Explore our core engineering configurations designed for peak operational efficiency and extreme thermal requirements.
Hebei Hongke Qingneng Environmental Protection Equipment Co., Ltd. was established in June 2021 with a registered capital of 78 million yuan. Located in the industrial heartland of the Sanhe Economic Development Zone, Langfang City, we have positioned ourselves as an R&D and manufacturing powerhouse dedicated to energy conservation, advanced industrial refrigeration, and environmental protection hardware.
Our core industrial expertise spans the engineering, thermal calculation, and production of non-standard pressure vessels, centralized and mobile medical waste high-temperature steam systems, biopharmaceutical toxic wastewater treatment systems, and skid-mounted hydrocarbon/natural gas liquefaction processes. By bridging the gap between scientific theory and shop-floor execution, we provide customized equipment built for the most punishing operational environments.
We hold the national A2-level pressure vessel manufacturing license, pressure pipeline component manufacturing license, ISO9001 quality system certification, and specialized petroleum health, safety, and environmental system certifications (Sinopec HSSE / CNPC HSE).
Our solutions are engineered by doctoral teams from Tsinghua University and the Institute of Physics and Chemistry Technology of the Chinese Academy of Sciences (CAS).

Bridging cryogenic physics with heavy industrial manufacturing to solve complex thermal and gas recovery challenges.
Operating complex thermal refrigeration and high-pressure purification systems requires adherence to strict global safety codes and environmental standards. We understand the regulatory landscapes governing pressure equipment in North America (ASME), Europe (PED/CE), and Asia-Pacific (GB/T). Our engineers integrate compliance verification directly into the early stages of thermodynamic simulation.
For gas processing plants and biological safety equipment (such as medical waste processors and laboratory animal hydrolysis units), containment integrity is paramount. We provide full lifecycle services that ensure your system remains verified, calibrated, and operational through rigorous Factory Acceptance Testing (FAT), Site Acceptance Testing (SAT), and ongoing preventative maintenance.
Our skid-mounted process designs focus on mitigating fugitive emissions. Utilizing high-efficiency hermetic sealing and advanced VOC recovery loops, our systems prevent product loss while exceeding global emissions regulations.
A showcase of our custom systems built, deployed, and validated across high-pressure environments.
Designed to handle biological waste at high temperatures, ensuring complete bio-safety compliance for laboratory facilities.
Fully mobile, containerized steam sterilization units optimized for rapid deployment and emergency response scenarios.
Skid-mounted natural gas purification and liquefaction units designed for remote operations and stranded gas recovery.
High-capacity plant systems utilizing saturated steam under pressure to process hazardous waste safely and efficiently.
Our commitment to R&D focuses on lowering operational expenditure through thermal efficiency improvements.
Reaching temperatures below -150°C efficiently requires a thorough understanding of phase changes in mixed working media. Our technical teams, drawing on experience from the Chinese Academy of Sciences, design proprietary refrigerant formulations tailored to specific load requirements. By minimizing thermodynamic irreversibilities in suction lines and evaporators, our systems reduce electrical consumption by up to 22% compared to standard configurations.
This thermal precision directly benefits sectors like LNG processing, where recovery rates are closely linked to temperature control. Additionally, our non-standard pressure vessels are designed using advanced finite element analysis (FEA). This process minimizes material stress points, extending the operational life of equipment under cyclical thermal loads.
In the field of medical waste and hazardous pathogen neutralization, our high-temperature autoclaves feature specialized steam distribution profiles. These systems ensure uniform thermal penetration, eliminating cold spots during treatment cycles.

Unlike single-refrigerant systems, mixed working medium systems utilize a customized blend of fluids. This blend exhibits a temperature glide during phase change, matching the cooling curve of the process fluid. By minimizing thermal heat exchange losses, these systems achieve temperatures from -40°C down to -180°C with lower compressor power requirements.
Skid-mounted systems are pre-assembled, piped, wired, and tested at our Langfang factory before shipping. This approach reduces civil works and installation time on-site, which is particularly beneficial for remote areas like coalbed methane extraction fields or shale gas wells.
We hold an A2-level pressure vessel manufacturing license, allowing us to fabricate high-pressure and medium-pressure industrial vessels. We design and construct equipment in compliance with GB150 guidelines, and can adapt designs to meet ASME Section VIII or European CE/PED requirements for international installations.
Our centralized and mobile medical waste systems use saturated steam under high pressures (typically 134°C or higher). By combining mechanical shredding with uniform steam distribution, we achieve high log-reduction rates for pathogens, rendering bio-hazardous waste safe for disposal.
