ELiS DUO is a curtain-heater unit, which combines two functions. It is a 2-in-1 unit, which provides an air barrier in the door opening while heating the room simultaneously. The main task is to protect the door opening. Additionally, the auxiliary air stream enables heating of the room.
High efficiency of heat exchange is possible due to a large surface of aluminium fins mounted on copper tubes.
Application
Modern design of the unit makes it especially suitable for buildings with high aesthetic values.
Wherever there is a need of heating the room while providing air barrier in the door opening, e.g. small grocery stores, gas stations etc.
Control System
Basic operation of the air curtain is ensured by built-in connection terminal. Advanced external DRV control system enables communication with BMS and selection of operation mode.
Starting of the curtain occurs when the door is opened, just after the transmission of the signal from a door contact (or thermostat) to the control system. Thanks to 3-step fans it is possible to set the efficiency of the unit. Setting a desired speed on a TS fan speed regulator with thermostat it is possible to adjust the air stream to the conditions in the door opening. For curtains with water heat exchanger the control system enables the control of two or three-way valve. Through communication with the BMS it is possible for the unit to cooperate with other systems in the building.
