PACARE

Air treatment Heat pump 100% fresh air operation

The PACARE is a double flow rooftop heat pump, 100% fresh air operation. The rotary heat exchanger allows energy recovery on exhaust air in both heating and cooling modes. It can maintain the setpoint temperature or be associated to the reversible heat pump cooling cycle if necessary.

Description

The PACARE double flow rooftop heat pump is specially designed for fresh air treatment and preparation in low energy buildings. This autonomous rooftop unit combines an indirect adiabatic cooling system and two counter flow recuperators for maximum energy savings.

 Thanks to its full aluminium structure (frame & casing) that ensures an excellent corrosion protection, this air conditioning and heating system is covered by a 20-year guarantee against corrosion (frame and casing).

This double flow rooftop heat pump is delivered ready to operate and can be installed either on a rooftop or on the ground. The design and selection of components used in our heat pumps ensure significant reliability.

This rooftop comes with a 5-year basic warranty and all ETT services: Commissioning, Audits, Service contracts etc.
