ClimaDry
®
II Application Considerations
The reheat coil adds a small amount of resistance to the air stream.
Consult the correction tables in this manual for details.
Unlike most hot gas reheat options, the ClimaDry
®
II option will
operate over a wide range of EWTs. Special fl ow regulation (water
regulating valve) is not required for low EWT conditions.
Water-Source Heat Pumps with ClimaDry
®
II should not be
used as make-up air units. These applications require equipment
specifi cally designed for make-up air.
Consult ClimaDry
®
II AOM for more details and unit availability.
Modulating reheat valve automatically
adjusts reheat capacity based upon leaving
air temperature and loop entering water
temperature to provide 100% reheat and
“neutral” supply air

Standard DXM control takes input from either a humidistat or
dehumidistat and controls the reheat function by interfacing with the
modulating reheat valve
Reheat coil reheats the cool dehumidifi ed air to
“neutral” supply temperature
Separation between evaporator coil and reheat
coil to allow maximum moisture removal
