Product overview
开山冷冻 develops energy-saving, environmentally conscious industrial refrigeration systems and offers turnkey refrigeration solutions. Manufacturing base located in the heavy equipment industrial zone of Lingang New City, Pudong, Shanghai. The company integrates compressor R&D and manufacturing, refrigeration system engineering and installation, and design and manufacture of refrigeration units and heat exchangers to deliver customized system solutions.

Industrial refrigeration
Equipment for industrial process cooling. 开山冷冻 supplies refrigeration systems sized and configured according to customer process requirements (cooling capacity, process medium, system layout), special configurations (anti-corrosion protection, explosive-atmosphere certification, electrical/instrumentation) or applicable standards. A series of standard units developed for industrial applications includes screw-compressor units, compression-condensing units, brine units and pressure vessels. 开山螺杆压缩机组 are compatible with ammonia, various HFC refrigerants and hydrocarbons such as propane and propylene; they offer improved electrical efficiency, typically around 10% savings compared with similar products.
