Our IceCOLD® technology was developed in 1986 to remove what ASHRAE (American Society of Heating and Air Conditioning Engineers) calls “compressor oil fouling” from the inner walls of air conditioning refrigeration tubing. The US DOE (Department of Energy) called this original technology “PROA” (Polarized Refrigerant Oil Additive). Please see the ASHRAE “oil fouling” paper with footnotes.

During normal operation, AC / refrigeration systems circulate 1/2% to 8% of their compressor oil with the refrigerant. This compressor oil gradually forms an “oil fouling” layer of compressor oil on the insides of the refrigeration tubing which acts as an effective insulator to the heat transfer that is necessary for the refrigerant to cool the space it is intended to cool. Our technology removes the “ASHRAE” compressor oil fouling permanently from the walls of the refrigeration tubing for the life of the equipment.

This technology was upgraded further to be environmentally friendly in 1996 and was offered to the Fortune 100 from 1996 to 2001 and in 2002 became available to the general market.

In 2002, the technology was upgraded again to be compatible with all synthetic compressor oils and to be more aggressive and environmentally friendly, with state of the art lubricity agents to extend the life of refrigeration compressors.

Since 2001, US Refrigeration Technologies has completed numerous installations with an average electricity cost savings of 23%. Many customers have instrumented their own equipment and calculated the savings themselves. For example, Baylor Hospital in Dallas shows over a 24% electricity savings after installation in their laundry facility. Spring Hill Hospital in Mobile, Alabama shows a 24% electricity savings in their 8 operating rooms. Similar savings are seen at nursing homes, computer rooms, the 277 room Fairfield Grand Desert Resort, Flagler School District, large dairy operations walk in coolers and apartment complexes all with significant electricity cost savings and higher cooling capacity.

The technology also has been verified by a Certified Thermal Testing Lab under the auspices of the Federal Oak Ridge National Laboratory using the ARI (American Refrigeration Institute) EER (Energy Efficiency Rating) testing that is used to rate the efficiency of refrigeration equipment. In this test, the EER of a typical used GE heat pump was raised from 9.0 to 11.3; over 20%.

The NIST (US Federal Government National Institute of Standards and Technology) completed evaluating the technology in June 2004 and concluded that “The heat transfer data show that the additive caused an average enhancement of the R134a/POE heat flux of approximately 73 %”; and “additive can form a monolayer between the wall and the lubricant/additive excess layer”

Chillers, AC package units, PTACs, DX systems and walk-in and mobile refrigeration and freezer units can be treated with a cost effective payback of about a year and ROI of up to 600% and higher.

Besides AC / refrigeration electricity cost savings of up to 23%, savings on annual equipment maintenance and replacement cost will be over 20% since the equipment is running 20% + less.

Some customers are concerned mostly with making their space colder. Such is the case with hospital operating rooms and computer rooms where cooler temperatures are needed without adding more expensive AC equipment.

We encourage you to evaluate installation of the technology throughout your facilities; the electricity and maintenance operating cost savings will be substantial during the life of the equipment. Note that we have a money back performance guarantee of 10% cost savings on AC electrical usage.

Our analysts are available to calculate the costs and associated savings with installing our technology. We will also provide a free calculation of your continued electrical expenses; and recommendations to minimize electricity use and cost without diminishing service.
