The НС-ЕХ6 / Combi НС-ЕХ6 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 %.
The new generation of the enthalpy counter-flow EC-EX6 heat exchangers offers an alternative to standard heat exchanger models. In case of operation in residential premises with low indoor humidity these heat exchangers keep the comfortable indoor climate due to humidity recovery from the extract air.
This process is possible due to the unique polymer membrane with a microporous structure that enables transition of water vapour molecules, but blocks transition of bacteria, germs, mould, gases and smells. This design enables to keep high hygienic standards also in sanitary areas, kitchen and laboratories and other premises with permanent sources of air pollution. No transition of smells and toxins! Only warmth and water vapours are allowed!
The Hp-EX4 plate heat exchangers are the unique high-efficient heat exchangers designed for efficient energy recovery and re-use. The cross 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.
The heat recovery efficiency is about 90 %! This high heat recovery efficiency is attained due to the unique design, shape and material of the heat exchanging plates. Turbulence in the heat exchanging stack develops even at low speed. The specially designed material of the plates enables to reach higher heat conductivity as compared to standard aluminium plates.
The E-EX4 cross-flow enthalpy heat exchangers are able to recover heat and warmth and to transfer them to the intake air flow.
An ultrathin polymer membrane serves as a partition between the air streams and enables both heat and humidity recovery.
The membrane has a thin polymer barrier film, that allows to water vapour transit through it. At the same time transition of gases, contaminants, smells, microbes and viruses is not possible.
The enthalpy heat exchangers keep the balanced comfortable indoor humidity in dry winter and hot humid outside conditions.
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 plastic 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 applied heat exchanger material enables operation in the temperature conditions from -25 up to +50 °C. The heat exchangers are frost-resistant and keep the high performance after defrosting.
Series R-EX / R-E-EX / R-N-EX / R-K-EX
The rotary heat exchangers have a rotating heat wheel. The accumulating mass rotates permanently between the warm extract and the cold intake air flows. During rotation of the heat exchanger the extract air heat is absorbed with the cold intake flow. Heat recovery efficiency reaches 85 %.
