. The tank is designed to maintain an optimum balance
of fluid velocity versus watt density, and turbulence for excellent heat transfer, and minimal
pressure drop. The high fluid velocity will greatly prolong the life of the heater and fluid.

Pump
The pump is a mechanical seal, positive displacement pump. It features a nearly maintenance
free design, and was selected after extensive testing to provide superior performance, flexibility
and low maintenance. It is well suited for use with a variety of commercially available heat
transfer fluids. The pump has only two internal moving parts, and a specially designed seal to
give years of trouble free service, even at high temperatures. The only routine maintenance
required is the monthly greasing and occasional head space adjustment; see Section 6-2 for
more information.
The pump is capable of running in either direction. Thus, the pump reverse feature can be used
to draw fluids back from the process. It is not necessary to install a service air line to purge the
lines before changing molds. Since the pump is capable of achieving extremely high pressures,
it is necessary to regulate the pressure through use of a regulating by-pass line (Fulflo valve).
Because the pump is a positive displacement pump, it will supply the process with rated flow at
or below the rated pressure.
The flow is constant until the pressure reaches the rated pressure. The pressure however is a
function of frictional losses through the process that it is attached to. Systems with large process
connections, ports, and piping will operate at low pressures, while systems with small process
connections, ports, and piping will operate at higher pressures. Once the pressure requirements
exceed the rated pressure, the Fulflo valve will open and bypass the necessary fluid to prevent
high pressures.
Fulflo Valve
A regulating by-pass line featuring a Ful-Flo valve is standard in all units. This is a safety
device to prevent excessive pressure in the event that the delivery line is obstructed. Each Ful-
flo valve is factory preset to limit system pressure as specified by the customer. It must not be
tampered with in any way.
In the event of an obstruction in the line, the Fulflo valve will open and divert fluid from the
delivery TO PROCESS line to the return From Process line. A constant flow of fluid is
maintained through the heater tank to prevent damage to the heating elements and fluid.
Cooling (Optional)

The specially-made shell and tube heat exchanger is provided as optional equipment in this unit.
The design features U- tube construction and copper-nickel tubes for durability and optimal heat
transfer.
The modular construction allows the tube bundle to be easily removed for periodic cleaning.
Additionally, check valves are installed on the water supply and drain lines to prevent water
from back flowing into the heat exchanger from a closed drain or into the water supply piping.
The controller automatically regulates cooling by opening and closing the cooling solenoid.
This allows the proper amount of cooling water to pass through the tubes of the heat exchanger
and out the drain. A water supply of 75 psi (517.1 kPa/5.2 bars) maximum is required for
connection to the heat exchanger.
Connection Lines
Connections for TO PROCESS and FROM PROCESS lines are 1" NPT (25.4 mm). Water
connections for COOLING WATER SUPPLY and COOLING WATER DRAIN are 0.75” NPT
(19.1 mm). (see Section 3.) The customer is responsible for conversions to metric standards.
We stock many lengths of flexible metal hose; the part number is 572-16969. State the length of
hose you want when ordering.
Component failure may result in high-temperature oil spray, causing serious injury or death.
Make sure hoses, valves, and other components installed in your process can withstand
maximum temperature and pressure of the M unit; check unit nameplate for specific
capacities. All components must be carefully inspected for condition before installing. Make
sure you have factory components if you have any doubt.
Electrical System Controls
simplicity of operation. The switches are clearly labeled as to their function. Your M unit has a
system status board so you can evaluate the status and performance of the unit at a glance. Pilot
lights are provided to indicate key unit functions.
An audible alarm is standard with your unit. The alarm will sound in the event of the following
conditions:
• motor overload
• safety thermostat trip (over temperature)
• low fluid pressure
• low fluid level
• high fluid level (optional)
Push the ALARM SILENCE button to silence the alarm. See Section 5-1 on page 26 for more
information on control functions.
Electrical Panel and System Components
The pump motor and immersion heater operate on three-phase, 50/60 cycle nominal voltage
with the control circuit at 115 V single phase. The control circuit voltage is provided by a single
phase machine tool transformer with primary fuse protection and a grounded secondary. A main
power disconnect is included as for ease of service. The electrical panel is UL listed and
complies with N.F.P.A. 79 provisions.
All components are IEC rated for long life and reduced maintenance. The heater elements are
branch fused, and protected from contactor welding by a separate primary voltage contactor.
The pump motor is controlled by a full voltage magnetic reversing starter, with fused branch

circuit overcurrent and thermal overload protection. Many additional features are available as
options.
A NEMA 12 enclosure is standard, with NEMA 4 available as an option.
Air Purge
Upon initial start-up and mold/process change-out, you’ll need to purge all air and water from
the system. The M unit has appropriate valving to ensure complete purging.
Failure to purge the system of air before heating may result in serious injury or critical
system and equipment damage.
Make sure you properly purge the system of air before starting the heater cycle
Pressure Switch
A pressure switch is built into each unit to guard against heater damage. This feature prevents
the heater elements from being energized unless the pump is running and fluid is in the system.
After a preset time, the pump shuts down if the fluid pressure is not re-established. The pressure
switch is preset at the factory; do not tamper with it.
Safety Thermostat
The safety thermostat is a J-Thermocouple sensing, adjustable, fail-safe device located in the
heater tank. This is to guard against the unlikely event of “runaway” heating. If overheating
does occur, the safety thermostat shuts down the heater outputs and sounds an audible alarm. A
red pilot light on the status board also illuminates.
The unit continues to pump fluid through the system to prevent heater damage. Auxiliary
factory installed alarms such as beacons and klaxons are available as options.
All controller functions are locked out until the main supply power is disconnected. Resetting
the alarm condition is initiated by depressing the red pump stop button. The reset button is
located inside the electrical enclosure, mounted on the left wall of the enclosure. It is imperative
that a qualified maintenance technician determine and correct the cause of the fault before
resuming operation.
Reservoir Tank
A reservoir tank with sight gauge is standard; usable capacity is seven (7) gallons (26.5 liters).
The tank permits thermal expansion of the heat transfer fluid, and provides make-up fluid.
The reservoir tank may cause serious injury if it ruptures from not being properly vented.
Make sure that the reservoir tank is always properly vented to prevent tank rupture.
The reservoir tank drain is extended beyond the base of the unit for ease of draining. Optional
ball valves are available to further simplify draining.

Midsize Hot Oil Portable Temperature Control Unit
3-2 Safety Features
This section includes information on safety devices and procedures that are inherent to the
portable hot oil tcu. This manual is not intended to supersede or alter safety standards
established by the user of this equipment. Instead, the material contained in this section is
recommended to supplement these procedures in order to provide a safer working environment.

At the completion of this section, the operator and maintenance personnel will be able to do the
following:
•Identify and locate specific safety devices.
•Understand the proper use of the safety devices provided.
•Describe the function of the safety device.
Safety Circuit Standards
Safety circuits used in industrial systems protect the operator and maintenance personnel from
dangerous energy. They also provide a means of locking out or isolating the energy for
servicing equipment.
Various agencies have contributed to the establishment of safety standards that apply to the
design and manufacture of automated equipment. The Occupational Safety and Health
Administration (OSHA) and Joint Industrial council (JIC) are just a few of the organizations
that have joined with the plastics industry to develop safety standards.
Every effort has been made to incorporate these standards into the design of the portable hot oil
tcu; however, it is the responsibility of the personnel operating and maintaining the equipment
to familiarize themselves with the safety procedures and the proper use of any safety devices.
Fail Safe Operation
If a safety device or circuit should fail, the design must be such that the failure causes a “Safe”
condition. As an example, a safety switch must be a normally open switch. The switch must be
held closed with the device it is to protect. If the switch fails, it will go to the open condition,
tripping out the safety circuit.
At no time should the safety device fail and allow the operation to continue. For example, if a
safety switch is guarding a motor, and the safety switch fails, the motor should not be able to
run.
Safety Device Lock-Outs

Some safety devices disconnect electrical energy from a circuit. The safety devices that are
used on these temperature control units are primarily concerned with electrical power
disconnection and disabling of moving parts that may need to be accessed during the normal
operation of the machine.
Some of the safety devices utilize a manual activator. This is the method of initiating the safety
lock out. This may be in the form of a plug, lever, or a handle. Within this lockable handle,
there may be location for a padlock. Personnel servicing the equipment should place a padlock
in the lockout handle.
In addition to the safety devices listed above, these temperature control units are equipped with
a line cord plug. This allows the operator or maintenance personnel to unplug the tcu from its
power source and tag it out. The plug can then be tagged with any number of approved
electrical lockout tags available at most electrical supply stores.
Always disconnect and lockout all electrical power and pneumatic (i.e. compressed air)
sources prior to servicing or cleaning the temperature control unit. Failure to do so may
result in serious injury. No one but the person who installed the lockout may remove it.

Chapter 3: Installation
3-1 Work Rules
The installation, operation, and maintenance of this equipment must be conducted in accordance
with all applicable work and safety codes for the installation location. This may include, but is
not limited to OSHA, NEC, CSA, and any other local, national, and international regulations.
• Read and follow these instructions when installing, operating, and maintaining
this equipment. If the instructions become damaged or unreadable, obtain
additional copies from ACS Group.
• Only qualified personnel familiar with this equipment should work on or with
this hot oil temperature control unit.
• Work with approved tools and devices.
• Disconnect the electricity before maintenance or service.
If the unit is installed with a power cord that can be un- plugged, unplug it. If the unit is
permanently wired to a power main, make sure that a fused power disconnect is installed to
allow the disconnect to be locked in the OFF position. Open and lock out the disconnect
installed in the control enclosure.
3-2 Installation Requirements
Make sure that you meet the following requirements when installing and operating your M hot
oil temperature control unit.
Installation Location Considerations
Locate the M unit as close as possible to the process for proper circulation and temperature
control. Take care when selecting a location. The area surrounding the unit must be free of
obstructions to ensure proper ventilation of internal components. Allow a minimum clearance
of at least 30 inches (76 cm).
Make sure that the unit location is not in a confined space to ensure proper air circulation.
Special air circulation/ventilation is required for units operating at temperatures exceeding
500ºF (260ºC). Vapors can escape from areas such as the reservoir tank during high temperature
operation.
Harmful vapors may be generated from thermal fluid during high temperature operation.
Prolonged or repeated exposure of these hot-generated vapors may result in eye and
respiratory tract irritation. Avoid contact or inhaling harmful amounts of material. Consult
the Material Safety Data Sheet (MSDS) for precautions and instructions for the thermal
fluid you are using.
Before storing your M temperature control unit, make sure you remove
all residual water with compressed air to avoid a potential freezing
hazard. See Section 6-3 for more information.
Note the following table of ambient temperature ranges permitted for storage
and operation:

You should preheat the process heat transfer fluid first if you want to start the
unit below an ambient temperature of 30ºF (-1ºC).
3-3 Connecting Piping
Make sure that all external piping is properly sized to reduce external pressure drop as much as
possible. Do not install process or water supply/drain piping smaller than the fittings on the unit.
If the water supply piping is larger than unit fittings, reduce the pipe size at the unit.
The following table lists M/TCU pipe sizes.

Always use a backup wrench to support M unit piping when making
connections. Make sure all external piping is supported independently
of the M unit.
It is recommended that you have strainers installed on the cooling water inlets and customer-
supplied shut-off valves on all piping connections. Use common black welded pipe for
permanent installations.
The M is designed to operate with an open, unrestricted drain line. Steam rapidly expands
within the heat exchanger, so any overpressure condition from backpressure or standing
columns of water against the drain must be avoided.
If you must use a pipe joint compound, use a compound that can withstand the high
temperatures and pressures of your M unit. Always insulate all piping to prevent burn hazards
and to retain heat. Make sure insulation is properly rated for maximum operating temperatures
of your M unit.
Piping Considerations for Mobile Installations
Because your M unit is fitted with casters, its portability is well suited for multiple applications.
You can purchase high-quality flexible metal hose to enhance the mobility of your M unit; state
the length you want when ordering.
Although they cause a drop in pressure, you can also install quick disconnects to your M unit.
However, do not install check valves with quick disconnects unless absolutely necessary!
