DVU-HP Integrated Reversible Heat Pump System The DVU-HP is a complete section with an integrated reversible heat pump for both heating and cooling, and a rotary heat exchanger for effective heat recovery. The section is delivered built into Systemair’s air handling units; Danvent DV and TIME ec, and is pretested from factory ready for operation. The combination of a heat pump and a rotary exchanger ensures a short length and an outstanding operating economy in both heating and cooling situations. The DVU-HP is equipped with two scroll compressors (only one compressor in the two smallest...
