The TrueDRY DH90 performs multiple indoor air quality functions in a
single, compact unit:
• High-Capacity Dehumidification
• Fresh Air Ventilation
• Air Filtration
Dehumidification
The TrueDRY DH90 dehumidifier utilizes refrigeration and internal air cir-
culation to cool the incoming air stream below its dew point. This cooled
and drier air is used to pre-cool the incoming air stream resulting in a
significant increase in overall efficiency.
After helping to cool the incoming air, the processed air is reheated by
passing through the condenser coil. The heat removed by the evapora-
tor coil is returned to the air stream, resulting in an overall temperature
increase to the processed air.
The TrueDRY DH90 is controlled by a variety of 24 volt remote wired con-
trols.
Fresh Air Ventilation
Optional fresh outdoor air may be ducted to the unit via a six-inch round
duct. This provides fresh air to dilute pollutants and maintain a normal
oxygen content in the air. The amount of fresh air ventilation can be
regulated by a variety of dampers and controls.
Air Filtration
The TrueDRY DH90 includes a MERV-11 air filter to keep the DH90’s con-
denser coils clean.

Main Return to Main Supply
Ideal when…
• Running TrueDRY DH90 opposite A/C operation.
Running with A/C operation requires damper on the
exhaust port to minimize backdraft when TrueDRY
DH90 is not on but A/C is.
• Minimizing DAT increase is preferred.
• Space dictates.
Ideal when…
• Drying a specific area of the house.
• Running with A/C operation requires backdraft
damper on the exhaust port to minimize backdraft
when TrueDRY DH90 is not on but A/C is.
