Heat recovery unit RDAS TECHNICAL DATA Heat recovery unit RDAS 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. RDAF is delievered with 2 m connection cable for control panel. Energy savings RDAS is a heat recovery unit with low energy consumption. To achieve this, highly efficient EC motors are used. Measurements show that the energy consumption of these motors is just 50% - 60% of the corresponding figure for conventional AC motors. RDAS is equipped with a rotary heat exchanger with a temperature efficiency of up to 85% (conditions according to EN 308). Flow diagram Variable speed rotary heat exchanger Highly efficient EC motors Individually adjustable fans Recommended for residential areas of up to 280 m2 (105 l/s) Supply and extract air flow Does not require draining • Easy to install • Easy to service • Automatic limit on moisture recovery (optional) • Graphic control panel Curo® Touch (optional) • Modbus communication Product code example: RDAS-1-1-1-2-0-5-1 Heat recovery unit RDAS with post-heating, moisture control, stan dard filter and Ethernet connection.
