From March 16 to 18, 2026, the 16th CHINA HEAT PUMP EXHIBITION 2026 grandly opened at Shijiazhuang International Convention and Exhibition Center, with the eye-catching theme slogan The World Looks to China for Heat Pumps.
Guangzhou Qishanr Technologies Co., Ltd. made a significant appearance with QISHANR brand heat pump refrigeration oil series, highlighting three core models—QSL-170H, QSL-220H, and QSL-320H—to deliver high-performance lubrication solutions for northern heating and industrial heat pump scenarios.
The three showcased POE (polyol ester) refrigeration oils are eco-friendly synthetic products developed with proprietary technology, offering excellent lubricity, wear resistance, chemical stability, and full compatibility with mainstream refrigerants such as HFCs, HCFCs, and HFOs. Corresponding to kinematic viscosity grades of 170, 220, and 320 respectively, these oils can directly replace equivalent viscosity products from leading international brands including Bitzer, Hanbell, and Suniso, completely resolving compatibility issues between different brands and helping users reduce maintenance costs by over 56%. They are particularly well-suited for screw compressors operating in low-temperature heating conditions in northern China.
In addition, the exhibition also featured mid-to-low viscosity models from the QSL series (QSL-32H, QSL-46H, QSL-68H, QSL-100H, QSL-120H, QSL-150H), covering a full range of household, commercial, and industrial refrigeration scenarios. Customized selection support and OEM/ODM processing services are available to clients.
Guangzhou Qishanr Technologies will continue to deepen its expertise in high-performance refrigeration oil technology. In the future, it will further expand product adaptability to complex operating conditions such as extreme low and high temperatures, delivering more environmentally friendly and efficient lubrication solutions to support the low-carbon transformation and sustainable development of the global heat pump and refrigeration industry.
