Dehumidifier Rental
Aggreko offers two methods of industrial air
dehumidification: refrigerative drying or desiccant drying.
Refrigerative Dehumidifiers
Refrigerative drying works best with a strong
temperature differential, which means that refrigerative
dehumidifier rental units are most effective at high ambient
temperatures and high humidity. Their effectiveness may be
significantly reduced in colder climates.
A refrigerative dehumidifier is simply an air conditioner with
both hot and cold coils in the same unit. A fan draws the
room's air over the cold coils to condense the moisture, then moves
the air through the hot coils to heat it to its original
temperature. For larger applications, Aggreko has a wide
range of air conditioners and heaters to provide the right
refrigerated dehumidification package.
Desiccant Dehumidifiers
Aggreko also offers desiccant dehumidifier
rental units, which are custom-manufactured with an internal
silica-gel wheel. This wheel simultaneously absorbs water vapor in
one section of the wheel, while the silicate is being regenerated
(dewatered) in another section. When available electrical power is
limited, these dehumidifier rental units can be engineered to
be regenerated by heating with natural gas, propane, or steam.
These dehumidifier rental
units have been successfully applied in numerous applications
including:
- Manufacturing and construction, for reducing the drying time of
wet concrete, speeding up painting and coating operations, or
minimizing corrosion,
- Process applications, such as stabilizing or preserving food
products,
- Restoration of buildings and manufacturing facilities after
flood damage.
