All-Aluminum HRV with Explosion-Proof Design
Designed for a waste water treatment plant (WWTP) this XeteX custom Heat Recovery Ventilator (HRV) features an all-aluminum construction with explosion-proof design. It offers safe spark-free operation, equipment longevity, indoor air quality, and energy-efficient climate regulation—all in one unit.

In harsh environment like waste water treatment plants, where the atmosphere commonly contains corrosive and volatile gases, HVAC systems must operate without any risk of sparking. It is crucial that HVAC systems prioritize safety with explosion-proof design; provide adequate ventilation for optimal air quality; and select corrosion-resistant material for long lasting performance.
