By evaporation of crop , the air humidity in the greenhouse often too high. A classic solution to this opening of the windows by allowing cold air to the inside. The disadvantage is that the heat to keep the temperature back on track and end up costing this much energy and money. The solution is Drygair units. With Drygair units , the air in the greenhouse dehumidification in an efficient and simple way. As a result, the humidity and temperature stable.

The unit is a combination of a heater and a dehumidifier . The electric energy and heat released both come back into the greenhouse. The condensed moisture is discharged , or may even be used as process water.
