Air Conditioning Retrofit at the Neenah Post Office.
First photo is of two inefficient 30 ton Air Conditioning Condenser plate style heat exchangers that were leaking refrigerant, and restricted water flow causing high compressor amperage and poor performance.
The other 3 pics are of the replacement coils in operation. Two 30 Ton Coax Coil Heat exchangers. Reduced the Air Conditioning operating energy consumption by 35%.
