Description
The Emkarate family of lubricants is a wide range of polyol ester refrigeration oil products. They are designed specifically for use with HFC refrigerants, developed to meet the performance demands of the refrigeration industry. This superior performance is achieved with basefluids that are specifically formulated to deliver optimum performance with minimal additive levels.

The requirements of today’s refrigeration and air conditioning compressor lubricants are complex. They must be compatible and miscible with the HFC refrigerants, and they must be compatible and miscible with CFC’s and HCFC’s as well as mineral and alkylbenzene oils. Polyol ester lubricants meet these needs, and the EMKARATE RL line is the preferred choice. Working in close collaboration with compressor and system manufacturers, these OEM-approved POE lubricants cover a wide viscosity range from 7 cSt (35-40 SUS) to 220 cSt (1100 SUS) to suit most applications. The lubricants have excellent thermal and chemical stability, and are compatible with a wide range of elastomers, polymeric materials and other materials of construction. Additionally, then higher viscosity index is an indication that their effective viscosity will not change drastically with the wide swings in temperature seen by most typical refrigeration and air conditioning systems. They are the preferred choice for servicing and retrofitting existing equipment as well as for OEM charging.

Critical issues
Additives vs Non-Additives.
An increasing trend is the preference to specify lubricants that do not contain additives, as they are not needed in the majority of cases using properly formulated base lubricants. Experiences such as decreased lubricant stability, sludge formation, and component deposits, are concerns related to the use of additives. At the same time, it is understood that additives can also enhance performance in certain particularly demanding applications may be necessary.

Miscibility.
Since some lubricant will travel with the refrigerant in any air conditioning or refrigeration system,
it is imperative that they be fully miscible and soluble with one another…at all temperatures that the system will experience. This insures good oil return and lubricity to the compressor, and no blockage or loss of heat transfer in the evaporator. In traditional systems, the CFC or HCFC refrigerant is miscible and soluble with the mineral or alkylbenzene oil. On the other hand, if these oils and an
HFC refrigerant are mixed, they are mutually immiscible and essentially insoluble. They will separate into two distinct phases in the evaporator and the oil will coat the inside of the tubes, resulting in a loss of heat transfer and potentially a lack of lubrication in the compressor. HFC refrigerants and POE lubricants are fully miscible and have high mutual solubility. As a result, POE lubricants are the proper choice when using HFC refrigerants.
