Double flux heat recovery unit, up to 90% efficiency. The range consists of 2 sizes and covers an air flow range from 400 up to 2300 m³/h. Apart from heat recovery, many other configurations are available in terms of air treatment such as water- or electrical heating or filtration.
The HRB unit is supplied in three basic versions:
- Without air quality sensor
The control system controls the unit is semi-automatic mode. The air flow is constant as set by the user. The time modes of freecooling, recuperator defreezing, etc. operate automatically.
- With CO2 concentration sensor
The air flow is controlled automatically based on the concentration of CO2 in a range from 400 up to 2000 ppm. The time modes of freecooling, recuperator defreezing, etc. operate automatically.
- With relative air humidity sensor
The air flow is controlled automatically based on the in a range from 30 up to 100%. The time modes of freecooling, recuperator defreezing, etc. operate automatically.

HRB, 10, CO2
Explanation
HRB = Type Heat recovery
10 = Nominal air flow 1000m³/h, 20 = Nominal air flow 2000m³/h
CO2 = With CO2-sensor, H2O = With H2O-sensor
