How does DryGair dehumidifier work?
Our DryGair specialist Hans Belt explains
DryGair units are a combination of a dehumidifier and a heater, making them a perfect commercial greenhouse dehumidifier. The electrical energy used and the heat released are both reused in the greenhouse. The condensed moisture is drained or can be used as process water. DryGair units dehumidify the greenhouse air; the relative and absolute humidity decreases while the moisture deficit increases. Instead of releasing the energy contained in the water vapor to the outside, it is "harvested" on the cold panels of the DryGair unit. In addition to removing water from the air, the air in the greenhouse is recirculated to maintain a uniform climate and an active crop. The water from the unit is collected and can be reused in the process water. The active climate results in fewer fungal diseases, which reduces the use of pesticides. The DryGair unit can be controlled manually, with the unit switching to a setpoint of it's own choice, or automatically via the climate computer.
