The HU-EX6/HC-EX6/Combi HC-EX6 counter-flow heat exchangers are specifically developed for heat recovery in balanced ventilation systems. These heat exchangers allow efficient use of extract air energy for heating or cooling, thus optimizing ventilation and providing healthy indoor climate.

Due to the unique heat exchanger design and the shape of the heat exchanging plates the heat exchange surface is maximized and the pressure losses are minimized. This heat exchanger type is compatible nearly with all ventilation systems.

The supply and extract air streams move in opposite directions toward each other. The heat energy is transferred through the thin plates. Heat recovery efficiency exceeds 90 %.

Hp-EX4 plate heat exchangers are highly efficient heat exchangers that allow to save and reuse thermal energy of air flows, which qualitatively increases the efficiency of the system itself. The cross flows of extract and supply air are separated by the walls of the heat exchanger plates, which prevents the transfer of contaminants, dust particles, moisture, etc. from one flow to another.

Heat transfer efficiency is up to 80%. It is achieved due to the unique design and shape of the heat exchanger plates, in the stack of which heat exchange takes place. The use of polystyrene as a plate material allows for maximum heat transfer compared to similar aluminum plates.

The HC-EX4 counter-flow heat exchangers have a very simple design and contain no movable parts.

The heat exchangers of this series are made of polystyrene plates with cellular structure, which are interconnected with a special glue. The plate height is from 3 to 4 mm.

The warm extract and cold intake air streams are separated with the plate walls and do not come in contact with each other. This design solution excludes transfer of humidity, contaminants, smells and microbes from one air stream to another. Heat recovery efficiency reaches 79 %.

The accumulating mass is assembled into a rigid aluzinc casing.
