Super Efficient Energy Recovery for School Ventilation

This unit and two similar ones were built to control humidity in a locker room, restroom, and janitorial room for a school in Maine. The compact design allowed them to all be easily fit into very small mechanical rooms. The prepackaged controls and electrical equipment were designed to use standard 120 V power, making it plug-in-ready on delivery. During winter, the flat plate heat exchanger is able to recover 62% of the energy in the leaving exhaust air, making it as economical in operation as it is in initial investment.
