2. Maintain IAQ with Energy Recovery Ventilators (ERVs) More @ www.drirotors.com A ENTERPRISE Visit us at www.bryair.com.my WHAT IS AN ERV? An energy recovery ventilator (ERV) is a type of mechanical equipment that features a heat exchanger combined with a ventilation system for providing controlled ventilation into a building.

3. Maintain IAQ with Energy Recovery Ventilators (ERVs) More @ www.drirotors.com A ENTERPRISE Visit us at www.bryair.com.my HOW DOES AN ERV WORK? An ERV, exchanges the contaminated room air with fresh outdoor air, in the process recovering more than 65% of the energy from the exhaust air stream. The energy recovery wheel slowly rotates (@ 20 RPM) between the two counter flowing exhaust and supply air streams pickings up the sensible and latent heat from the cooler air stream and transferring to the warmer air stream or vice versa depending on the conditions. The energy recovery ventilator consists of two blowers and a energy recovery wheel. The two blowers run continuously to exhaust the room air and replace it with an equal amount of fresh outdoor air.
