Heat recovery units RDAF Mini, Midi and Maxi are based on our RDAE unit and develop this further. This series of units is designed to be energy efficient and have low SFPv values. The units have a rotary heat exchanger with stepless speed control, which results in very precise temperature control. 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 RDAF units are equipped with the Fläkt Woods control system Curo®,supplemented by a graphic control panel Curo® Touch or a simpler membrane panel Curo® Basic. The units are primarily intended for detached houses and smaller premises and should be located in cold spaces, for instance in an attic. The connections are placed at the gable ends and the units do not need draining, which is an advantage, especially when replacing an older unit. RDAF is delivered with a 2m connection cable for the control panel.
