Defro DRX PLUS 400H Recuperator

COMPACT HANGING AHU WITH HEAT RECOVERY

Ceiling recuperator with a thermal wheel, galvanized steel housing and LCD touchscreen

The EVO-T+ compact air handling unit with a CPR counterflow heat exchanger or RR rotary heat exchanger is a compact unit designed for heat recovery ventilation systems in all types of buildings, such as shops, restaurants, laundries, residential buildings, detached houses, etc. The unit can be optionally factory-fitted with an electric reheater or a water heater in the intake section. The unit has a full bypass (100%) of the counterflow heat exchanger. The unit operates on outside air and is powered by electricity.

To maintain the comfort temperature of the supply air at outdoor temperatures below 0°C, an electric preheater is used. A ground heat exchanger (GHEX) can be used to heat the inlet air (fresh outdoor air).

For the inlet and outlet EVO-T+ air handling units, the air flow can be realised in a system of parallel or crossing air flows.
