Product Description

This product is formulated using premium base oils, combined with a variety of high-quality additives—such as antioxidants, anti-wear agents, emulsion inhibitors, antifoaming agents, and rust preventatives—through advanced manufacturing processes.

Product Performance

Good low-temperature fluidity ensures it won’t condense in cold areas like evaporators;

Good oxidative stability effectively extends the service life of the oil;

Good chemical stability prevents reactions with refrigerants.

Implementation Standards

GB/T 16630-2012

Scope of Application

Suitable for open-type refrigerators using ammonia (R717) as the refrigerant.

Instructions for Use and Precautions

Select the appropriate oil viscosity according to the equipment's lubrication guidelines. During use and storage, prevent contamination by foreign objects, and strictly avoid mixing in mechanical impurities or water. Ensure the oil tank remains clean—when changing the oil, thoroughly flush both the tank and oil lines. Never mix this oil with other types, and never combine different oil formulations.
