Engineered with high thermodynamic efficiency and A2 pressure vessel standards for modern industrial applications.
Hebei Hongke Qingneng Environmental Protection Equipment Co., Ltd. was established in June 2021 with a substantial registered capital of 78 million yuan. Headquartered within the industrial base of Sanhe Economic Development Zone, Langfang City, our enterprise represents a premier industrial center specializing in the research, design, development, and manufacturing of state-of-the-art energy conservation, environmental protection, and heavy-duty refrigeration systems.
We bridge the gap between academic innovation and heavy-duty industrial application. Backed by key researchers from elite institutions, including Tsinghua University and the Institute of Physics and Chemistry Technology of the Chinese Academy of Sciences (CAS), our technical framework utilizes high-purity cryogenic processes, advanced gas-phase thermodynamics, and top-tier pressure control. We deliver high-value turnkey equipment systems, specialized industrial freezers, and skid-mounted natural gas liquefaction plants worldwide.
Optimizing thermodynamic parameters for pharmaceutical preservation, aerospace testing, and gas separation processing.
Designed for large-scale logistics, precision metallurgic hardening, and pharmaceutical storage. Engineered using eco-friendly mixed-refrigerant auto-cascade cycles, these industrial-grade freezers provide precise temperature uniformity and high structural reliability under constant continuous load.
Crucial for preservation without cellular damage. Our industrial freeze dryers remove water content from heat-sensitive substances under high vacuum levels, maintaining structural integrity for vaccines, laboratory animal biological matrices, and targeted enzyme solutions.
Prevents volatile vapors from entering vacuum pumps. Our ultracold traps minimize vacuum pump corrosion and fluid contamination, which significantly reduces downtime in large chemical extraction plants and heavy-duty gas recovery setups.
To serve heavy industries, our industrial freezers utilize high-density polyurethane insulation, multi-layer vacuum seals, and smart cooling controls to minimize operational power consumption.

Analyzing procurement criteria for international engineering procurement and construction (EPC) companies.
Global procurement teams prioritize manufacturing partners with certified engineering credentials. Our factory maintains the prestigious A2 Level Pressure Vessel Manufacturing License, which meets design demands for high-pressure storage, vaporizers, and industrial cryostats.
Under international environmental regulations, old refrigerants are phased out. We offer eco-friendly mixed hydrocarbon refrigerants that reduce global warming impact while keeping cooling efficiency high.
With high on-site installation costs, global buyers require ready-to-use skid-mounted systems. Our factory builds fully integrated, pre-wired, and pre-tested skid assemblies to simplify installation.
Our core engineering team comprises nationally recognized cryogenic scientists and researchers from the Chinese Academy of Sciences.
