DryGair Main Features

Efficient Large-Scale Dehumidification for Horticulture

DryGair provides high water extraction rates, using efficient, condensation-based dehumidification. Designed for optimal performance under greenhouse and grow room conditions.

Patented Air Circulation for Uniform Climate

DryGair’s patented air circulation module and powerful fans spread the treated air in all directions, 360°, to ensure homogenous, optimal climate conditions throughout your growing facility.

DryGair Benefits

Prevent Diseases

Powerful water extraction reduces humidity and prevents condensation. Avoiding humid or wet conditions eliminates the development of humidity related diseases and mildews.

Create Uniform Climate

The patented air circulation module disperses dry air to all corners of the growing space. Air circulation ensures a uniform climate, providing all plants with the best conditions.

Save Energy

DryGair is designed for maximum energy efficiency. Save as much as 50% on energy, compared to traditional humidity control methods.

Success Stories

DryGair provides large-scale growers with efficient humidity control – saving energy and eliminating diseases in various growing facilities and climates around the world, in all types of crops – from vegetables and herbs to flowers and cannabis.


“We use DryGair as a focal point in our cultivation environment designs, by leveraging its dehumidification, high-capacity air distribution, and heating and cooling capabilities. DryGair provides us the assurance that disease-promoting conditions are at bay.”

Golden Leaf Holdings, Cannabis

“DryGair units are a sustainable solution for dehumidification, because of the energy savings and the reuse of water. The energy saving was an important argument for choosing the installation of a second series of ten DryGair units.”

DryGair's Benefits

“There are many benefits to using DryGair. First of all, reducing humidity. Second, is the prevention of wet leaves. When the leaves aren’t wet in the morning, it allows us to maximize our work hours in the greenhouse. We aren’t limited in our use of manpower.

One of the targets we set when we integrated DryGair, is to reduce our environmental impact and pesticide use. Of course, as DryGair does what it’s meant to do, we hardly use pesticides anymore. Rather, we use preventative products, at a significantly lower rate than before.

I forgot to mention energy. Ventilation involves removing high-energy air from the greenhouse and introducing low-energy air. This process is extremely wasteful in terms of energy. DryGair helps us save this energy as well.”
