The benefit of clean condensing and cooling hvac coils is an increase in their efficiency by 15%-30% depending on what research paper you read. The problem with most of these coils is they are difficult to get at or inside the AHU and require shutting the system down – which may not be a viable option.
With Cottonwood soon to be the white stuff in the air we are all concerned about and cooling season fast approaching in our goofy climate the Spring PM schedule usually involves an inspection and cleaning of these critical components. Though it may be nice to get up on the roof on a sunny 50 degree Spring day after being stuck inside all Winter there are usually more important things on the PM list during the change-over season.
“But we can’t just skip cleaning the coils!” And we’re not suggesting you do that, but there is some simple cost-effective technology available to you now that can significantly reduce the time it takes to clean coils or even eliminate the build-up on the coil that gets them dirty in the first place. Whether you maintain a large AHU, some rooftops, a large cooling tower, or air-cooled chillers there are solutions that can help your equipment operate at system design year-round by keeping the coils clean without constant maintenance
