Airow is controlled within +/- 5% up to Max ESP shown with wet coil and standard 1” berglass lter.
ClimaDry II equipped units are factory set to operate in stage 2 airow.
HZ Series with ClimaDry II
All HZ units have an ECM fan motor. The small amount of
additional pressure drop of the ClimaDry II coil causes the ECM
motor to slightly increase RPM to overcome the added pressure
drop and maintain selected CFM up to the maximum ESP.
