As most facilities, maintenance and service engineers know – “Going Green” without “breaking the bank” typically requires stepping-up maintenance practices on existing equipment and replacing old equipment only when it can no longer provide the efficiency needed even under the best of maintenance practices. But replacing old machines with new energy efficient equipment doesn’t guarantee you will realize the full efficiency benefit if your maintenance practices don’t prevent fouling of the condenser coils. Note: the term “prevent fouling” is used to distinguish it from the notion that traditional maintenance methods allow coils to go from clean to dirty or, said another way “go from efficient to inefficient” between cleanings vs. practices that protect the coils from fouling in the first place.

Said a different way – if you don’t protect condenser coils on high efficiency systems, they will not deliver the promise of lower energy cost and optimal efficiency. By Randy Simmons
