sheet steel housing intake grille with micro-intake grille behind it high-quality powder coated discharge fins each adjustable in 5 stages + Inspection with hidden screws Special design Heating media Dual EC is the energy-saving model for applications in shops and retail. Wherever there is only a limited supply of heating energy available which must be used efficiently, the Dual EC has a special way of fulfilling all the requirements on a modern door air curtain unit. Installation-ready model available in 3 installation variants. Free-hanging, installed flush with the ceiling as a cassette...

+ Made in Germany + ErP 2015 ready / EC fans + Reduced heating costs thanks to dual technology + Certified by TUV-Sud + Robust, self-supporting sheet steel housing + High-quality powder coating + Individual colours available (standard RAL 9016) + 3 installation types + Individual unit lengths up to 2500 mm + Easy-maintenance filter cleaning thanks to micro grille + Aerodynamically optimised double discharge fins + Different heating media possible EC fans The efficiency of the EC fans used by TEKADOOR is > 90% under partial load operation. This is 30-35% higher than for conventional AC fans....

Connection box (LPHW) Simple electrical connection via connection box (voltage supply 230V/50Hz on the top of the unit); connection can optionally also be located at the side.

Data cable connection/interface Simple, standard plug and play connection of the data cable and an optional solenoid valve on the top side of the unit. The connection can be offset on request. Control: Input for the data cable to the control unit. Auxiliary: Output for parallel operation with other units, Double discharge fin The shielding performance of the door air curtain unit is optimised by adjusting the discharge fins. The fins can be adjusted in 5 stages. During the heating period, the discharge fins should be tilted outwards by 10 to 15 degrees to prevent cold air coming in from the...

Only the intake and discharge grilles are visible from below. Ambient air intake is from the underside, on the room side. CAUTION: The inspection panel is on the underside of the unit. Therefore, it is essential that the suspended ceiling...

OPTIONAL ACCESSORIES Thermostatic straightway valve Door contact solenoid switch (Setting range + 25 °C to + 45 °C) limits the discharge temperature (constant supply air temperature limitation). Also available as a 3-way valve. For problem-free, vibration-free ceiling attachment, consisting of M8 threaded rods, up to 1000 mm length, vibration dampers, turn-buckles and counter nuts. In automatic mode switches on the door air curtain in the preselected stages.

Frost protection Solenoid valve thermostat Room thermostat Thermo-electric shut-off valve For monitoring LPHW heat exchangers exposed to the risk of frost. As soon as the temperature falls below +7 °C the fans are switched off and an optional solenoid valve is opened. Opens or closes the heating water circuit in the summer/ winter setting of the control unit, to close the heating water circuit during summer operation or when the air curtain is not working (normally closed). Caution: If solenoid valves or thermo-electric shut-off valves are used, it is expressly recommended to install...
