Industrial freezing has transitioned far beyond basic cold storage units. Today, the global manufacturing sector demands precision-engineered cryogenic machinery capable of operating at temperatures down to -180°C. Modern industrial freezers are vital components in energy conservation, medical hazardous waste management, natural gas purification, and advanced petrochemical workflows. Driven by stringent environmental legislation and the rise of clean energy matrices, the industrial refrigeration sector is witnessing a massive migration toward modular, skid-mounted architectures, integrated intelligence, and low-GWP (Global Warming Potential) refrigeration technologies.
As global heavy industries align with carbon neutrality targets, the demand for highly optimized thermodynamic solutions has escalated. Modern systems require the integration of complex gas liquefaction tech, deacidification, dehydration, and heavy hydrocarbon recovery. These technologies form a protective mechanism for gas networks, minimizing emissions while maximizing cryogenic recovery efficiency. For procurement officers worldwide, finding a manufacturer that integrates design, pressure vessel fabrication, and advanced thermodynamics is critical.
At the heart of Hebei Hongke Qingneng Environmental Protection Equipment Co., Ltd. lies a profound scientific heritage. Unlike conventional manufacturers that assemble generic components, our processes are developed and supervised by an elite academic team from Tsinghua University and the Institute of Physics and Chemistry Technology of the Chinese Academy of Sciences.

General Manager
Ph.D. candidate and Senior Engineer at CAS. He has directed national science and technology initiatives under the "12th Five-Year Plan." Author of 24 international peer-reviewed papers (11 indexed in SCI/EI) and inventor of multiple national patents, his research is instrumental in translating cryogenics into market-ready industrial freezers.
Chief Engineer
Doctor of Engineering from CAS. His breakthrough research on "Technology Development and Application of Skid-mounted Natural Gas Liquefaction Units" earned him top-tier science prizes. He specializes in mixed working medium phase change heat transfer, aligning basic research with heavy industrial production.
"By utilizing advanced cryogenic phase-change thermodynamics and mixed working medium cycles (MRC), we design industrial refrigeration systems that achieve up to 30% greater energy efficiency compared to traditional single-component cycles."
Our factory houses specialized engineering groups focused on non-standard industrial freezing and environmental technology. Our industrial capabilities are divided into four primary departments:
We manufacture deep-temperature freezers operating between -40℃ and -180℃. These systems are used in bio-pharmaceutical storage, cold-trap VOC recovery, and deep-freeze drying equipment (-70℃ to -100℃). By applying our custom vacuum cold trap designs, we successfully condense volatile industrial compounds, making our machines essential for clean chemical processing.
Specializing in skid-mounted natural gas, coalbed methane (CBM), and shale gas liquefaction plants. Using our multi-component mixed refrigerant cycle, we reduce infrastructure requirements, allowing remote wells to capture and liquefy gas directly. This modular setup offers rapid deployment and flexibility for fluctuating gas flow rates.
Managing hazardous biological wastes requires reliable thermal processes. We build centralized and mobile medical waste disposal units that integrate shredding, sterilization, and cooling. These machines meet global biosafety requirements, converting hazardous medical waste into safe, non-toxic residue.
Equipped with an A2 level manufacturing license, we design and build custom heat exchangers, pressure vessels, and specialized experimental benches. Our pressure vessels are manufactured to withstand high pressures and low temperatures, ensuring compliance with global regulatory standards.
Manufacturing industrial-grade freezers and cryogenic pressure vessels requires modern facilities and strict quality control. Located in the Sanhe Economic Development Zone, Langfang City, our production plant operates under Factory 4.0 principles, integrating automated welding, digital twin testing, and online pressure testing.
This vertically integrated manufacturing model allows us to supply non-standard pressure vessels and skid-mounted refrigeration systems at competitive pricing without compromising quality.
Industrial freezers and gas liquefaction skids operate in demanding environments—from remote gas fields in Central Asia to high-standard research institutes in North America and biomedical plants in Europe. We custom-engineer each system to comply with international specifications and match local operating conditions.
Our deacidification, dehydration, and heavy hydrocarbon removal skids prepare natural gas for liquefaction. These purification processes are essential for preventing freeze-ups in cryogenic exchangers. Additionally, our tail gas recovery units capture and liquefy BOG (Boil-Off Gas) and extract high-value helium, transforming waste streams into revenue.
For public health authorities and universities, our mobile and centralized high-temperature steam sterilization systems provide safe waste treatment. By combining thermal sterilization with integrated industrial shredders, these units eliminate pathogens at the source, reducing the logistics costs of transporting biohazardous waste.
