Heat recovery unit RDAS is based on our RDAR unit and develops this further. The unit has a rotary heat exchanger with stepless speed control. This allows for very precise temperature control, resulting in higher accuracy of the desired supply air temperature. In addition, a function which automatically limits the rotary heat exchanger’s moisture recovery at high levels of humidity in the indoor air, is available as an optional extra. The RDAS unit is equipped with the Fläkt Woods control system Curo®, supplemented by a graphic control panel Curo®Touch or a simpler membrane panel Curo®Basic. The unit is primarily intended for housing units and smaller commercial premises, and can be located in warm or cold spaces. All connections are at the top and the unit can be wall-mounted or placed standing on the floor or lying on the floor with the door facing up.
