Ventilation with heat recovery

02 September, 2007

Ventilation with heat recovery from 220 to 12 000 m3/h is provided by Airflow’s Duplexvent units.

Airflow’s Duplexvent range of compact, commercial unit ventilators with heat recovery use counterflow heat-exchanger technology to achieve a recovery efficiency of 80%. These unit ventilators are designed to provide comfort ventilation and warm-air heating for offices, schools, sports halls, small production and process areas, restaurants and many other commercial buildings. Duplexvent units are available in sizes from 220 to 12 000 m3/h, with control options to regulate air flow as demand varies. Units are available with electronically commutated motors, offering savings compared to conventional AC motors and closer control of air flow. In summer, Duplexvent can assist with cooling by using the bypass mode to isolate the warm-air input into the heat exchanger while filtering the input air. A range of filters is offered, ranging from removing airborne particles to higher-density versions to suit clinical and clean-room installations. Roof-top versions with double insulation and frost and weather protection are available for outdoor applications.
