It’s all about preventative maintenance, folks. Heat Exchangers, Chillers, Evaporators, Condensers, Generator Fans and Air Exchangers all have cooling coils surrounded by fins that get plugged up over time with dirt and other debris as air moves through them. This causes these expensive machines to work harder and use more energy. A coil fouled with dirt and grime cannot supply proper heat transfer and results in greater energy consumption.
FACTS: Equipment operating with dirty coils can use up to 37% more energy than those with clean coils. Additionally, a dirty system’s cooling capacity can be reduced by as much as 30%. Dirty coils increase operating pressure and temperatures that breakdown the compressor’s lubricant and can result in equipment failure. A failed compressor means no cooling, costly repair and expensive downtime to your operations.
Why do it?
Performing equipment diagnostics, we’ve conducted before and after tests with both air flow and energy usage. The results were a consistent 20% to 30% drop in energy use and up to 100% better air flow immediately after the coils were cleaned! This means the machines are not working as hard, adding life to your equipment and energy savings in your pocket! A coil cleaning program should be instituted when the coils are new, clean, and should be performed with a frequency to prevent deterioration of the coils. This can be as often as four times a year (monthly cleaning is reported in some areas).
