The key role of synthetic ester base oil in the formulation of refrigeration oil

High compatibility with new refrigerants

Synthetic ester base oils have a polar structure and exhibit excellent solubility and compatibility with mainstream HFC and HFO refrigerants such as R134a, R404A, R407C, R410A, etc.Ensure the smooth circulation of oil along with the refrigerant, improve the oil return performance, avoid oil shortage in the compressor, and reduce the operational fluctuations and failure risks of the system.

Outstanding lubrication and anti-wear protection capabilities:

Synthetic ester molecules have natural polarity and a strong adsorption capacity for metal surfaces, which can form a stable and continuous lubricating oil film inside the compressor.Reduce friction and wear, minimize damage to bearings, rotors and piston components, and extend the service life of the compressor. Even under high-load or frequent start-stop conditions, synthetic esters can still provide reliable lubrication protection.
