News Releases


MILWAUKEE, WI, October 20, 2021: Desert Aire announces its new GreenAire™ with VPDsync, a complete indoor climate control system with integrated controls and superior, energy-efficient air handler that creates consistent temperature, humidity and vapor pressure deficit for very large indoor agricultural grow facilities of greater than 150,000 sq. ft. to the indoor controlled environment agriculture market.


“In these extra-large facilities, the use of chilled water may be a more economical solution than individual units with compressors,” said Paul Stewart, Vice President of Sales for Desert-Aire LLC. “The GreenAire product is a custom air handler that incorporates internal water flow and temperature control loops to allow the system to vary its sensible heat ratio to meet any load in the grow facility.”

“The key design element is the use of Desert Aire’s special VPDsync™ control algorithms developed for our direct expansion refrigeration based GrowAire product line,” added Keith Coursin, President of Desert Aire. “The GreenAire system will find an air and water flowrate along with a water temperature to match the zone’s load.”


The GreenAire system uses EC type fans for self-balancing airflows using the controller’s output to set the ideal air volume.  A Desert Aire supervised remote start-up can be accomplished utilizing AireGuard, Desert Aire’s cloud-based access system.


Growers will have the indoor climate control they need to maximize yields and improve plant quality to be competitive in the indoor agriculture market using GreenAire with VPDsync™.
