Reclaiming HVAC Condensate Water

Overview

Plants in a grow room can transpire hundreds of gallons per dayWater is part of the cost of plant production, whether it's cannabis or micro-greens. By collecting and reclaiming the moisture transpired by plants as condensate from your HVACD equipment, you can conserve considerable amounts of water. An HVAC unit’s condensate water from its evaporator coil can be reclaimed to water the plants in the room it dehumidifies. How much water are we talking about? 

A large Desert Aire GrowAire unit in a grow room application can collect up to 347 lbs of water an hour. In a cannabis flower room, that would result in as much as 500 gallons of water saved per week with mature plants. That’s 71 gallons a day, 500 gallons a week, 26,000 gallons a year or a typical 18’x36’ swimming pool 4- to 8-ft deep. That’s a lot of water!

Desert Aire's superior HVAC system evaporator coil coating means condensate water is less likely to pose a risk to plants due to metals and other chemical contaminants in condensate water that’s reused to water plants.Condensate draining from p trap pipingCannabis plants condensate drain can fill a 18 by 36 foot swimming pool

Desert Aire’s HVAC system evaporator coil coating in grow applications provides superior performance in preventing corrosion and fin deterioration. Our coating is a water-based, low VOC coating process engineered specifically for HVAC/R heat transfer coils.

In the coating process, the entire coil assembly is protected. This includes the coil fins, end plates, copper tubing and copper return bends. The coating covers the entire coil assembly. When properly maintained, you can expect the coated coils to provide protection for years. In addition, Desert Aire provides a 5-year coil parts warranty as evidence of its superior protection.
