The Ganghe SynCold® DRAH series products are high-performance naphthenic mineral refrigeration lubricants specially developed for commercial and industrial refrigeration as well as air-conditioning compressors.
The SynCold® DRAH series is specifically engineered for applications using ammonia as the refrigerant. Due to its almost wax-free composition, it features a low pour point and excellent fluidity at extremely low temperatures. It also helps ensure that evaporator tubes remain clean, thereby improving heat transfer and reducing maintenance downtime. Additionally, it possesses good chemical stability and is suitable for cylinder and bearing lubrication.
SynCold® DRAH refrigeration lubricant is applied in the standard factory filling of industrial refrigeration equipment and OEM retrofitting operations. It possesses the low-temperature performance advantages characteristic of high-performance naphthenic products, with outstanding "sludge dissolving capacity and paint film inhibition" properties, and exhibits strong environmental adaptability for equipment systems operating in both high and low-temperature refrigeration environments.
As a naphthenic mineral oil type, its use with HFCs refrigerants is not recommended due to the constraints of miscibility with refrigerants.
The test results of the refrigeration lubricant's ammonia resistance (in accordance with DIN 51538) show that SynCold® DRAH has good chemical stability when using R717 refrigerant, and has no adverse effects on metals and other materials such as rubber.
