Air circulation

Why does air circulation matter so much?

Air circulation is used to obtain an even climate and healthy active plants.

With the use of proper circulation, growers can effectively maintain homogenous levels of humidity and temperature, reduce condensation, improve plant transpiration and maintain even growth, while increasing energy efficiency.

Measurement

To efficiently measure the effect of air circulation, it is best to use a proxy, such as temperature, as air movement itself is difficult to measure accurately. In a growing space, multiple microclimates exist simultaneously with differing conditions, making it impractical to gauge using one sensor. To properly measure the homogeneity, and therefore the effectivity of the circulation, it is recommended to use multiple heat sensors or a thermal camera to create a heat map of the entire facility.

DryGair Unique 360° Air Circulation 

DryGair’s dehumidification systems are designed to create optimal air circulation in greenhouses as large as 4,000 m² (40,000 ft²) and treat up to 22,000 m³ (13,000 CFM) of air per hour.

This is achieved through several patented design characteristics:

Greenhouse air circulation creates uniformity humid air from underneath the p-lants

DryGair units suck in humid air from the bottom and release dry and warmer air from the top, thus the dry air slowly descends as it cools, providing humid-controlled air at all heights while focusing mainly on the top level of the plant, where growth occurs.

360 air circulation drygair greenhouse dehumidifierThe roof of the DryGair unit has been specially designed and honed to distribute the outgoing air evenly in all directions. This feature, combined with the built-in fans, allows the dry air to travel along with the thermal screen, to reach all corners of the greenhouse.

These two features combined ensure air flow from top to bottom, in an inward motion towards the unit in the center of the greenhouse.

Benefits of DryGair’s air circulation:

– Air uniformity throughout the greenhouse

– Additional fanning allows for energy savings

– Circulation at all heights including amidst the foliage

– Large air capacity

DryGair systems may create air circulation with or without turning on the dehumidifier, allowing for optimal circulation at times where dehumidification is not necessary
