Home » VHR CF EC

Alaskon Heat Recovery Units (VHR) are designed for saving energy and also improving indoor air quality. VHR units provide convenience and vast application possibilities for ventilation and air-conditioning for residential, commercial and industrial areas by using aluminium plate-type counter flow heat exchangers, recovering heat from air to air. The heat is effectively transferred from warm air to cold air by the heat exchangers with high conductivity, efficiency and performance.
