The wall-mounted heat recovery unit aRheat is designed for continuous and controlled ventilation with heat recovery, ensuring a supply of fresh air with minimal thermal losses. It features an axial fan and a ceramic heat exchanger, allowing efficient exchange of air between the interior and exterior. The device operates in three modes:

• Exhaust air operation
• Supply air operation
• Heat recovery mode, with a cycle of 65 seconds, during which exhaust and supply air are alternated, recovering heat from the outgoing air

aRheat is ideal for apartments, hotels, cafes, as well as other residential and public buildings, improving indoor air quality and energy efficiency. It is designed for wall mounting, with a telescopic design that allows installation on walls with thicknesses from 270 mm to 500 mm. The fan is powered via a cable with a 90 cm plug and is easily controlled with a remote control. The aRheat 125 version is equipped with an automatic flap that protects against the backflow of cold and humid air into the space. The flap closes automatically about 3 minutes after the fan is turned off. Additionally, it features an integrated humidistat that — when activated — automatically increases the fan speed when humidity levels rise (50%, 60%, or 70%). Key Features:
