1.
HR30W and HR100W Heat Recovery Units work under pressure balance, i.e. they supply almost as much air into
a room as they extract.
2.
The twin impeller and heat exchanger
arrangement simultaneously supplies and extracts
air while transferring heat from the stale exhaust
air
fl
ow to the fresh intake air
fl
ow. This provides up
to 70% heat recovery from the stale extracted air.
For situations when the air exchange needs to be
increased immediately, boost mode is available.
3.
Installation and maintenance are identical
for both the unit models (HR30W and HR100W)..
