Puraman R110E POE – Frequently Asked Questions (FAQ)

Q1: What is Puraman R110E POE and how does it differ from conventional mineral oil-based lubricants?

A: Puraman R110E POE is a polyolester (POE) synthetic lubricant specifically engineered for use in modern refrigeration and air-conditioning systems employing HFC, HFO, and next-generation low-GWP refrigerants. Unlike mineral oils, it offers superior miscibility with polar refrigerants, enhanced thermal and oxidative stability, and improved low-temperature fluidity—making it suitable for demanding variable-speed and low-charge applications.

Q2: Is Puraman R110E POE compatible with common elastomers and sealing materials used in HVACR equipment?

A: Yes, Puraman R110E POE demonstrates good compatibility with standard HVACR elastomers including nitrile rubber (NBR), hydrogenated nitrile rubber (HNBR), and ethylene propylene diene monomer (EPDM). Compatibility testing under actual operating conditions is recommended when integrating into new or retrofitted systems, especially with specialty polymers or aged seals.

Q3: Can Puraman R110E POE be mixed with other POE lubricants or residual mineral oil in a system?

A: While Puraman R110E POE is miscible with most commercial POE lubricants, intentional blending is not recommended without prior compatibility and performance validation. Traces of mineral oil may remain after proper system evacuation and flushing, but full replacement is strongly advised to ensure optimal refrigerant miscibility, moisture control, and long-term compressor reliability.

Q4: What are the key handling and storage recommendations for Puraman R110E POE?

A: Puraman R110E POE is hygroscopic and must be protected from atmospheric moisture at all times. Store in original sealed containers in a clean, dry, temperature-controlled environment. Use dedicated, dry handling equipment; avoid prolonged exposure to ambient air during dispensing. Always follow good industrial hygiene practices and consult the Safety Data Sheet (SDS) before use.
