Shanghai First Refrigerating Machinery Works Co., Ltd., founded in 1934, is one of the pioneers of China's refrigeration industry. The company is a comprehensive solution provider integrating R&D, engineering design, manufacturing, system integration, installation, and after-sales services for refrigeration, heating, and energy systems.

As a historic leader in the industry, the company has developed and manufactured several "firsts" in China, including the first reciprocating refrigeration compressor, the first centrifugal compressor, the first lithium bromide absorption chiller, and the first screw refrigeration compressor, laying a solid foundation for China's refrigeration and low-temperature engineering sector.

Its product portfolio covers a full range of screw compressor units, single- and double-stage screw chillers, water chillers, brine and glycol units, ammonia pump units, air coolers, evaporators, condensers, and industrial & commercial heat exchangers. Building on this foundation, the company has expanded into heat pump systems, steam compression units, screw expanders, ORC waste heat recovery systems, CCUS equipment, and hydrogen/biogas purification systems, serving industrial energy recovery and green energy utilization markets.

The company specializes in the design and manufacturing of heat exchangers and pressure vessels, holding Chinese Class D pressure vessel licenses and pressure piping component manufacturing licenses, as well as international certifications including ASME, CE/PED, DNV-GL, NK, ABS, BV, and CCS. In recent years, it has obtained 27 patents for inventions and utility models. Its products are widely used in cold storage and refrigeration, food & beverage processing, petrochemicals, biopharmaceuticals, new energy, environmental protection, electronics, marine engineering, and central HVAC systems.

Operating under a group structure, the company manages four major business divisions-Commercial Refrigeration, Industrial Refrigeration, Retail & Supermarket Cold Chain, and Eco-friendly Air Conditioning-and owns several specialized subsidiaries, including Shanghai General Fushi Refrigeration Equipment Co., Ltd., Shanghai Spetech Pressure Vessel Co., Ltd., and Shanghai First Union Refrigeration and Heating Equipment Co., Ltd. This structure enables an integrated industrial chain from core equipment manufacturing to complete system solutions.

Driven by China's carbon neutrality goals, Shanghai First Refrigerating Machinery Works Co., Ltd. is committed to advancing industrial energy efficiency, waste heat and cold recovery, mine heat hazard control, LNG cold energy utilization, district energy systems, and integrated green energy solutions, delivering safe, efficient, low-carbon, and sustainable energy solutions to customers worldwide.
