Commercial Greenhouse Dehumidifiers

Save up to 50% of energy costs with a dehumidifier

DryGair: Greenhouse dehumidifiers

The greenhouse climate determines the quality of the crop. A stable climate with no temperature changes and high humidity results in better crops. Due to crop evaporation, the humidity in greenhouses is often too high. DryGair is a greenhouse dehumidifier that is the perfect solution to your problem! DryGair units dehumidify the air in the greenhouse. This reduces the humidity and increases the moisture deficit. You get a stable greenhouse climate, resulting in higher yields. Did you know that the DryGair unit helps you save energy? Instead of releasing the energy in the water vapour to the outside, it is retained in the unit's cold panels. This not only prevents energy loss, but also saves up to 50% energy!

Increased yield 

Less use of crop protection products  

No reduction in CO2 due to closed windows 

Less trouble from algae growth due to dryer conditions

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.

DryGair dehumidifier technique 

  1. The DryGair air unit will be placed inside the greenhouse.
  2. Only one electrical connection is required.
  3. The power used is 10 KW.
  4. No additional hot water supply.
  5. The unit sucks relatively humid air.
  6. The air is dried inside the unit.  
  7. The unit drains 45 liters of water per hour.
  8. One unit is suitable for max. 5000 m2.
  9. Drained water can be reused.

DryGair units at Jac. Oudijk in Moerkapelle

Wilco Westerman, Head of Technical Services at gerbera nursery 
"The DryGair units treat greenhouse air during cultivation without using outside air. All energy remains in the greenhouse; we do not lose any heat. This efficient way of dehumidifying the air saves 40% on our gas consumption". According to Wilco Westerman, head of the technical department at gerbera nursery Jac. Oudijk in Moerkapelle.

A healthier crop due greenhouse dehumidifier 

Traditionally, people start heating and airing to remove excess moisture from the air. But heating with the windows open costs energy! The DryGair is a plug & play installation that ensures low humidity in the greenhouse. Additional benefits are: Stable humidity and temperature, low disease pressure and lower energy costs. All in all, a healthier crop due to a better climate! Click here to view all DryGair products.

Commercial greenhouse dehumidifier is the solution for decreasing moisture

Marcel Vijverberg, Uses the DryGair units for the humidity in the greenhouse
In March 2016, Marcel Vijverberg installed two DryGair units in an 8,000 m2 greenhouse. During the night, the two units easily remove 800 liters of water. This eliminates the need for heating and ventilation. In addition to the lower energy bill, Vijverberg says he has a healthier crop, a better climate and the plant growth is more compact.
