oil-fouling

What causes Oil-Fouling?

  • Oil escapes from the compressor(s)
  • The oil mixes with the refrigerant.
  • The refrigerant and oil are circulated through the coil system.
  • Oil bonds to the coil surface, forming growing deposits that impede heat transfer.
  • The oil deposits also increase drag, making the compressor work harder.
  • The oil buildup eventually coats the entire inside surface of the coil, resulting in ongoing and worsening efficiency loss, along with reduced longevity.

Oil-Fouling can leave units operating at 70% or less of their operating efficiency

The American Society of Heating, Refrigeration and Air-Conditioning Engineers has studied Oil-Fouling for decades

According to ASHRAE, oil-fouling of the heat transfer surfaces for AC and refrigeration systems results in 7% efficiency loss in the first year, followed by 5% in the second year, and 2% annually thereafter. (Included reference).

Here's why... As equipment ages, small amounts of the oil used to lubricate the compressor slowly migrate into the system's heat exchanger coils. This oil-fouling forms a boundary layer that reduces heat transfer efficiency.

Oil-fouling is unavoidable and over time, it causes the equipment to become less efficient, leading to higher energy costs and increased emissions. It also forces the equipment to work harder and run longer which leads to increased repair costs, lower capacity, and premature replacement. Plus, when equipment runs longer, energy costs rise along with greenhouse gas emissions.

ASHRAE states that while mechanical solutions may reduce some problems, even advanced mechanical solutions can't eliminate oil buildup. Furthermore, until recently, no viable, cost-effective solution has been available to treat oil-fouling.

With ONE treatment, the problem is solved for good

If oil build-up is like cholesterol in your HVAC/R system’s arteries, ThermaClear® is the cholesterol-clearing pill that makes everything run smoothly again. And, better than a pill, you only need to apply ThermaClear® once – a single treatment lasts for the lifespan of your system.
