A KWH data logger was placed on the unit 2 weeks prior to starting the project. At the 2 week point, the unit condenser coil and cabinet on the until were first cleaned. The condenser coil was coated with MicroGuard AD 35 siloxane coating to prevent corrosion and enhance energy efficiency. The exterior cabinet was coated with ThermaCote ceramic coating to protect against corrosion and to provide a radiant barrier against solar heat gain, which reduces load and energy consumption.
Exterior cabinet temperature was reduced from 135⁰F/57.22°C to 92⁰F/33.33°C. KWH data logger continued to collect data for 2 weeks after. Implementation of the coating project on all of the units on the roof had a substantial positive impact on operating costs and the overall bottom line. Savings were achieved through energy consumption KWH, peak demand KW, reduced maintenance cost, reduced mean time to failure, and reduced capital cost replacement budget. Life cycle extension 25 to 50% Reduced maintenance cost, time, mean time to failure Energy Consumption reduced by 24%
