Guangxi Changxue Refrigeration Co., Ltd. is a professional refrigeration and cold-chain equipment manufacturer headquartered in Yulin, Guangxi. Its subsidiaries include Guangxi Hengsen Refrigeration Co., Ltd. and Yulin Pancheng Electromechanical Equipment Co., Ltd. Through its independent brand “Chang Xue”, the company offers a complete cold-chain range — from insulated panels and condensing units to intelligent control cabinets — engineered to your project, climate and capacity.
Driven by strong production and R&D capabilities, the company runs 12 specialised production workshops with around 20,000 m² of standardised factory floor, on a site of 33 acres, equipped with 4 new semi-automatic production lines and an annual output of 10 million m².
Together with its subsidiaries, the company has built the “International Cold-Chain Valley” ecosystem — covering R&D, manufacturing, supporting components and international market services — forming a new-generation, one-stop supply platform for the global cold-chain industry.
We grew up installing, then we started manufacturing
We ran refrigeration installation teams in China and lost more days to mismatched components than to actual assembly — a compressor selected for the wrong ambient, an evaporator too small for the load, a controller nobody had parameterised.
So we moved into manufacturing with a single rule: the company that builds the room owns the sizing. Today every HENGSEN package is calculated, assembled, bench-tested and shipped as one unit, with the drawings and the engineer’s phone number included.
- Load calculation done in-house, signed by an engineer
- Panels cut and cam-lock profiled on one line — numbered for assembly
- Units charged, pressure-tested and run before packing
- EU stock for the parts that fail: controllers, fans, valves, heaters
Factory audits, project reviews and exhibitions
Visiting buyers meet the engineers who size and build their room — panels numbered on the line, units charged and bench-tested before they ship. Factory audits are welcome.
Certified, tested and documented
Every HENGSEN package is built under the group’s ISO 9001 quality system, with EU CE verification and third-party product testing. Five core documents ship with your order — the complete set is available on request.
