This is a compressor free dehumidifier which operates without refrigerant.
It has an almost consistent rate of water extraction at all temperatures and
is more efficient than compressor based dehumidifiers when used at low
temperatures below 5°C.
The operation theory exists in the Dehumidify Wheel (a chemically
impregnated rotating wheel). Damp air from the environment is drawn
through the unit where it comes into contact with the wheel. The chemical
on the wheel removes the moisture from the air and warmed by the heating
elements inside.
As the wheel rotates to a different position, the heater drives the water from
the chemical wheel and the water is condensed through heat exchange
system and removed to water tank.
