What is an Enthalpy Heat Exchanger and Why is it Beneficial?

How does an enthalpy heat exchanger work?

An enthalpy heat exchanger is made from a special membrane designed to recover both heat and moisture. Unlike conventional counterflow plate heat exchangers, which only transfer heat, the enthalpy membrane allows part of the moisture from the exhaust air to be transferred to the supply air. At the same time, dirt and bacteria cannot pass through the membrane, making the system hygienic and safe.

Comfort and a healthier indoor climate

With an enthalpy heat exchanger, indoor comfort reaches a higher level. When the room temperature is 20-22 °C, the optimal humidity level is maintained without over-drying the air. In comparison, conventional counterflow plate heat exchangers often remove too much humidity, which then requires additional humidification. With an enthalpy heat exchanger, a healthier and more natural indoor climate is preserved without the need for extra devices.

Summer benefits

An enthalpy heat exchanger is not only effective in winter but also beneficial in summer. It prevents excess humidity from entering the indoor space, helps retain coolness and reduces air-conditioning costs. This makes it an energy-efficient solution for all seasons.

Reliable operation in low temperatures

Another significant advantage is protection against freezing. An enthalpy counterflow plate heat exchanger can operate without freezing at temperatures as low as -15 °C, while standard plate heat exchangers typically begin to ice up once outdoor temperatures drop below -4 °C. This ensures greater reliability and lower operating costs.
