Dedicated to perfection, relentlessly pursuing excellence, pioneering core innovation, and powering the future.

Bingshan Matsushita Compressor (Dalian) Co., Ltd. was originally established in September 1994 as Dalian Sanyo Compressor Co., Ltd., and later evolved from Matsushita Compressor (Dalian) Co., Ltd. In December 2022, the company was renamed Bingshan Matsushita Compressor (Dalian) Co., Ltd. and is now a core member enterprise of the Bingshan Group. The company has total investment of RMB 680 million, registered capital of RMB 442 million, occupies a site of 87,000 square meters, with a building area of 89,000 square meters, and employs more than 1,400 people. The company is located in Dalian, an important economic hub on China’s eastern coast.

The company leverages a state-of-the-art intelligent manufacturing and quality-control system to specialize in the production of both inverter and fixed-speed scroll compressors. Its product portfolio comprises eight major series—B, C, D, E, F, G, K, and W—designed to meet the requirements of mainstream global markets, support multiple electrical standards, and be compatible with environmentally friendly refrigerants, with power ratings ranging from 3 to 30 horsepower. In recent years, the company has established itself as a comprehensive compressor manufacturer capable of delivering end-to-end solutions across a wide range of applications, including commercial air conditioning, electric bus air conditioning, rail transit air conditioning, data center air conditioning, energy-storage thermal management, heat-pump heating, heat-pump water heating, heat-pump drying, industrial heat pumps, and refrigeration and cold storage.
