Vent Axia 370450 HR500D Commercial Ducted Heat Recovery Unit

The HR500D is a powerful heat recovery unit designed for use in commercial situations such as offices, server rooms and class rooms. It offers up to 70% Heat Recovery, using a heat cube which interleaves outgoing warm air with incoming cool air without mixing the two air streams. The heat cube itself uses no power at all - drawing heat only from the outgoing air.

The HR500D extracts stale or moist air at a rate of 174L/s. Using different sized spigot sets, sold separately, the HR500D may be fitted onto 200mm, 250mm or 315mm ducting systems.
