Description
The DEXA HR is a decentralised single-room heat recovery unit that uses alternate-flow technology, switching between supply and extract every 70 seconds. A high-efficiency ceramic heat exchanger captures heat from the extracted air and transfers it to the incoming fresh air, improving indoor air quality while helping to reduce heating costs. Constant airflow tackles condensation and mould, the unit runs extremely quietly, and an easily removable front cover makes filter maintenance simple.
Available in Ø100mm and Ø150mm sizes, the DEXA HR can be fitted as a standalone unit or paired with a second unit for cross-ventilation. Its modern flat fascia suits contemporary interiors, while the reversible EC motor with thermal protection provides energy-efficient continuous operation. Optional humidity and PIR sensors can automatically increase speed on demand, and a free-cooling option with an integral LED indicator adds further flexibility.
