Greenwood Airwood, heat recovery ventilation, MVHR

A specific fan performance of 0.47 W/l/s and 93% heat transfer are achieved by Greenwood Airvac Fusion HRV2HT heat-recovery ventilation units. These units incorporate the company’s Smart technology to simplify commissioning, with the use of a single wireless LCD controller to set up, adjust and commission numerous units on site. Variable airflow settings are ensure that the requirements of Building Regulations are achieved on site first time.

These units sense the outside temperature and adjust the way air is delivered into the dwelling to create the ideal indoor climate all year round.

Another feature enables units to react only to man-made humidity rather than simply to a preset generic setting. The duration of occupancy is also used to determine run time. Both these features eliminate nuisance running noise and reduce energy wastage and heat loss throughout the year.
