CENTRALISED HEAT RECOVERY UNIT

Whole-house heat recovery unit, suitable for ceiling or false-ceiling installation, for horizontal mounting.

APPLICATION

Whole-house heat recovery unit, suitable for ceiling or false-ceiling installation, for horizontal mounting.

SPECIFICATION

Outer fan casing manufactured from powder coated galvanised sheet steel providing long lasting and robust construction. The unit is finished in white RAL 9010.

Internal structure manufactured from EPP (expanded polypropylene) providing reduced sound emissions and maximised air tightness and thermal insulation.

EC external rotor motors fitted as standard for energy saving. Provided with integral thermal protection, mounted on sealed for life ball bearings.

Backward curved centrifugal impeller dynamically balanced and directly driven by the motor to provide a smooth airflow through the unit.

Highly efficient counterflow heat exchanger to maximise thermal recovery.

 

FEATURES & BENEFITS

Easy installation: 243mm height (269mm including mounting brackets and condensate drains) for installation in low-ceiling spaces.

Simplified electrical connection: the unit is supplied pre-wired.

ISO Coarse 60% (G4) filters are included, easily removable from the outside: no need to remove the access panel for maintenance. ISO ePM1 60% (F7) filter available upon request.

Integrated automatic physical bypass ideal for free-cooling operation during the summer season.

Automatic anti-freeze protection to prevent ice formation on the exhaust side of the exchanger.
