Dirty Coils Waste Energy and Cost Money

HVAC Coil Cleaning: 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.

“I was having issues with a blocked heating coil in my facility, and I even got as far as getting a $52,000 quote to get this coil replaced. Then I stumbled on Scrub Zero’s web page, I gave Bryan a call and two days later I had Scrub Zero on site and the results were UNBELIEVEABLE. I have brought Scrub Zero back twice since then to help out with other heating coils in my facility. One question to anyone reading this: How clean are your coils? I thought mine were clean, until Scrub Zero paid me a visit. They were well worth the time and money.”

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.

Preventative Maintenance Pays For Itself

The best course of action is to clean them regularly. Conventional methods include pressure washing, compressed air, chemical sprays and disassembly. These methods can be either ineffective, can damage the equipment, are environmentally unfriendly, labour intensive and/or cost prohibitive.

Dry ice blast cleaning solves these problems!

The Process

Dry ice is scooped into our portable units in pellet form. Using compressed air, it is sprayed through the effected coils. As the dry ice hits the surface, it changes directly from a solid to a gas. In doing so, the molecules expand by 800 times the size they were in solid form. The result is an instant removal of the blockage in these coils with no mess or damage to the fins, while sanitizing the surface. Dry ice is moisture free (see Learning Library), so it is non-conductive. Our technicians are experts in ensuring the delicate fins surrounding the coils are not damaged.

How Do You Know It Works?

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).

Why Choose Scrub Zero Ice Blasting?

Since 2005, we have provided mobile dry ice blast cleaning services and have not strayed from our focus in becoming experts in our field. Unlike other service companies, where C02 cleaning is an add-on, this is ALL we do. Our technicians are experts in using the latest equipment the technology has to offer for the industries we serve.

In addition to Scrub Zero being SECOR certified, our technicians are fully certified in all safety courses necessary for working in any environment. This includes various types of manufacturing facilities, including H2S Gas Plants. We are also Canqual Approved and ISNetworld Certified.

There are other applications in gas plants where dry ice blasting makes sense. Remember: NO chemicals, NO secondary waste/mess, NO drying time, and equipment can be cleaned onsite.
