2.5.1.8. Tender text – Induction unit for displacement ventilation, for vertical parapet mounting, type IG-Q-SB

… units
Induction unit for displacement ventilation – for vertical parapet mounting – for cooling, heating, and fresh air supply along the building facade through window parapets.

Unit to be integrated into the existing parapet cover, with primary air connection and built-in metallic primary air nozzles, consisting of: 

water heat exchanger made from copper piping with aluminium fins and separate circuits for heating and cooling; large fin spacing for easy cleaning as per VDI 6022;

condensate tank inclusive of drain with ½” connector;

primary air box with inspection opening as per VDI 6022;

displacement air outlet for discharging supply air – made up of a blend of primary and secondary air – at low turbulence and low momentum, according to the principle of displacement ventilation.
