Introduction

​

SynCold® AB series lubricants are synthetic alkylbenzene refrigeration compressor oil specifically developed for commercial, industrial refrigeration and air conditioning compressors.  It has excellent thermal and chemical stability, and it demonstrates excellent miscibility with a wide range of refrigerants, including R22 and HCFC blends.  SynCold® AB can cater to a wide temperature range within a single system due to its ability to be customized according to specific development needs. This flexibility ensures effective lubrication across high and low extremes.
 
SynCold® AB series refrigeration lubricants exhibit extremely low foaming tendency and can be completely miscible with mineral refrigeration oils in any proportion.

​

SynCold® AB series demonstrate exceptional refrigeration lubricant solubility, with a two-phase separation temperature (20% oil, 80% R22) of less than -60°C.

​

SynCold® AB 68 is specifically designed for ammonia (R717) applications, delivering outstanding high and low-temperature performance even under high-temperature conditions or evaporation temperatures below -33°C. 

​

SynCold® AB 68 is also suitable for systems using hydrocarbons (such as R600a) as refrigerants and in conjunction with refrigerant R402A/B. Compared to traditional mineral oils, this product offers superior high and low-temperature performance and safety, as evidenced by its improved viscosity index, flash point, fire point, and pour point.
