Airflow Developments says its new Duplexvent Rotary ‘represents a significant advancement in the compact construction of a high performance mechanical ventilation with heat recovery system’.
The range utilises a rotary thermal wheel principle to allow for up to 85 per cent heat recovery, and the delivery of air volumes from 8,000 to 16,000 m³/hr. All units comply with the latest ErP Regulations.
The Duplexvent Rotary Wheel Ventilation with Heat Recovery system is the latest addition to Airflow’s established Duplexvent range. Each unit houses a thermal wheel, which rotates. Heat is picked up from the exhaust air stream in the top half of the rotation, and given up to the fresh air stream in the bottom half – creating a higher air flow through the unit, despite a more concise space.
Available in rooftop or indoor versions, the units are delivered in three parts. They can be customised with a choice of duct orientations where supply and extract ports can be rotated by up to 90 degrees to allow connections to be installed within the demands of the building’s size and layout.
Quiet in operation, the units provide ‘significant energy savings’ through their EC fans. They have a double-skin construction, with high performance 45 mm mineral wool with thermal bridging to class T2, and a heat bridge factor of TB2. They are also fitted with anti- cross-contamination technology.
