PHRV(R) Series
PHRV 140, PHRVR 155 & PHRVR 205
Introducing the PHRV(R) series of Heat Recovery Ventilators
(HRV) by Powrmatic. Incoming fresh outdoor air is filtered
before it is heated by the stale outgoing air through a
polypropylene heat recovery core. The HRV then distributes
the preheated fresh filtered air throughout the home by
direct ductwork installed specifically for the HRV or through
the ductwork of a forced-air system.

DEFROST A preset 5 minute defrost sequence is activated at
an outdoor air temperature of 23ÞF (-5ÞC) and lower.
During the PHRV 140 defrost sequence, the supply blower
shuts down & the exhaust blower switches into high speed
to maximize the effectiveness of the defrost strategy.
During the PHRVR Series (PHRVR 155 & PHRVR 205)
defrost sequence, its mechanism uses a motorized damper
to temporarily block the incoming fresh air stream allowing
the warm air from the home to circulate through the HRV.
The exhaust blower shuts down & the supply blower
switches into high speed to maximize the effectiveness of
the defrost strategy.
The unit then returns to normal operation for 25 minutes,
and continues cycle.
SERVICEABILITY Core, filters, motors and drain pan can be
easily serviced through latched access door.
