Blue Line KVS

If separate ventilation units are implemented for supply air and exhaust air or if the air lines must be disconnected, the heat recovery can take place via the common circulation system (KVS). Brine serves as the heat carrier, which receives and delivers thermal energy via an air/brine register.

The KVS is inherently robust against any pressure differences between the air lines and provides a perfect separation of exhaust air and incoming air. Thus the use of Blue Line KVS equipment is mandatory for exhaust air of category ETA-4.

With appropriate design, which we guarantee, our Blue Line KVS units meet the ErP Directive according to Regulation (EU) 1253/2014.

The Blue Line KVS units are individually configured and designed according to the air conditioning task to be fulfilled. Due to our modular HKG design, the series of equipment can be individually expanded with the necessary components in each case: integrated mechanical cooling or heat pump (also reversible), cold or hot water register, humidification and dehumidification, etc.
