    1. INTRODUCTION This Installation Manual is intended for professionals, qualified to install RHP Pro2 air handling units. Qualified profes- sionals are people with sufficient professional experience and knowledge of ventilation systems and installation thereof, knowledge of electrical safety requirements and having ability to perform works without endangering themselves or others.

  • Page 4: Unit Types And Sizes

    RHP Pro2 – air handling units with a rotary heat exchanger and an integrated heat pump. Rotating wheel (rotor) of a rotary heat exchanger collects heat or cold from the indoor air and transfers it to the fresh supply air. Recovered heat/cold capacity is changed by adjusting the rotor speed.
