Total Energy Recovery Up to 30,000 cfm
XeteX total energy recovery units are available up to 30,000 cfm with a non-sectioned heat wheel. This unit uses two backward inclined airfoil plenum blowers in each airstream to supply 29,150 cfm of air to a school. A hot water preheat coil is used in the supply air upstream of the heat exchanger so that the wheel can keep operating even when the outdoor temperature is well below freezing. With another hot water coil and premium efficiency blower motors, this unit provides fresh outdoor air ventilation and heating while also cutting building operating costs.
