The Energy THE/PS/P series heat recovery units have been designed to provide energy savings in ventilation systems for public and private premises, such as bars, restaurants, offices, shops, etc., by recovering heat from the exhaust air and transferring it to the supply air. Heat exchange between the exhaust air and the supply air takes place through a static counterflow heat exchanger, designed to achieve heat recovery efficiency of up to 94%. The range includes several unit sizes suitable for horizontal installation, covering airflow rates from 300 to 4,000 m³/h. The units are available in both ceiling-mounted and floor-mounted versions. The Energy THE/PS/P units are ErP 2018 compliant, meeting the mandatory requirements of the European Ecodesign Directive (EU Regulation 1253/2014). Compliance assessments cover both the energy performance of heat recovery and the intrinsic specific fan power (SFPint) under the nominal operating conditions declared by the manufacturer.
