The Plate counter-flow heat exchangers 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 %.

Enthalpy heat exchangers are used to transfer both apparent and latent heat energy from one air flow to another.
In the enthalpy heat exchangers of this series an ultrathin polymer membrane is used as a separating
barrier between the flows, which allows through diffusion to transfer not only heat but also moisture.
Due to its atomic structure, the membrane allows only water vapor to penetrate through it, while blocking the transfer of gases, pollution, odors, microorganisms and prevents the spread of viruses.
The enthalpy heat exchangers keep the balanced comfortable indoor humidity in dry winter and hot humid outside conditions.

The EcoFresh Energy, which recovers total energy (sensible and latent), assists in meeting all the requirements of improving Indoor Air Quality (IAQ), humidity control and energy saving.

We offer the Highest Energy recovery rotors & wheels in the world (Aluminium substrate coated with a choice of desiccants). These are incorporated into a Fresh Air Handing Unit or Energy Recovery Ventilator. In some cases, the wheel may be installed standalone with ducts.
