A premier brand of lubricant manufactured by CPI Fluid Engineering, Emkarate RL offers synthetic polyol ester (POE) lubricants formulated for refrigeration and air conditioning compressors that use hydrofluorocarbon (HFC) refrigerants.
These oils offer advanced wear protection, enhanced miscibility with refrigerants and greater thermal stability compared to mineral oils. This makes them an excellent match for systems where high efficiency is essential.
What is POE oil?
A fully synthetic solution, POE oil is a compressor lubricant that has been engineered to work with specific refrigerants that do not combine correctly with conventional mineral oils.
These HFC refrigerants are defined as synthetic fluorinated gases that, while known for causing zero ozone depletion, have high global warming potential (GWP). Examples include R507, R410A, R407C, R404A and R134A.
Miscible with refrigerants once combined, POE oils like those in the Emkarate RL series let the lubricant circulate the cooling system’s moving parts and then return to the refrigeration air compressor. This continuous circulation ensures the compressor's parts keep cool and lubricated and its valves and piston rings stay sealed.
Typical applications for Emkarate POE oils
The Emkarate RL range’s oils are used in a wide range of applications. They serve commercial refrigeration compressors and refrigeration systems used in supermarkets.
The POE oils also help maintain and protect air conditioning compressors and cooling systems used in transport refrigeration systems and industrial refrigeration plants.
What are the most common Emkarate oil grades?
To suit different compressor designs and applications, various viscosity grades are offered in the Emkarate RL series.
Numbers featured in product names correspond to their ISO grade to indicate viscosity.
Emkarate RL32H is commonly used in scroll compressors and air conditioning systems, while Emkarate RL68H is used widely in the commercial refrigeration sector. A heavy-duty oil, Emkarate RL100H is engineered for use in larger compressors.
Key properties of POE Oils outlined
To sum up, POE oils have a synthetic polyol ester base and have exceptional miscibility with HFC type refrigerants. Under high pressure, they offer good lubrication and have both high chemical and thermal stability. Additionally, they have strong moisture absorption properties.
