Air curtains

Application, Operating Conditions and Construction

Information from the manufacturer

DoorMaster door curtains are manufactured in compli-

ance with the valid Czech and European technical regu-

lations and technical standards.

Doormaster air curtains form an unobtrusive aerodyna-

mic barrier in order to suppress the free flow of air be-

tween an inside and outside environment, at the entran-

ce to a building for example, and an environment with 

various conditions (different temperatures, dustiness, 

insects etc).  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.  The manufacturer recommends 

the use of a curtain without heating (version N) only in 

particular cases where there is a reason for it (to se-

parate an air-conditioned room for example) when the 

use of built-in heating is unsuitable. The curtains are 

to be installed and used only in compliance with this 

documentation.  Any other usage does not comply with 

their designated purpose.Neither the manufacturer nor 

the supplier can assume responsibility for damages 

that arise from such misusage, and the user carries 

the whole risk. The operating and service personnel 

must have access to the mounting and operating docu-

mentation, and it is expedient to place it in the vicinity 

of the curtain. The valid safety instructions, norms and 

generally recognized technical regulations are to be re-

spected when handling, assembling, connecting to the 

mains, putting into operation, as well as during repair 

and maintenance work on the equipment.  All conne-

ctions of the device must comply with the appropriate 

safety standards. Any changes and modifications of the 

units that might influence safety may not be done wit-

hout the agreement of the manufacturer/supplier.  The 

same applies to the installing and setting of protection  

equipment and valves. Before installing and using, it is 

necessary to familiarize yourself with the following in-

structions and to respect them.

Usage and operating conditions

  DoorMaster air curtains are designed for inside in-

stallation in a dry environment in a horizontal position 

above the door opening.  The curtains are not intended 

for vertical application and cannot be installed next to 

the door opening.  The maximum height recommended 

for the installation is 2.5 m for curtains of the C1 series 

and 3.0 m for those of the D2 series.

  The curtain can operate in air void of coarse dust 

particles, lubricants, chemical vapors and other con-

taminants.  The curtain is intended for an environment 

with a normal influence classification (ČSN 33 2000-1 

ed.2). Its usage is prohibited in an aggressive environ-

ment, outdoors, in a moist environment with dangerous 

condensation or in an environment with a dangerous 

explosion!  The version with electric heating and the 

version without heating can be operated at temperatu-

res as low as -5 °C (provided there is no condensation 

in the environment).  The version with a water exchan-

ger (W) is not safeguarded against freezing and must 

be installed in a non-freezing area, i.e. +5 °C to +40 °C.  

Otherwise, a sufficient supply of heated water must be 

provided so that the medium in the water exchanger 

does not freeze.

  Door curtains are intended for connecting to the po-

wer-supply system N+PE /50Hz or -

N+PE /50 Hz (according to the type or heating of the 

curtain).  The main lead-in must be properly protected 

with the possibility of a safety disconnection in order to 

ensure a non-voltage state.  The fuse of the main lead-

-in must be equipped with a shut-off release, which is 

an indispensable component of the protection system 

for an air curtain against over-heating.  The electrical 

connection must comply with the diagram. A curtain in 

the standard version is prepared for connecting external 

drivers. The external drivers (shut-off switches) must 

be dimensioned at least to the value for inductive load, 

which is listed in the corresponding tables of this docu-

mentation.

  As standard equipment, the door curtains are fur-

nished with fan motors that have thermal contacts led 

out to the cable that ensures disconnection of the power 

supply to the motor or to the electric heating when there 

is an over-load.  Fuses provide for short-circuit protecti-

on of the motor and of the control circuits.  The fans are 

furnished with motors that have thermal insulation for 

the winding of the F class. 

  Curtains with water heat exchanger are intended 

with no limitations for higher medium temperatures (up 

to 70 °C). For even higher flow temperature is it nece-

ssary to fit thermostatically controlled inlet valve TVW 

TVW-P or-R and the valve head has to limit the heat 

transfer rate to a maximum temperature of 40 ° C (tem-

perature of the outlet air from the air curtain).

The maximum permissible operating pressure of the he-

ating water in the exchanger is 1.5 MPa.  When conne-

cting pipes are used to connect the exchangers, their 

maximum permissible operating pressure (1.0 MPa) 

must be respected.

  The level of acoustic output that is emanated with 

the air from the device is listed below in the correspon-

ding tables for the appropriate types.

Construction of the air curtain

C1 curtains

The curtain's construction is frameless with covering 

panels made of varnished sheet metal in the shade 

RAL 9002 and with plastic sidewalls.  The components 

used are from leading European manufacturers: special 

tangential fans from the company Punker and energy-

-saving EBM motors (with an input power of only 130W 

for a length of 1 m), a two-row  CU/Al water exchanger 

(version W) in all lengths with one connection for the 

media, an electric exchanger with stainless coiled hea-

ting rods (two outputs - version E1 and E2). The over-all 

electric protection of the covered curtains is IP 20.

D2 curtains

The internal chassis with covering panels is made of 

varnished sheet metal in the shade RAL 9002.
