From April 8 to 10, 2026, the 37th China International Exhibition for Refrigeration, Air Conditioning, Heating, Ventilation and Food Freezing Processing (China Refrigeration Expo) kicked off grandly at Beijing Capital International Exhibition & Convention Center. Guangzhou Qishanr Technologies, with its QISHANR brand, made a stunning appearance at Booth A1A84, launching the new QSL-PAG46/68/100/150 series of automotive air conditioning refrigeration oils, injecting new momentum into the refrigeration industry with high-performance synthetic lubrication technology.
The newly launched PAG series refrigeration oils, refined with polyalkylene glycol as the core raw material and compounded with exclusive additives, feature excellent dilution resistance, thermal stability and shear stability. They are perfectly compatible with various refrigerants such as HFCs, HFOs and CO₂, and deliver outstanding performance especially in flooded screw compressors. The four models cover different viscosity requirements: QSL-PAG46 (44.5 cst) is suitable for light-load working conditions; QSL-PAG68/100 balances lubrication and fluidity to meet the needs of mainstream commercial and industrial refrigeration; QSL-PAG150, a high-viscosity model, can withstand heavy-load and high-temperature extreme working conditions. The series fully covers automotive, commercial and industrial refrigeration and air conditioning compressor scenarios, and is applicable to all types of compressors including reciprocating, screw and scroll compressors.
Guangzhou Qishanr Technologies has been deeply engaged in the R&D of medium and high-end compressor oils. Focusing on the pain points of the automotive air conditioning field, the new products achieve low ash content and high viscosity index through molecular-level optimization, which not only improves the operational stability of compressors, but also effectively reduces energy consumption, boosting the efficient operation of new energy vehicle air conditioning systems. At the exhibition, the QISHANR team also provided customized selection solutions and OEM/ODM processing services, attracting high attention from industry customers.
Standing at the wave of green upgrading of the global refrigeration industry, QISHANR will take this new product launch as a new starting point, continue to deepen lubrication technology innovation, empower the full-scenario upgrading of automotive, commercial and industrial refrigeration with more environmentally friendly, efficient and adaptive products, inject lasting impetus into the low-carbon transformation and high-quality development of the global refrigeration industry, and build a global benchmark for China's national refrigeration lubrication brand.
