WATER HEAT EXCHANGER High-performance heat exchanger made of copper and aluminium. ADJUSTABLE AIR STREAM Air blades installed in the outlet of heater section direct air into the occupied area. Variable angle of blades ensures adjustment of air barrier to the door opening area. QUIET OPERATION OF FANS Centrifugal fans are placed in a casing made of light, durable and sound-absorbing material. Quiet operation and low power consumption in relation to their performance (efficiency). CONTROL SYSTEM WITH BMS PROTOCOLS Advanced control system makes it possible to connect and control units by BMS...

Air curtain range defines the maximum height of installation. For ELiS DUO it is 2,5 m - at this height the fan heater section has an 8 m range. 1st step 2nd step 3rd step distance from the outlet [m] 1st step 2nd step 3rd step distance from the outlet [m]

RECOMMENDED INSTALLATION DISTANCES Two ways of console installation. ELiS curtains can be installed using pins. CORRECT INSTALLATION The key to the correct operation of the unit is to ensure air barrier on entire door opening space. ELiS DUO can be linked, so covering wider door openings doesn’t make any problem. Incorrect installation may result in heat loss during winter and chill loss in the air-conditioned rooms during summer.

CONTROL SYSTEMS three-way valve with actuator AF system in ELiS DUO unit controls both air streams. If it is needed the two- or three-way valve can be connected to this system. Both curtain and heater sections can be controlled in various configurations: • DUO1 program - is used in the case of curtain’s connection with door switch and TA speed controller or TS speed controller with room thermostat. • DUO2 program - is used in the case of curtain’s connection with door switch and TS speed controller with room thermostat. In this configuration door switch is the overriding controller. In both...

IDLE SPEED When the doors are closed, curtain’s fans are operating with lower speed. This solution eliminates air barrier’s delay, which is caused by the time needed to switch on the fans. A) Doors are closed standby mode. B) Doors are opening rapid start and speed of fans is rising. C) Doors are closing - speed of fans is still higher. D) Doors are closed - back to standby mode. AIR CURTAIN’S SWITCH OFF DELAY TIME It the case when doors in building keep opening and closing constantly, AF system makes possible to set time delay of the switching off the curtain or returning it to the idle...

BMS PROGRAMMING AF system enables to connect the unit to BMS (Building Management System). It is equipped with communication protocol MODBUS in RTU mode. Communication takes place at a speed of 9600 (without parity control, 1 bit of stop, 8 bits of data, RS485). It is possible to set up to 255 addresses. Thanks to BMS you can get the access to control a 3-step fan speed regulation and valve or electric heaters operation. Control of the operation via BMS does not exclude the control by manual controllers. In this case, unit operates according to the last set signal. MODBUS Register Address...

CONNECTION DIAGRAMS AF SYSTEM - UNITS CHAINING It is possible to connect more ELiS DUO units to each other. All of the control system components must to be connected to the first device (MASTER). Control signals are transmitted to the other units (SLAVE) by CW wire (with RJ12 plugs) - it is possible to connect up to 5 units in this way. power supply power supply power supply
