| Product Overview
SynCold® RLD series products are formulated with carefully selected polyol esters and specialized additives, offering excellent miscibility, thermal stability, lubricity, and hydrolytic resistance. These products are precisely synthesized using a proprietary process and are not simply blends of esters with varying viscosities. They are suitable for household refrigerators, residential air-conditioning units, industrial refrigeration systems, and all applications that recommend HFC refrigerants.It exhibits the required miscibility with SynCold® RLD series products at critical temperatures, as well as acceptable viscosity for refrigerant–lubricant blends, while offering excellent wear resistance, thermal stability, and an extended service life. It is compatible with HCFC and CFC refrigerants, as well as other refrigeration lubricants such as mineral oils, polyalphaolefins, and alkylbenzenes.
| Applications and Compressor Types
