Engineered for extreme performance, carbon reduction, and compliant waste treatment across scientific, energy, and medical sectors.
The global demand for high-reliability freezer equipment and gas processing solutions has shifted dramatically from basic refrigeration to high-efficiency, environmentally friendly cryogenic engineering. Modern biochemical laboratories, pharmaceutical factories, and gas processing terminals require precise thermal management between -40°C and -180°C. In parallel, environmental regulations have imposed strict mandates on the containment of medical waste and volatile emissions (VOCs).
To successfully design systems capable of operating under these extreme thermodynamic boundaries, manufacturers must possess advanced capabilities in material sciences, thermodynamics, and certified high-pressure piping. This global shift highlights the need for end-to-end skid-mounted packages that minimize on-site installation, reduce thermal footprint, and ensure continuous operation under adverse conditions.
Established in June 2021 with a registered capital of 78 million yuan, Hebei Hongke Qingneng Environmental Protection Equipment Co., Ltd. sits in the industrial base of Sanhe Economic Development Zone, Langfang City.

The company maintains the A2 level pressure vessel manufacturing license, pressure pipeline component manufacturing license, GB/T19001-2016 quality system certification, and Sinopec HSSE/China Petroleum Health, Safety and Environment Management System certifications, ensuring global standard compliance.
Our complete sets of environmental protection and energy recovery systems are optimized for resource preservation, making major contributions to national carbon emission reduction, air pollution prevention, and eco-friendly pet and waste management.
Discover how our research-backed systems solve real-world cryogenic, environmental, and thermal challenges.
Our cryogenic processes are built around mixed refrigerant cycles (MRC) and auto-cascade refrigeration technologies. By developing optimized mixtures of working fluids, we achieve high thermodynamic efficiency at ultra-low temperature ranges.
Situated in the industrial heart of Hebei within the Sanhe Economic Development Zone, our factory leverages a highly mature local manufacturing ecosystem. This proximity allows us to deliver substantial capital and operational savings:
Different regions present unique mechanical and chemical challenges. Our solutions are custom-configured for localized demands:
In regions with undeveloped pipeline infrastructure, our small skid-mounted LNG liquefaction units turn stranded gas and coalbed methane into liquid fuels directly at the wellhead, preventing resource wasting and venting.
Our centralized and mobile medical waste autoclaves handle hazardous clinical waste using high-temperature steam, guaranteeing high disinfection rates without producing toxic incinerator ash.
Advanced VOC exhaust treatment systems combine low-temperature condensation with carbon bed adsorption to recover volatile solvents, allowing compliance with strict clean-air guidelines.
Explore some of our real-world system deployments engineered for safety, compliance, and thermal performance.
Designed for research institutes to safely process animal carcasses via high-temperature thermal hydrolysis.
Skid-mounted and trailer-mounted systems featuring rapid sterilization for disaster zones or remote areas.
Direct capture of oilfield associated gas to produce high-value LNG on-site, cutting carbon footprint.
Large-scale, fully automated industrial sterilization plants supporting regional healthcare centers.
Hongke Qingneng specializes in four main areas of environmental and cryogenic engineering.
Centralized medical waste high-temperature steam treatment equipment, mobile medical waste disposal units, and animal tissue (residue) processing equipment utilizing hydrothermal hydrolysis for biological pathogen sterilization.
Skid-mounted liquefaction equipment for natural gas and associated gas, gas purification equipment (deacidification, dehydration, and heavy hydrocarbon removal), and complete liquefaction plant systems.
Custom pressure vessels built under national A2 manufacturing certifications, experimental laboratory benches, shell and tube heat exchangers, and high-performance hot air stoves.
Ultra-low temperature refrigeration machines operating from -40°C down to -180°C, high-capacity freeze dryers working between -70°C and -100°C, and vacuum cold traps operating at -135°C.
How we ensure trouble-free installation, operation, and safety approval in foreign jurisdictions.
We fabricate pressure systems to align with international requirements. All mechanical parts, shell welds, and structural piping designs can be customized to match European CE or ASME boiler and pressure vessel codes, ensuring smooth approval processes with local safety regulators.
Our engineers provide remote or on-site guidance during installation, cold-loop testing, and hot commissioning. This guarantees that parameters like thermodynamic load balances, auto-cascade pressure ranges, and steam seals match design profiles.
Every skid-mounted plant is documented with a detailed bill of materials. We maintain replacement inventory for critical components—including cryogenic expansion valves, specialized high-vacuum seals, and temperature transmitters—ensuring minimal downtime.
