DOAS with Coated HX and Explosion Proof EA Motor
This XeteX project features a custom heat recovery ventilator for a waste water treatment plant located at one of the most exclusive lifestyle estates in the world. The facility repurposes treated water to make snow for the ski slopes and water the golf course greens.
This custom DOAS features an aluminum, epoxy-coated flat plate heat exchanger that offers energy recovery as well as no cross contamination. Premium MERV filtration at the OA and RA improve indoor air quality.
The exhaust air fan includes an explosion-proof motor for safety and non-corrosive material has been selected for long life.
