Operating conditions
Air curtains are designed for indoor installations (environ-
ment: normal, basic) above or next to the door (possibili-
ties of their arrangements are shown in the figure above).
They are suitable for all kinds of buildings where busier
traffic of freight and manipulating means or persons going
in and out of the building can be expected. Typical instal-
lation sites are production and industrial buildings, sto-
res and transport terminals, gates for trucks, car servi-
ces, garages, car washes, fairgrounds, markets, drying
houses, etc. It is advisable to consult the suitability of a
given type of air curtain for a particular environment with
the manufacturer or the air-handling device designer.
Construction Description
Air curtains are produced in four output rating lines, and
the length of the exit slit is designed for the given door.
As standard, the air curtain and its parts are made of
galvanized sheets (Zn 275 g/m2) without colour coating
finish. Optionally, the air curtain can be delivered finished
with RAL 9002 (or other) baked enamel. The exit slit is
fitted with directing fins.
DoorMaster P air curtains are equipped with a duct radial
fan directly driven by the motor, a VMR inlet screen and
an STB exit slit. The assembly of the air curtain can also
be optionally equipped with an EU3 insert filter. The filter
insert can be partially regenerated. Full regeneration of
the filter insert can only be performed by replacing the
filtrating textile. The air can be heated either by the Cu/Al
finned water heater or electric heater.
Energy savings
The high-pressure DoorMaster air curtains of the "P" se-
ries, developed by REMAK, provide more economical ope-
ration at a significantly lower price compared to competiti-
ve low-pressure air curtains. Operating costs, created espe-
cially by the air heating costs, are less than half compared
to so-called "economy" or "energetically active" air curta-
ins. This extraordinary economical operation of DoorMas-
ter air curtains is based on their high-pressure concept.
These air curtains feature a narrow exit slit which, in spite
of having high pressure loss (hundreds of Pa) and which
need the use of relatively high pressure fans due to high air
flow velocity of 10 to 18 m/s, provide long reach of the air
stream while minimizing air flow rates.
Common air curtains must be equipped with a 4 to 5 times
wider exit slit (approx. 1 0 mm) compared to high-pressu-
re air curtains. They work at a slightly lower air velocity but
require 4 times higher air flow rates. The following table
illustrates the above-mentioned relation comparing the he-
ating inputs of common, economy and high-pressure air
curtains per 1 m height of the air curtain stream.
* The so-called economy air curtain is sometimes identified as an
active one. Heating power input is calculated for ∆t = 20°C.

Installation
Before installation, familiarize yourself with the Sa-
fety Rules on page 12.
The air curtain is delivered disassembled. Individual ele-
ments of the air curtain can be connected together by me-
ans of bar flanges while keeping their prescribed order. Self-
adhesive sealing must be applied between the flanges. The
conductive interconnection of all air curtain parts must be
ensured by the fan-shaped washers. The air curtain must
be anchored to the wall or building structure so that its
stability will be ensured. As standard, the air curtain is not
fitted with any fixing elements.

data and request form are on page 15.
Designing omogram Glossary
Type of Air Heating
It is necessary to determine the type of air heating in ac-
cordance with the installation conditions. Water heating
(W) is the most convenient type of heating. If hot water is
not available, then electric heating (E) can be used. If air
heating is undesirable, then air curtains without heating
(N) can be used; however, the efficiency of such air curtain
is limited.
Orientation and Arrangement of the Air Curtain
The air curtain orientation must be selected in accordance
with the door type. The air curtains for a section door are
always installed on the door's sides. The air curtains for a
wing door are always installed above the door. The single-
sided air curtain arrangement will mostly do for door areas
up to 10 m2. The double sided air curtain arrangement should
always be selected for door areas above 12 m2, or if large
objects (truck, palettes of goods, etc.) are required to be
situated within the door area for a longer time. Another re-
ason for using the double sided arrangement can be the
need to divide the larger ground area of the single side air
curtain into two smaller ones.
Air Flow Velocity in the Exit Slit
The air flow velocity in the exit slit depends on the required
reach range of the air curtain and the selected working
conditions. This parameter is only informative for the de-
sign procedure.
Air Flow Rate (Quantity)
First, the "minimum needed" air flow rate (point ) is deter-
mined using the designing nomogram. This air flow rate is
given by the minimum outlet air flow velocity and the exit
slit area. However, the actual air flow rate corresponding to
the air curtain fan (point ) will be significantly higher, and it
will lie on the intersection of the parabola going through
point , and the solid curve enclosing the upper side of the
respective coloured field.
ecessary Heating Output
The necessary heating output is derived from the actual
airflow rate at ∆t = 20°C. The output of electric heaters can
be 22 kW or 30 kW while controlled by the control unit.
The output of the water heater is given by the heating water
quantity (discharge); its discharge must be ensured by the
pump. This parameter is irrelevant for the low temperature
air curtain (without heating).
Water Discharge
The heating water discharge is an important parameter for
the water-heated air curtains; the heating water discharge
is constant during the air curtain operation. In most cases,
there is no need for further control of the heater output than
just switching the pump on and off. The nomogram has
been created for a temperature gradient of 90/70°C. If the
air curtain processes only circulating air and the room tem-
perature does not drop below +5°C, antifreeze protection
will not be necessary.
This parameter is irrelevant for low temperature (N) and
electric (E) air curtains.
Heating Water Pressure Loss
The heating water pressure loss for the respective water
heater and heating water discharge is included in the no-
mogram. The total pump delivery head is calculated by
adding the piping pressure loss to the heater pressure loss.
This parameter is irrelevant for low temperature (N) and
electric (E) air curtains.
ew Air Curtain Planning
Table 2 - orientation and arrangement
Table 3 - Air control
Reach Range and Length of the air curtain
The reach range is the perpendicular distance from the exit
slit where the air flow velocity is still at the minimum limit.
The reach range and the air curtain length depend on its
orientation and arrangement. The nomogram has been de-
veloped for standard working conditions.
Standard Working Conditions
nPremises with one door (separation of two indoor areas)
nConstant-pressure air handling within the premises.
nWithout ram wind
nIntermittent and momentary door opening
nBuilding without "chimney effect"
on-standard Working Conditions
nOver or under pressure within the premises
nSeveral doors (especially if they are situated
on opposite sides)
nFrequently opened door
nDoor open for longer times
These factors shift the nomogram selection curve to the
right (point).
Air Curtain Control and Regulation
VPC control units (resp. STD relays) can be used to con-
trol, regulate, supply and protect the air curtains. The type
of prescribed controller according to the used heating sys-
tem is included in the following table.
DoorMaster "P" air curtains may only be connected to prescri-
bed controller types. Other ways of protection (control) are not
allowed concerning the warranty conditions. For wiring dia-
grams of the A, B and C controllers, refer to pages 9 to 11. For
a description of controllers, see page 8.

VCP control units
Operating conditions, position and location
VCP-series control units are designed for interior use in
dust-free and dry environments without chemicals. They
are designed according to recommendation of IEC 33
2000-3, enclosure NM, table 32-NM1 for regular effect
classes. At the same time they meet the requirements
of Czech standard ÈSN 33 0300, article 3.1.1 - basic
environment. Protection class of plastic box is IP 54 in
case of closed door and IP 40 in case of opened door.
The control units can be mounted directly on surfaces of
combustible class of A and B according to of Czech stan-
dard ÈSN 73 0823. Permissible ambient temperature
is from +5 to 40°C. The units are fixed in vertical position
either directly on the wall or they are flushmounted 50
mm under the plaster. The cables can be led through
plastic troughs or under the plaster. The unit has to be
positioned taking into consideration easy access of oper-
ators and cable connections.
In case of VCP-E units it is necessary to secure suffici-
ent prote-ction of the lead-in wires so that the residual
over-voltage level would not exceed 1,2 kV.
Construction and materials
All types of VCP control units are built into plastic boxes
with transparent front door behind which the control ele-
ments are located. The outer dimensions of the plastic
box are 275 x 370 x 140 mm. The power section consi-
sts of input terminal board for connection of supply cable,
circuit breakers, contactors and of terminal boards for
connection of the particular elements of the air curtain
unit. Plastics, copper, aluminium and zinc-coated metal
sheets are used in the inner construction. Components
inside the unit are fitted on DIN strips or on printed con-
nection boards.
Control and protection
Fan protection against overheating is secured by fitting
the fan coils with thermocontacts that will disconnect
the protective circuit when the marginal temperature is
exceeded. It will make the control unit disconnect the fan
lead-in wires from power supply. After the coils are coo-
led down and the thermocontacts are switched on, the
air curtain unit fan will not be auto-matically switched on.
The unit can be started by operator after finding out the
cause and repairing the defect. Easy and simple control
is an advantage of VCP control units.
Start and stop
The gate air curtain unit is started and stopped by a
switch on the front panel of control unit marked START
- AUTO. Permanent operation of the unit in manual
mode can be adjusted by switching the switch over
to the START position and the unit operation is indi-
cated by switch control light. Switching the
switch over to AUTO position, the mode of automatic
operation switching by 250V / 0,5 A external poten-
tial-free contact will be set. This contact is to be con-
nected to the control unit terminals. If the contact is
not connected, the unit is switched off in
AUTO position. Electric heated air curtain units have
the safety run-out of the fans secured until the mo-
ment the temperature in electric heater chamber drops.
Definitive air curtain unit stop (for instance seasonal)
is made by switching the main switch off.
By HEATER DISCO ECTI G SWITCH (VCP-E) is it possi-
ble to disconnect manually the electric heater control.
The red control light on this switch indicates switching
the heater on. Temperature of discharge air of the air
curtain unit is set by thermostat upon putting the unit into
operation. By PUMP DISCO ECTI G (VCP-W) we can
disconnect the hot water pump switching, which is other-
wise switched on simultaneously with unit starting. If a
defect occurs on fan or electric heater in operation of the
gate air curtain unit, the control unit will stop unit auto-
matically. After removing the defect, it is necessary to
reactivate the circuit breakers.Then the unit can be re-
started.

Connection of low temperature unit
without heating ( )
Figure 3 shows the connection of the low temperature air
curtain (i.e. without air heating). Protective STD relay ensu-
res the start and stop of the air curtain and overloading pro-
tection of the fan motor. The protective relay will automatically
switch the fan motor off if the maximum permissible motor
winding temperature of 130°C is exceeded. The protective
relay is equipped with a restart button (RESET). The air cur-
tain can be manually controlled by the switch situated on the
STD relay. If switching of the air curtain by an external contact
connected to the door opening mechanism is required, the
contactor must be inserted in front of the protective relay (if
the power supply fails, the fan will be automatically switched
on by the circuit breaker after the power supply is resumed).
The STD relay is designed for indoor and outdoor use in a
chemical-free and non-explosive environment. Degree of
protection is IP54. Maximum permissible ambient tempera-
ture ranges from -25°C to +40°C. The protective relay is enc-
losed in a plastic casing which can be mounted directly on a
wall, or partly embedded into plaster. The protective relay
can also be installed without the plastic casing on the DIN
bar inside the control unit.

Figure 5 shows the connection of the water-heated air
curtain to the VCP-W control unit. The control unit ensu-
res start and stop of the air curtain and overloading
protection of the fan motor. Further, it provides pump
protection. The switching of the pump is related to the
air curtain operation. During the summer season, the
pump can be taken out of operation by switching the
pump trip switch off. The water heating system is not
equipped with antifreeze protection and therefore it may
only be installed in non-freezing areas where the tem-
perature does not fall below +5°C. The air curtain can
be controlled either by the switch situated on the front
panel of the control unit or by an external contact con-
nected to the door opening mechanism; then the air
curtain is automatically started/stopped in relation to
the door opening/closing. For control of simple applica-
tions, an STD relay can be used which simultaneously
ensures overload protection of the fan motor. In such
case, the pump supply and protection must be ensured
separately. The water-heated air curtains have no outlet
air temperature control.

trol to the VCP-E control unit. The control unit ensures
start and stop of the air curtain and overload protection
of the fan motor and protection of the electric heater
against overheating. The electric heater is equipped
with double independent thermal protection which ens-
ures overheating protection in cooperation with the VCP-
E control unit. The air curtain can be controlled either by
the switch situated on the front panel of the control unit
or by an external contact connected to the door opening
mechanism; then the air curtain is automatically star-
ted (stopped) in relation to the door opening (closing) -
however, the heater's temperature rise time must be
taken into account. The control unit ensures safe stop
of the air curtain with an electric heater by the rundown
of the fan until the electric heater chamber is cooled
down. The two-stage control of the outlet air temperatu-
re is carried out in relation to the signal from the control
thermostat (accessory) which is situated in the exit slit
duct behind the fan. The thermostat stem must be pla-
ced in the air stream

Installation, Operation and Service
ons) must be bridged with yellow-green cables or
plated copper cords of min. section 4 mm2, provi-
ded with cable tags and fan-shaped washers.
n The entire air curtain assembly must be intercon-
nected with the VCP control unit by a separate yel-
low-green cable with section area corresponding to
the section area of the main supply conductors,
min. 4 mm2 and larger. This cable is connected to
the PE terminal on the control unit. The additional
interconnection of the air-handling assembly must
be connected to the protective terminal of the con-
trol unit in accordance with ÈS 332000-4-41, table
41 .
n The air curtain must be anchored to the wall or
building structure so that its stability will be ensured.
n When mounting the control unit on a wall, commissio-
ning it or during common operation, make sure you keep
the control unit interior clean. The control unit contains
sensitive electro-mechanical parts and being contamina-
ted with dirt from a construction site (dust, sand, plaster,
etc) it can endanger the safe operation of the entire devi-
ce.
It is essential to pay attention to the connection of
the thermo contacts. The thermo contacts of the fan
must always be connected only to the TK terminals;
otherwise, there are risks of short circuit and ther-
mo contact destruction.
Commissioning
n All the following check and service steps must be per-
formedbefore aircurtain commissioning.
n Beforeputting the device into operationfor the first
time, it is necessary to check the completeness of the
air curtain and the proper fitting of all its parts. In particu-
lar, the completeness, locations and connecting of ther-
malsensors, fan andheater thermo-contacts andprote-
ctive thermostats must be checked.
n The proper installation of fans and heaters must also
bechecked (the arrow indicatesthe air flow direction).
n Special attention must be paid to conductive in-
terconnection of all parts of the air-handling duct
and other related devices.
n The lines connected to the failure inputs must be
checked. The lines must not be short-circuited or broken.
Before starting the air curtain, it is necessary to verify the
aircurtain's responsetoindividual failureinputs.
n Voltages of all three phases must be checked.
n The correct direction of the impeller rotation must be
checkedfollowing the directionofthe arrow onthe fan
cap.To do so, removethe rubber plug fromthe inspecti-
on opening in the fan cup. The direction of the air flow is
notdecisive.
n The rated currents (fromthetype plate) of everycon-
necteddevice must be measuredafter putting the aircur-
taininto operation. These values mustnot exceed the
maximum allowed limits
Wiring and Safety
When handling, installing, wiring, commissioning,
repairing or servicing the air curtains, it is necessa-
ry to observe valid safety rules, standards and gene-
rally recognized technical rules. Every device con-
nection must comply with the respective safety stan-
dards.
n The wiring can only be performed by a worker licen-
sed in accordance with the local legal regulations (ÈÚBP
è. 50/78 Sb., § ). An inspection of the wiring must be
performed before commissioning.
n VCP control units can be connected to the TNS sys-
tem (3x 400V+N+PE). PE and N terminals are indepen-
dently brought out on the control unit inputs. The sizes of
the input trip switches are given by the motor configurati-
on, respectively by the size of the electric heater. Howe-
ver, we recommend verifying the switching capabilities of
protective elements concerning the desired discon-
necting time, overloading of the supply cable, short-cir-
cuit resistance and overloading of the supply cable.
n VCP control units can be connected to the air curtain
via a cable system in accordance with the wiring and
M&C project documentation.
n The air curtain is supplied with power from the
parent distribution board though the circuit breaker.
The size of the circuit breaker is determined by the
designer according to the local conditions and a
connecting device. The air curtain must be provi-
ded with a lockable main switch of red colour on a
yellow base. These elements are not included in
the air curtain delivery. The power supply is con-
nected to the terminals of the terminal box X1.
Other power cables (fan motors, electric heater) are
connected to the terminals of the terminal box X2
situated in the bottom part of the control unit, and
directly to the contactor terminals KM1, KM2 (versi-
on VCP-E). The cables of the 230V AC control circu-
its are connected to terminal box X3.
n It is essential to pay attention to the connection
of the thermo contacts. The thermo contacts of the
fan must always be connected only to the TK termi-
nals; otherwise, there are risks of short circuit and
thermo contact destruction.
n Connecting cables can be led in under plaster or
using cable trays but plastic cable trenches are the best.
To satisfy the EMC needs, it is advisable to lead the sig-
nal cables separately from the power cables, and the
main supply to the control unit must be provided with sui-
table over-voltage protection.
n The protection against dangerous contact of non-
live parts is performed by automatic disconnection
of the power supply combined with additional inter-
connection of non-live parts of the air curtain in ac-
cordance with the ÈS 332000-4-41 standard.
n Self-adhesive sealing must be applied between the
flanges. The conductive interconnection of all air curtain
parts must be ensured by fan-shaped washers.
n All non-conducting parts (e.g. elastic connecti-

Installation, Operation and Service
Operation, Maintenance and Service
The air curtain must be kept in an operable condition.
Guarantee or after-sale service is provided by the manu-
facturer or authorized regional service shops.
Air Curtain Operation Safety Rules
n Proper assembly, installation and commissioning are
conditions for faultless and safe operation of the air cur-
tain, as well as proper attendance by qualified operating
staff.
n The installation and commissioning may be performed
only by qualified personnel or by an authorized service
technician.
n Only personnel who have been provably trained by the
purchaser (manufacturer or authorized service technician)
and warned of possible risks and hazards can operate
the VCP control unit.
n The removal, bypassing or disconnecting of safety
equipment and functions, or protective devices, is forbid-
den.
n Only faultless air-handling components can be used.
Failures which can affect device safety must be removed
immediately.
n All precautions concerning electrical accidents
must be strictly observed. Any actions restricting sa-
fety and/or protective precautions, even temporari-
ly, must be strictly avoided.
n By no means may any guards or other safety
equipment be removed. The device and its compo-
nents may not be operated if safety devices or pre-
cautions are ineffective, or if their functioning is res-
tricted.
n Before opening the door of the switch board, dis-
connect the power supply by means of the main
switch. ever work on an energized device. Use
protective work aids.
n When replacing fuses, the voltage-free state of
the control unit must be ensured and only prescri-
bed fuses and protective elements can be used.
n The harmful effects of electromagnetic emissions
and overvoltage on signal, control, and power
cables, which could cause dangerous unwanted ac-
tions or destroy electronic elements, must be avoi-
ded.
n The sound power level (A) emitted by the device can
reach 72 to 101 dB in relation to the exit slit length and
the system regulation. The complete characteristics of
the fans used, including acoustic data, are available from
the manufacturer.
n Individual components of the air curtain can only be
installed in accordance with the installation instructions.
n After failures like short circuits have been removed,
always check the function of the automatic protective
elements and verify the condition of the grounding inter-
connection.
n Only authorized personnel are allowed to recognize
and remove failures, and put the device into operation.
The same applies to work inside the switchboard (e.g. te-
sting, replacing fuses). The manufacturer is not responsi-
ble for any damage resulting from using procedures other
than those specified in this documentation, and the one
who it bears the risk of such use.
n The thermo contacts can cause a failure by discon-
necting the protective circuits of the fan or electric heater.
If this is the case, the under-voltage triggers of the circuit
breakers are activated, disconnecting the power supply
to these elements of the air curtain.
n Keep the documentation for further use. The installati-
on and operating documentation must be available for the
operating and servicing staff. It is advisable to store this
documentation close to the air curtain.
Operational Inspections
The user must perform regular inspections of the electri-
cal equipment at the prescribed intervals during the who-
le service life of the air curtain in accordance with the re-
spective legal regulations.
Important note: If the heat exchanger is taken out of
operating for the winter season, the water must be fully
drained, e.g. by air blowing, or the heat exchanger sys-
tem must be filled with antifreeze glycol solution. Other-
wise, the water residue could freeze and break the cop-
per pipes. Depending on the operating conditions, we re-
commend checking the filter insert one or twice a year. A
fouled filter must be replaced.
