RL-5500 Series

The CPTEC® RL-5500 Series oils are synthetic polyol ester (POE) lubricants formulated specifically for use in refrigeration and air-conditioning compressors using HFC refrigerants. This products provide effective wear protection for steel and aluminum surfaces for increased system life and improved efficiency and is suitable for both initial fill and service fill. The combination of low temperature characteristics and unparalleled chemical and thermal stability enable the use of CPTEC RL-5500 Series over a wide operating temperature range.

    Expert lubricant selection needed

    Specialty gas compressor lubricants work in direct contact with gas stream and may be diluted with gas or contaminated with some gaseous or liquid media. This would alter lubricant properties. For proper lubricant selection we need to perform calculations with gas dilution and contamination in mind.
