Energy recovery roof air ventilator with cross-counterflow heat exchanger

The working principle of a heat recovery ventilation unit is to exchange energy in the air in a two-way exchange system by using heat differences of the inside and outside temperatures. It has several functions; as well as heat recovery it functions as a heat-conductor.
The output of the extractor unit utilises energy from the intake air via an effective heat exchanger
to contribute to reducing the buildings energy requirement. Energy-saving rates of up to 75% can
be achieved with a KRV heat recovery system.

Features:

1>  Different capacity units provide easy and flexible solutions for rooms of all sizes

2>  Consistent performance over long periods of operation

3>  A side air flow design largely increases the life expectancy of the heat exchanger

4>  Easy maintenance - only the filter needs maintenance.

5>  Low noise. Fire foam Fan volute, completely sound-absorbing, less noise, higher heat efficiency.

6>  3 speed air volume control, high, medium, low 3 speed to adjust the air volume.

7>  New high-dormant-pressure with two-way air inlet centrifugal turbine. The units are now equiped with new and improved fan
blades giving the heat recovery unit has a larger deflection diameter. As a result, when air flows, the dormant pressure is increased
and the noise is reduced. High dormant pressure and low noise are reliable and perfect for air conditioning designs.

8>  High quality hydrophilic coating aluminium foil core,with fast thermal conductivity,no secondary pollution and
high heat transfer rate,with higher corrosion resistance.
