Save Compressed Air

What is IceCOLD® ?
IceCOLD® is a scientifically engineered synthetic catalyst designed to restore lost efficiencies in all HVAC and refrigeration systems by eliminating what ASHRAE defines as oil fouling.
What is Oil Fouling ?
American Society of Heating Refrigeration and Air Conditioning Engineers

ASHRAE states that .5 to 8% of the compressor oil circulates through the coils of an air conditioning or refrigeration system and the oil will stick to the inner walls of the refrigeration coils, creating a layer of Oil Fouling, which is about 2% of the diameter of the tubing. This oil fouling layer creates an additional medium of heat exchange which reduces efficiency.
HVAC and Refrigeration Systems
Chillers
A chiller is a system where water (or glycol or saltwater brine) is cooled, not the air. Unlike air cooling, water is used as the heat conductor. Water (brine) or Glycol (antifreeze) is circulated, instead of air, to cool a space or object. Water is cooled in a “barrel” with the evaporator refrigeration coils running through it.
The cooled or chilled water is pumped to a heat exchanger or “radiator” in the space to be cooled. A fan blows over the radiator, containing the chilled water, which cools the air. The chiller system is more efficient than an air system since water carries more heat per unit space, then air. The water is cooled to 42 48 degrees F and then returned from the radiator to the chiller barrel for re cooling. It is returned to the radiator again and again to cool the designated space.
Chillers can have reciprocating, screw, or centrifugal compressors. For all chiller applications it is critical to confirm the compressor type, refrigerant type, and oil separator type to determine the blend and quantity of IceCOLD® that should be used.
Compressor Systems
Centrifugal Compressors can contain a separate oil circuit and no DX valve. In this case we add IceCOLD® Centrifugal Blend to the refrigerant circuit at .3 ounces per ton. We separately add IceCOLD® Lubricity Blend, to the oil circuit at 2% of the manufacturers stated oil charge. It is an industry known fact that oil fouling occurs from oil intruding into the refrigerant circuit over time through leaky seals. This makes Catalyst 1 effective in removing oil fouling. Catalyst 2 reacts as it passes through the DX valve which is nonexistent in these systems.
The IceCOLD® Standard Blend is compatible with Rotary (screw) compressors provided that there is not a Coalescing Oil Separator. Coalescing Oil Separators are generally a horizontally mounted cylinder. On Rotary (screw) compressors that do not have a coalescing oil separator, IceCOLD® Standard Blend is added to the refrigeration circuit at 10% of the manufacturers stated oil charge.
CENTRIFUGAL
A centrifugal compressor model number will normally be located on the front or side of the control panel. The refrigerant type and overall tonnage of the unit is also required for centrifugals and can usually be obtained by asking the on site technician or maintenance personnel if not listed on the control panel.
SCREW
A screw compressor’s information will normally be located on the control panel, or on the actual compressor itself. Tonnage is not a requirement for screw compressors; however, refrigerant type must be noted. We never install IceCOLD® in ammonia refrigerant with screw compressors.
