SlimAIR Units

Product Code: HRU-SlimAIR

The HRU-SlimAIR HRV is designed for residential buildings. The HRU has a capacity of 250 m3/h @ 100 Pa, generated by energy-efficient EC fans. A plastic (PET) counterflow heat exchanger is responsible for heat recovery. An ERV version with an enthalpy exchanger that recovers moisture is also available.

Built-in electric preheater protects heat exchanger against freezing, wireless radio communication connects controllers and sensors, and all of it is enclosed inside a self-supporting, insulating EPP casing. SlimAIR HRV can be installed in up to 3 positions, thanks to a special condensate drain system.
