Engineered to deliver exceptional thermal stability and continuous operation under extreme environments.
Founded in June 2021 with a registered capital of 78 million yuan, Hebei Hongke Qingneng Environmental Protection Equipment Co., Ltd. stands as a premier modern technology hub in Sanhe Economic Development Zone, Langfang City. We specialize in the research, design, engineering, and manufacturing of ultra-low temperature, heavy-duty cooling technologies and high-pressure cryogenic systems.
Through close technical collaborations with Tsinghua University and the Institute of Physics and Chemistry Technology, Chinese Academy of Sciences (CAS), our engineers have developed advanced processes in the industrial refrigeration sector, bridging the gap between typical industrial refrigeration needs and extreme ultra-low temperature requirements. Our systems operate efficiently within the range of -40℃ to -180℃, catering to complex petrochemical processing, environmental tail gas recycling, and highly sensitive biomedical storage applications.
Pushing the thermodynamic limits with advanced thermal dynamics, mixed refrigerant cycles, and automated recovery loops.
Through our dedicated cryogenic research, we deliver highly reliable refrigeration systems that support critical pharmaceutical extraction processes, industrial chemical cooling, gas recovery, and special aerospace test configurations. Our units are optimized to work under intense environmental stresses without performance drops.
Our heavy-duty cryogenic freezers utilize mixed hydrocarbon and nitrogen refrigeration cycles to optimize thermal efficiency. By using multi-component mixed working mediums, we lower the total power input requirement for deep freezing compared to traditional cascade systems, significantly reducing operating costs.
We are a market leader in China for BOG (Boil-Off Gas) tail gas helium extraction technologies. Our cryogenic separation methods permit precise fractionation of helium from liquefied natural gas streams, delivering highly sought-after industrial raw materials while enhancing energy productivity.
Holding the national A2 level pressure vessel manufacturing license, our facilities design, simulate, and manufacture custom containment structures, shell-and-tube heat exchangers, vacuum chambers, and high-pressure cryogenic pipework matching rigorous international criteria.
Our management and technology teams originate from top-tier research institutes, guiding our engineering developments with academic rigor.

His deep research has earned him the Beijing Science and Technology First Prize, enabling the deployment of highly stable and energy-efficient systems globally.
Enabling massive gas recovery, environmental compliance, and high-efficiency medical waste neutralization.
We build centralized and mobile medical waste disinfection systems utilizing high-temperature steam sterilization technology. These units are highly automated, ensuring biological safety while lowering energy consumption compared to traditional incineration techniques.
Offering highly adaptable modular, skid-mounted LNG systems designed for low-yield gas fields, shale gas, or associated gas extraction. These systems can be moved from site to site easily, offering quick startup and shutdown capabilities to prevent flaring.
Our heavy-duty refrigeration expertise is directly applied to volatile organic compound (VOC) condensation systems. By cooling industrial exhaust streams down to ultra-low temperatures, we condense and recover solvents, matching national carbon emission and pollution goals.
Our modern manufacturing facility in the Sanhe Economic Development Zone is built around advanced production lines, automated CNC welding processes, and non-destructive testing (NDT) rooms. With a robust logistics network in North China and localized material supply, we promise outstanding pricing and high reliability.
Our factory processes conform to international standards like ISO 9001. We focus heavily on reducing waste and energy use during production. We perform extensive quality testing, such as hydrostatic and pneumatic tests, helium mass spectrometer leak detection, and thermal stress tests, before shipping any system.
Proof of our performance and execution in heavy industrial, medical, and petrochemical fields.
Ensuring our international projects meet standard regulatory requirements, quality expectations, and HSE parameters.
We are officially certified for A2 level pressure vessel manufacturing and pressure piping component production in China, aligning our products with international safety standards.
