Description of L-DRA ammonia compressor oil

Compressor oil L-DRA for refrigeration units is formulated for industrial refrigeration compressors and systems using ammonia refrigerant R717. Its controlled low-temperature properties help the oil maintain fluidity through evaporators and other low-temperature system components, supporting operation across varying temperature zones.

The oil also provides oxidation resistance, cleanliness, and deposit control, helping to reduce carbon buildup on valves and other high-temperature components. Ningbo MOS Chemical Co., Ltd. supplies L-DRA refrigeration oil to refrigeration equipment manufacturers, lubricant importers, distributors, wholesalers, and industrial end-users through wholesale purchases, OEM, private labels, and export cooperation. Production support is provided through the manufacturing network invested by MOSINTER GROUP.
