Energy efficient air dehumidification

The greenhouse climate determines the quality of the crop all year round. An even climate without temperature fluctuations and without excessive humidity results in better crops.

The DryGair units dehumidify the greenhouse air; both the RH and absolute humidity drop, while the moisture deficit increases. Instead of releasing the energy contained in water vapour to the outside, it is "harvested" on the cold panels of the DryGair unit. This does not result in energy loss, but rather in energy savings of up to 50%!

Because of evaporation from crops, humidity in greenhouses is often too high. A classical solution to this is opening the windows, so that cold air can flow inside. The downside of this is however, that the heaters have to keep the temperature levelled, which eventually costs lots of energy and money. The Drygair units are a good solution to this. With Drygair units you can easily and efficiently dehumidify the air inside the greenhouse. Because of this the humidity and temperature inside the greenhouses are more stable.

DryGair DGX launch

Royal Brinkman introduces the DryGair DGX, the newest model in the series of DryGair dehumidifiers. This smaller model is especially designed for indoor crops, small greenhouse units for seed companies, vertical farming and drying units. With the introduction of the DGX, DryGair is providing a controllable greenhouse climate in more and more crops and therefore improving the quality of the crop.  drygair dgx launch



DryGair DGX specifics
The unit is distinguished by its smaller size: 130 x 110 x 160 cm, weighs only 375 kg, has the highest efficiency (l/hour/KWh) in a range of 13-35°C and can be installed either standing or hanging. The unit has a high efficiency in reducing the relative humidity in two working areas, namely 80% RH at 18°C and 60% RH at 26°C. On both sides, the unit is equipped with panels for condensing the greenhouse air, up to a total of 16 liters per hour. This DryGair DGX is also equipped with the patented air circulation system, which makes this unit very suitable for the cultivation of for example tomatoes and peppers. The unit is equipped with the latest technology including a remote control. This makes it possible to optimize the cultivation conditions of your crop from a distance as well.

  • DryGair units at Jac. Oudijk in Moerkapelle

    "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 gerberakwekerij Jac. Oudijk in Moerkapelle.


How does the Drygair work?

The unit is a combination of a dehumidifier and a heater. The used electrical energy and the released heat are both reused in the greenhouse. 

The condensed humid is drained or can even be used as process water. The DryGair units dehumidify the greenhouse air; both the RH and absolute humidity drop, while the moisture deficit increases. Instead of releasing the energy contained in water vapour to the outside, it is "harvested" on the cold panels of the DryGair unit. Besides extracting water from the air, the greenhouse air is further recirculated, which ensures 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 ensures fewer fungal diseases, which reduces the use of pesticides. The DryGair unit can be controlled manually, with the unit switching to a setpoint of its own choice, or automatically via the climate computer.  Drygair working



Drygair Technique
1. The drygair unit will be placed inside the greenhouse.
2. Just an electrical connection is needed.
3. The used power is 10 KW.
4. No additional inflow of hot water.
5. The unit sucks in relatively moist air.
6. Inside the unit the air is dried.
8. The unit drains 45 litres of water per hour.
9. One unit is suited for 5000 m2 max.
10. Drained water can be recycled.






 

A healthier crop due to a better climate

Traditionally, people start heating and venting to remove excessive humidity 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 advantages of this are: Stable humidity and temperature, low disease pressure and lower energy costs. All in all: a healthier crop due to a better climate!
