Energy Recovery Series


System Operation

Air2O ER systems use Evaporative Heat Recovery (the term we use when we employ direct evaporative cooling in the exhaust air stream).

Return air is cooled adiabatically by means of a direct evaporative cooling pad. The water utilized is cooled to within approximately 0.5°c of the return air wet bulb temperature.

This cool water is then transferred to the high efficiency heat exchanger facing the intake (outdoor) air.

The high Delta T this creates provides higher heat transfer and higher energy recovery with only 50% of the Static pressure of a traditional Thermal wheel approach.

The result of this innovative approach to thermal energy recovery means Air2O ER systems are at least twice as effective as thermal wheels and the highest performing evaporative recovery system in the world today.
