3. UNIT OVERVIEW
The DryGair dehumidifying unit is designed and manufactured by DryGair
Energies Ltd. The unit is designed for the dehumidification of greenhouses
and can also be used in any other closed structure.
The unit reduces the humidity in the greenhouse according to a defined set-
point by pulling the wet cold air from the bottom of the greenhouse,
extracting the water, heating the air, and blowing the drier and warmer air
back into the greenhouse through an air distribution module.
The unit can also be configured to heat or cool the dried air.
The water condensed during the dehumidification process is removed from
the greenhouse through water drainage and can be reused for other purposes
such as a hydroponic system.
3.1 Standard Features
The standard unit includes the following features:
• Humidification Set-Point – ensures the humidity in the greenhouse is

temperature reaches 6°C.
