About Polyester 68

POE68 isa high-quality, syntheticPolyol Ester (POE)refrigeration oil with a viscosity grade of 68, used in air conditioning (AC) and refrigeration systems, known for excellent stability, lubrication, compatibility with HFC/HCFC refrigerants (like R-134a, R-404A, R-410A), and effective wear protection, featuring low moisture content, good low-temp performance, and crucial miscibility with refrigerants to maintain system efficiency.

Key Characteristics & Benefits:

Type:Synthetic Polyol Ester (POE).
Viscosity:Grade 68, offering better lubrication than lower-viscosity POE oils, ideal for compressors with higher discharge temperatures.
Refrigerant Compatibility:Works well with HFCs, HCFCs, and blends like R-12, R-134a, R-22, R-404a, R-410a, R-507, and R-508B.
Performance:Provides superior chemical & thermal stability, strong anti-wear properties, and excellent film strength.
Moisture & Corrosion:Low moisture content, but POE oils are hygroscopic (absorb water), requiring careful handling; it helps prevent acid formation and corrosion.
System Efficiency:Ensures oil-refrigerant miscibility, preventing blockages and maintaining evaporator efficiency.

Common Applications:

Reciprocating and rotary compressors in automotive and general refrigeration/AC systems.
Systems requiring high thermal stability and wide temperature range performance.

Important Consideration:

Hygroscopic Nature:POE oils readily absorb moisture; systems must be properly evacuated, and oil should be protected from air to prevent contamination, which degrades lubrication
