Air curtains doors are preferablydesignated for use in:

◆ banks and hotels◆ administration buildings◆ light industry◆ trade fair halls, convention or

exhibition centres, and supermarkets.

Model „Li4“Model „Li3“

As a separating medium:

◆ circulation air of room temperature◆ circulation of air heated by electrical

or hot water heater◆ outside air and circulating air heated

by electrical or hot water heater(on demand) can be used.

Air curtains doors type „Li 3, 4“

Assembly: vertical / horizontalTypes: cold air / hot air

(hot water, electrical or steam heated)For door heights of: to 4,2; to 4,8mFor door widths of: 1,5; 2,0; 2,5 mColour: Standard RAL 9010 (white),

optional: all RAL- colours

The air curtains in these types are also suitable for interiorareas, whereby substantial demands in design arefeatured.The air curtains in these types are also furnished asstandard and with EU2-filter, which renders animportant contribution for air purity.

Thermostatic head for2-way or 3-way valveAt customer wish the hot water heat exchanger can be delivered with a built-in 2-way or 3-way thermostatic valve with operating head (range 20-50°C). A part of the operating head is a capillary sensor, which is installed behind the heat exchanger - for exit air and temperature regulation.

3-way valveOn customer wish can be delivered to the heat exchanger an inbuilt 3-way valvewith operating thermosatic head (range 20-50°C) or with an electro-thermic gear.During switching the 3-way valve doesn’toccur any pressure strokes and the valve isrunning also in interpositions. A part of thethermostatic head is a separate capillarysensor, which is placed in the productionbehind the heat exchanger - temperatureregulation of the outlet air.

Electrothermic gear for2-way or 3-way valveAt customer wish the hot water heat exchanger can be delivered with a built-in 2-way or 3-way thermoelectricvalve. It is characterized by silent and trouble-free running. When the thermo gear is under voltage, built-in sensor is warming up, after lapse a time differential, the gear starts to close continuously. At voltage interruption come to a continuous opening of thermo gear. Electro data: 230 V/50Hz-3V, IP 42.

Controller LS-X, LS-XA, Digitron-WAController description: it is designated for operation of cold or warm air curtain doorswith a connection possibility from external operating elements (door contact, room thermostat). Especially it is suitable for aplication with a big frequency of people movingthroug the door. The automatic function is secured by door contact (contact from thedoor automatics in the building), where the air curtain is running on the lowest speedgrade, when the door is closed. When the door opens, it comes to an automatic switchover of fan capacity into a higher speed (2. or 3.speed according to the switch setting); see table of steering.
