Air Curtains
Introduction
Basic features
Doormaster air curtains form an unobtrusive aerodynamic
barrier in order to suppress the free flow of air between an
inside and outside environment, at the entrance to a building
for example. A second integral function of the curtain is the
mixing of the air that remains after entering with the air that
has been heated in the room where the curtain is installed,
which reduces the negative feeling evoked by the flow of
cool air. When the curtain has been properly designed, it
increases the comfort inside and, at the same time, reduces
the operating costs for the building. Doormaster Air Curtains
are intended for installation inside in a dry environment
and for mounting in a horizontal position above the intake
opening. The curtain operates in air void of coarse dust
particles, greases, chemical vapors and other contaminants.
The curtain is intended for an environment with a normal
influence classification (in accordance with the Czech norm
ČSN 33 2000-1 ed.2). Its use is prohibited in an aggressive
environment, outdoors, in a moist environment with the
danger of condensation or in an environment with a dangerous explosion! The version with electric heating and the
version without heating can be operated even at temperatures as low as -5°C (under the condition that there is no
condensation in the environment). The version with a water
exchanger (W) is not safeguarded by anti-freeze protection
and must be installed in a non-freezing environment (+5°C
to +40°C). Otherwise it is necessary to ensure a sufficient
supply of heated water so that the medium in the water
exchanger does not freeze.

Air Curtains C1
Basic information
Usage
DoorMaster curtains of the C1 series are intended for inside installation above an entrance door. The maximum
installation height recommended is 2.5 m. Due to their
construction, they are designed for smaller areas where
there is frequent movement of people. Their modern
design enables them to be used in architecturally demanding structures. Typical places for their installation
are administration buildings, stores, hotels, restaurants,
banks, hospitals, post offices, gasoline stations etc.

Description of construction
The covering panels are made of lacquered sheet metal
and fastened to a frameless construction. The sidewalls are
laminated. The basic version comes in the color shade of RAL
9002. The internal components are from leading European
manufacturers. Special tangential fans ensure quiet running
and low-energy operation. Over-all protection for the covered curtain is IP 20. The fans are furnished with motors that
have a temperature insulation for windings of the F class.
Manner of hanging
C1 curtains are hung on M8 hanging rods behind a hanging
profile. For hanging the curtain on a wall, you can order
wall-mounting consoles as an accessory (see Accessories).
The hanging profile is a component of the curtain's standard
delivery.
Lateral version of the curtains
The lateral version of the curtains is determined according
to the view towards the intake panel. The C1 curtain with
water heating is manufactured as right-hand, i.e. the connection of the water heaters is on the right side. The electrical
connection of the C1 curtains is also on the right side.

For more see the chapter "Chaining of Curtains", page 16.
Heating of air
The heating of the air is the second important function of
the curtain. The heating provides the mixing of the cool air
entering into the room with the heated air flowing from the
curtain. The curtains are delivered with water or electric
heating. The use of curtains without heating is suitable
only in exceptional cases where the heating of the air is
not wanted (in cooled areas for example).
Electric heating
The heating of the air (versions E1 and E2) is accomplished
by means of an electric heating register that is formed from
stainless, low-temperature heating rods with a large heatexchanging surface. You can select the electric heating output from two variations - the output variation is determined
by the letters E1 and E2 in the curtain designation: E1 is
a variation with a lower heating output; the variation E2
has a higher electric heating output. On curtains in the E1
version, only the whole output can be switched; on curtains
in the E2 version, the whole or one-half electric heating
output can be switched.
The protections against the over-heating of the electric
heater or of the curtains are listed in the chapter "Control"
on page 12.

Heating, heating outputs
Water heating
The water heating (version W) is provided by a two-row
water heater with vanes. The curtains of the C1 version are
equipped with one body of a water exchanger in all lengths.
Thus the connection of the water heating is only on one
spot. The curtains with a water exchanger are designed for
a heating medium with a maximum temperature of 90 °C
and for a maximum operating pressure of 1.6 MPa.
When high-temperature heating is employed (max. 130 °C), it
is necessary to equip the feed-in of the heating medium with
a valve controlled by a thermostat (TVW-P, see page 16) and
limit the output of the exchanger to the max. temperature
of an outlet air of 50 °C (setting of the thermo-valve head)
or to use a control by means of a mixing set.

When operating a curtain at a lower speed step, the temperature of the return water can rise to the value given by the temperature drop (max. 5°C). In case there are problems with such an increase, we
recommend using the thermostat valve (TVW-P, mounted on the intake branch) and setting the controller (head) at the value of the temperature of the outlet air listed in the column delta t (°C) in the
I. output step (for example, the C1-W-100 curtain, warm-water circulation 60/40: set the controller at a value of max. 33°C). The thermostat valve reduces the flow of water, thus ensuring its greater
cooling. By doing so, the maintaining of the temperature drop is guaranteed. For warm-water circulations above 90/70, it is necessary to use a thermostat valve, and by setting it at max. 50°C, there is
ensured, among other things, that the temperature of the return water does not exceed the specified value given by the temperature drop.

In the case of electric heating, the outlet temperature of the air is dependent on the output step selected for the fans and
the heating step selected.
The heating yield [°C] can be determined roughly according to the general formula:
∆T=Q[W]*0,95*3600/(V[m3/h]* ρ[kg/m3]*c[J/kgK]), where ρ is the density of the air at the presupposed temperature of
(+20°C: 1.188 kg/m3) and c the specific heating capacity of the air at the presupposed temperature of (+20°C: 1010 Jkg-1K-1).

for inside installation above an entrance door. The
maximum installation height recommended is 3 m.
Their modern design enables them to be used in architecturally demanding structures. Typical places for
their installation are administration centers, hypermarkets, restaurants, post offices, garages, warehouses etc.
Manner of hanging
D2 curtains are hung on M8 hanging rods behind a hanging
profile. The hanging profile is a component of the curtain's
delivery.
Illustration 7 - hanging profile
Description of construction
The D2 curtains are formed by an internal chassis and covering panels of lacquered sheet metal in the color shade of
RAL 9002. The exhaust chamber is furnished with anti-noise
insulation. The removable intake panel with an integrated
filter insert and a bottom service panel ensure easy access
to the internal elements.
Components from leading European companies are used in
the curtains. The radial fans that suck on both sides have
three-step speed control. The motor and impellers are on
a common shaft. Over-all protection of the covered curtain
is IP 20. The fans are equipped with motors having a temperature insulation of the windings of class F. The motors
are furnished with a lead-out thermo-contact (to the cable),
which ensures that the power supply to the motor or to the
electric heating is disconnected when there is an overload.
Short-circuit protection of the motors and control circuits
is provided with the help of front-end fuses.

Lateral version of the curtains
The lateral version of the curtains is determined according
to the view towards the intake panel. The D2 curtain with
water heating is manufactured as left-hand, i.e. the connection of the water heaters is on the left side. The electrical
connection of the D2 curtains is on the right side.

Heating of the air
The heating of the air is the second important function of
the curtain. The curtains are delivered with water or electric
heating. The use of the low-temperature curtains (without
heating) is suitable in reasonable cases when the heating
of the air is undesirable.
Electric heating
The heating of the air (versions E1 and E2) is accomplished
by means of an electric heating register that is formed
from stainless, low-temperature heating rods with a large
heat-exchanging surface. You can select the electric heating
output from two variations (see the Table 4). The output variation is determined by the letters E1 and E2 in the curtain
designation. E1 is the variation with a lower heating output
(2 steps of output); the E2 variation has a higher electric
heating output (3 steps of output).

Illustration 12 - curtain with water heating
Water heating
The water heating (W version) is provided by a three-row
water heater with vanes that is formed by one exchanger
body for lengths of 1 m, 1.5 m and 2 m and by two exchanger
bodies (double connection) at a curtain length of 2.5 m. The
curtains with a water exchanger are designed for a heating
medium of up to a maximum temperature of 90 °C and for
a maximum operating pressure of 1.6 MPa. If the heating
media inlet temperature used to heat the heat exchanger
is greater than 70 °C, it is necessary to fit a thermostatically
D2-W-250 curtain has two separate connection circuits
(2 connections); D2-W-100 + D2-W-150.

When operating a curtain at a lower speed step, the temperature of the return water can rise to the value given by the temperature drop (max. 5°C). In case there are problems with such an increase,
we recommend using the thermostat valve (TVW-P or TVW-R, mounted on the intake branch) and setting the controller (head) at the value of the temperature of the outlet air listed in the column delta
t (°C) in the I. output step (for example, the D2-W-100 curtain, warm-water circulation 60/40: set the controller at a value of max. 34°C). The thermostat valve reduces the flow of water, thus ensuring
its greater cooling. By doing so, the maintaining of the temperature drop is guaranteed. For warm-water circulations above 70/50 °C, it is necessary to use a thermostat valve, and by setting it at max.
40 °C, there is ensured, among other things, that the temperature of the return water does not exceed the specified value given by the temperature drop.

Air Curtains
Control, protection, blocking
Connection and protection
„„ As standard equipment, the curtains are furnished with terminals for connecting an external device
(switches / change-over switches) – the curtain does
not carry any control elements.
„„ Preliminary protection against a short-circuit must be provided by a trip release apart from the curtain.
„„ To safely disconnect the device from the electricity
network, there must be a front-end, main service,
locking shut-off switch.
„„ The lead-in and control cables are led into the curtain
from above; the curtains are furnished with sealing
bushings on the upper side.
„„ The motors of the fans on all curtains are furnished with protective thermo-contacts.
„„ The curtains have all the necessary protection
elements for ensuring the safety of their operation.
Control of fan speed
A reduction in speed limits the curtain's efficiency; nevertheless in some applications, it is expedient to use such a
measure (particularly for the function of additional heating;
when the door is shut, for reducing operating noise).
In the basic version, D2 curtains are equipped with motors
whose output can be controlled in 3 steps by adding a suitable front-end controller.
In the basic version, C1 curtains are delivered without a
control of fan speed - upon request, a 3-step speed controller
can be integrated into the curtain. The controller weighs
approximately 1.5 kg.
Any suitably dimensioned, single-pole switch can be used
for switching one-speed curtains. The manufacturer of
the curtain does not deliver such switches. Controllers for
curtains with a control of fan output can be ordered as a
separate accessory together with the curtain, see page 14.
Note: Wiring diagrams for the curtains and a description
of the connecting terminals are contained in the installation instructions, which are enclosed in every curtain.
Note: The controlling (room) thermostat must be located
in an area that is influenced by the curtain's heating (close
to a door, on the wall "under the curtain"). For a table summarizing the output classification of the curtains with electric
heating and for the possible use of controllers, see page
15, table No. 5. Wiring diagrams for the curtains and a description of the connecting terminals are contained in the
installation instructions, which are enclosed in every curtain.
Protection of the electric heater
The basic internal (operating) control of the outlet air
temperature is provided by means of a built-in (control)
thermostat.
The maximum permissible temperature setting is 45 °C,
which is also the one set by the manufacturer. Should it
be necessary, a correction of the setting downward can be
made. Should the temperature that has been set be exceeded
during the operation of the curtain, the thermostat disconnects the heating register, and the fans continue to run at
the speed set by the controller; the register begins to heat
again after things have cooled down.
Note: In some cases - according to the step set for fan speed
(full or medium speed), or to the heating step set, and according to the surrounding conditions (quite cool) - the
temperature set does not have to be reached at all, and the
register can operate without interruption.
With regard to the thermal inertia of the heating register,
the switching of the curtain's running by a door contact is
unsuitable for curtains with electric heating - the warming
up of the heating register usually takes longer than the
opening and closing of the door.
Blocking of the electric heater's running
The electric heater of a door curtain operates only when the
fans are running (switching of the fan's contactor), and that
at any speed step. Should there be no switching of the fans'
running, there is no switching of the electric heater either.
Control of C1 and D2 electric heating
C1-E1 curtains are equipped with an electric heater with
one section, which makes only one-step operation possible,
i.e. during heating control, full heater output is switched.
The other curtains with electric heating, i.e. C1-E2 and all
D2 (E1 and E2) curtains, are equipped with an electric heater
that is divided into two separate sections, which make multistep operation possible, see table 5 on page 11.
The two-section heating register can be controlled by a
double switch (I-II), or it can use the RAB 90E three-step
controller (see the chapter "Accessories").
According to the temperature of the air with the help of a
room thermostat, an automatic control can be substituted
for the manual control of heating output, see the chapter
"Accessories".
The switching of the heating register occurs instantly, which
also holds true for multi-step switching, (always full output).
In specific cases, it is possible to use a thermostat combined
with an integrated three-step control of fan speed.

Cooling down of the electric heater
When the curtain is switched off (switching off on the
controller) at the moment the temperature is higher than
that set on the thermostat, there is a switching to the
highest output step in order to immediately cool the device down. The motors will be stopped automatically as
the temperature drops.
Protection against overheating (operating and
control thermostat)
Curtains with electric heating have two protective loops
with thermostats that cannot be set:
„„ The SM2060 / 60° C protective operating thermostat.
„„ The same system as the operating control, the
protective operating thermostats (60 °C) are located
on the casing of the electric heater and on the spot of
the fan (SM2060). They are connected in series with
the windings of the electric register's contactors.
„„ The SM2080 / 80 °C protective emergency thermostat:
„„ The emergency thermostat (SM2080) ensures the
signal for the safety disconnection of the whole
curtain (i.e. the switching off of the main fuse for
the inlet) in the event that the temperature exceeds
the maximum tolerable limit on the body of the
motor or on the heater's casing. The curtain must
have a preliminary protection at the inlet that has an
under-voltage ejector coil, which must be connected
to the terminals of the emergency thermostat's (TK-TK)
circuit - according to the enclosed connection diagram.
Important:
The curtain must have a preliminary protection at the inlet
that has an under-voltage ejector coil, which must be connected to the terminals of the emergency thermostat's (TKTK) circuit - according to the enclosed connection diagram.

Control of the water heating
As standard equipment, the curtain with water heating does
not have any means for controlling the temperature of the
outlet air or for heating it.
To avoid overheating of the motors and wiring, it is advisable
to connect the exchanger to a hot-water circuit with a max.
temperature of 90 °C. If high-temperature heating (max.
130 °C) is used, the inlet of the heating medium must be
throttled using a thermostatically-controlled valve (for the
description, refer to the chapter Accessories). Otherwise (if
the temperature is exceeded) the air curtain can be switched
off by the motor protection thermostats.
The outlet air temperature of water heaters can be controlled using a capillary thermostatic valve TVW-P (direct).
The valve is installed in the inlet heating water branch in
front of the heat exchanger and outside the air-curtain
(only the capillary probe is inserted into the air-curtain).
D2-type air-curtains enable the valve to be completely
installed into the device TVW-R (corner).
An electric thermostatic valve TVW-E (control ON-OFF,
transposition time 3 minutes) can be used to enable the
heating water inlet to the heat exchanger to be opened/
closed depending on the room temperature. The valve can
be installed only outside the air-curtain on the inlet branch
- the valve's actuator must not be situated downwards.
Due to the valve's longer response time, this combination
is not recommended if the air-curtain operation is switched
by a door contact. Max. temperature of the inlet water is
up to 90 °C.
Protection of the water heater
With regard to the usage application of the curtains (installation in normal areas), the matter of a specific anti-freezing
protection for the water heater has not found a standard solution; the inside temperature should not drop below +5 °C.
To ensure greater safety for the exchanger in winter conditions, it is necessary to safeguard the heating water (or nonfreezing liquid) and the running of the pump. When these
conditions cannot be met, we recommend dismantling the
curtain and moving it to heated areas.
The version with an emptying valve is at your disposition
upon request.
Enclosed in every air curtain are:
D2 series air curtains offer the option to situate the thermostatic valve inside the device.

Controllers
The means and possibilities for controlling the curtains are
defined in the chapter "Control" on page 12.
The basic control of the curtain's operation without control
of fan output and heating can be accomplished by using
customary wall shut-off switches (ON / OFF). The shut-off
switch is not a delivery component.
For controlling the curtain's operation with control of fan
output or with exterior control for heating, the widespread
Siemens controllers listed below can be used.
The selection of a controller depends on the type of curtain
and on the requirement for control. Table No. 5 illustrates
the functions and usage possibilities of the individual
controllers.
Room thermostats can also be used for C1-W or D2-W
curtains, but only in combination with the TWV-E thermoelectric closing valve (separate accessory).
Note: Control by means of the TVW-P thermostat valve is not
possible. It is also not possible to combine the TVW-R with the
control of heating using a room thermostat.
The recommended types of conductors for connecting the
controllers are listed in table No. 6. Shielding is not necessary.

For door openings that are wider than can be covered by
one curtain, it is necessary to use several curtains (of the
same series type) installed next to each other so that the
total length corresponds to the width of the opening. For
a door that is 2.5 m wide, for example, it is necessary to use
one curtain of 1.5 m length and one curtain with a length
of at least 1.0 m.
In order for the installation of the curtains to be carried out
mechanically and optically in the best possible way, connecting sets must be used (DM SS – accessory).
After the electrical connections have been completed, the
whole group of chained curtains is controlled according
to the instructions listed below by means of a common
control element (controller, thermostat) that is connected
to the first curtain in the group of chained curtains; on C1
curtains, to the additional external switching block for the
running of the fans. The control operates, however, on the
same principles as if there was only one curtain.

Mechanical connection of C1 curtains
The mechanical connection of C1 curtains is possible only
with the help of a connecting set. The connection is possible only from above and ensures a fixed distance between
the curtains. For every connection of two curtains, one
connecting set is necessary (separate accessory DM SS C1).
The curtains are chained with the sidewalls.
Electrical connection
a) Fan control
For fans without speed control, the maximum number of
curtains is given by the dimensioning of the switch used
for the running of the curtains; the curtains are connected
parallel (for the ABB TANGO No. 1 switch, for example, a
maximum of 2 curtains simultaneously), or it is necessary
to use a connection across an external contactor.
Chained curtains with a built-in, three-step control (C1/
TR) can be controlled only across an additional, external,
switching and separating element - relay, contactor - for
each output step, one pole for each curtain (the same output
steps of all curtains are lined up parallel). The individual
relays or contactors (or groups) can then be switched by a
common three-step controller.
Air Curtains
Functions and combinations
b) Control of electric heating
To provide joint control (switching) of the electric heating
of several curtains with electric heating, a type variation of
the curtains is delivered which makes a simple joint control
of heating possible. Thus the two curtain variations are differentiated by version, designation and code:
„„ The basic curtain (standard version for a separate
installation) is used only as the last one for an
installation in the context of a chained group.
„„ The curtain with the possibility of connecting the
control of the following curtain in a chain (the first to
penultimate one in a group of chained curtains) – it
has the letter "M" (from the word "Master") on the end
of the type designation. This version makes it possible
to directly connect the control of the electric heating
of the following curtain to the prepared terminals
(XS) and thus to realize the chaining of the switching
for the electric heating. This does not influence the
fan common switching, and it must be ensured by an
external controller, see above.
Note: The extended version M does not solve the switching
of the fans, and it is necessary to provide for it externally according to the previous text.
c) Curtains with water heating and thermo-electric control
with a room thermostat
The standard curtain version and control accessories are
used for the chained control of water heating.
The thermostat can control as many valve actuators as its
electric-output dimensioning allows, or it is necessary to
use an output switching element (relay). The actuators are
switched parallel. Apart from a separate installation to each
exchanger (curtain), it is possible to design a valve and an
actuator for the common feed-in of water to several curtains
(the valve must have the appropriate dimensioning for flow,
and an actuator corresponding to the valve must be used).
Mechanical connection of D2 curtains
The curtains can be connected to each other in such a way
that they form an optically unobtrusive whole. The connection is done with the help of a connecting set (separate
accessory DM SSD2).
Illustration 24 - joining of connection of D2 curtains
terminals (XS) and thus to realize the chaining of the
switching for the electric heating and for fan speed.
„„ The construction of the curtains makes a direct
internal electrical connection possible by means of
the prepared bushings in the supporting aluminium
sidewalls.
b) Curtains with water heating and thermo-electric control and with a room thermostat
The standard curtain version and control accessories are
used for the chained control of water heating. The thermostat can control as many valve actuators as its electric
output dimensioning allows, or it is necessary to use an
output switching element (relay). The actuators are switched
parallel. Apart from a separate installation to each exchanger
(curtain), it is possible to design a valve and an actuator for
the common feed-in of water to several curtains (the valve
must have the appropriate dimensioning for flow, and an
actuator corresponding to the valve must be used).
Installation instructions
You will find all the information necessary for the correct
installation, mounting, connection and putting into operation, including safety instructions, and for operation, maintenance and servicing of the equipment in the installation
instructions, which are included in every curtain.
Electrical connection
a) Fans and electric heating
The electric chaining of the curtains is not limited, and no
further specific external accessory is necessary for it.
A suitable combination of the type variations of the curtains provides the possibility of a simple chaining. The two
curtain variations are differentiated by version, designation
and code:
„„ The basic curtain (standard version for a separate
installation) is used only as the last one for an
„„ Installation in the context of a chained group.
„„ The curtain with the possibility of connecting the
control of the following curtain in a chain (the first to
„„ Penultimate one in a group) – it has the letter "M" on
the end of the type designation. This version makes it
possible to directly connect the control of the electric
heating of the following curtain to the prepared
