Viscosity grade. This oil measures 124.6 cSt at 40 °C. That figure falls between the ISO VG 100 band (90–110 cSt) and the ISO VG 150 band (135–165 cSt) defined by DIN ISO 3448, so no ISO VG class number corresponds to it — a value that falls between two steps has no class of its own. Compare grades on the measured 40 °C viscosity rather than on the class label.
This oil is manufactured and supplied by Guangzhou Qishanr Technologies Co., Ltd., trading as the brand QISHANR. The company is based in Foshan, Guangdong, adjacent to Guangzhou Port, and has been producing lubricants for more than 10 years from its own blending plant. That plant runs at an annual capacity of 6,000 tonnes, which is what allows us to hold stock on the grades we list and quote firm lead times rather than promising on behalf of a third party.
Refrigeration oils are the core of the business, but they are not the whole plant. The same lines produce general industrial lubricants, so a mixed enquiry that covers both refrigeration oils and ordinary industrial grades can be quoted, packed and shipped together instead of being split across suppliers.
This is not the full range. Specialised ester base oils and lubricant additives are produced in-house as well, which is the reason the synthetic ester grades can be specified to a target rather than bought off a shelf. If the grade you need is not listed above, send the specification or the product you are replacing and we will confirm whether we produce it.
Long-term partners get pricing that reflects a stable manufacturing base rather than a trading margin, and the same technical contact stays with the account from grade selection through to repeat orders.
