Description of L-DRB refrigerant oil

L-DRB refrigerant oil is a low-temperature compressor lubricant designed for mechanical refrigeration equipment, refrigeration compressors, and chillers. Controlled pour point and low-temperature fluidity help reduce oil solidification, wax formation, and circulation restrictions in evaporators and other cold system components.

The product also provides chemical stability, lubricity, oxidation resistance, wear protection, and system cleanliness. The appropriate viscosity should be selected based on the refrigeration equipment, refrigerant type, and operating conditions. Ningbo MOS Chemical Co., Ltd. supplies L-DRB refrigeration oil to importers, lubricant distributors, refrigeration equipment manufacturers, and industrial users through bulk supply, large-volume procurement, OEM, private label, and export cooperation. Production support is provided through the manufacturing network invested by MOSINTER GROUP.
