|IceCOLD® contains two (2) synthetic catalysts* and a lubricity agent that enables HVAC / Refrigeration system operate at maximum designed efficiency.
The Lubricity agent increases the lubricity of the compressor oil by 54%, which reduces the internal friction. This allows the compressor operate cooler and quieter.
What is Oil Fouling?
In virtually all air conditioning and refrigeration systems 1/2% to 8% of the compressor’s lubricating oil circulates with the refrigerant. This oil attaches to the inner walls of the refrigeration tubing and acts as an effective insulator to heat exchange. It is these oil deposits that ultimately block heat transfer, and reduce your system efficiency.
Equipment suppliers may state that in a particular system, migrating oil concentration has been reduced to only one percent. The one percent being referred to is one percent of the total oil volume. If a compressor holds four quarts, or 128 ounces of oil, then at one percent, 1.28 ounces is flowing through the system at any given time. Since a capillary tube, oil pressure switch, or expansion valve can be fouled with a few milligrams of oil, when one percent of any oil charge is flowing constantly through the system, the system will become oil-fouled.

Effects on Heat Transfer
Oil-fouling of the heat transfer surfaces of air conditioning and refrigeration systems will cause a loss of about 7% efficiency the first year, 5% the second year, and 2% per year the following years.
According to ASHRAE, performance is degraded by as much as 30% due to build-up of lubricants on internal services. * Higher percentages ages have been observed in systems 20 years old or older.
Managing the Problem
Some of the techniques used by manufacturers to control migrating oil include the use of mechanical devices such as separators, skimmers, drums, heat sources, suction risers, traps and pumps. However, according to ASHRAE’s Handbook*, these high-tech designs are not efficient enough to remove all of the unwanted oil. Although the mechanical solutions may reduce the problems of restricted or plugged capillary tubes or sticky expansion valves, they do not resolve the boundary layer oil fouling over time.
The heat transfer efficiency loss due to oil-fouling is restored to near new equipment levels by using IceCOLD‘s synthetic catalyst to break the Vander Waals (surface tension) forces between the oil globules and the walls of the refrigeration tubing. The absence of oil-fouling restores the lost of 20% to 30% heat transfer efficiency. An added benefit is that the capillary tubes, expansion valves and heat pump’s 4-way valves are also cleaned, and will not oil-foul again.
The result is that IceCOLD® delivers an average financial payback period of under twelve months, and a Return On Investment of up to 500%.
IceCOLD® is easy to install by HVAC technicians certified and trained by Green Ice Technology, without disrupting the system’s operation. There is no “down time” in the systems operation during the installation process.
