High-performance vacuum insulated hardware, skid-mounted energy systems, and high-purity processing equipment engineered for global standard compliance.
Industrial Whitepaper: Exploring Deep Cryogenics, Multi-Layer Vacuum Insulation (MLI), and Thermal Engineering Excellence from Chinese Manufacturing.
Modern clean energy transformation, aerospace applications, and extreme industrial refrigeration projects operate in temperature zones down to -180℃ to -269℃. Under these deep-cryogenic constraints, thermal conductivity represents the largest operational threat. Conventional insulation systems fail to prevent heat leakage, causing rapid boil-off of liquids (such as LNG, helium, and nitrogen) and substantial energy loss. As a leading technical force in China's industrial base, Hebei Hongke Qingneng Environmental Protection Equipment Co., Ltd. addresses these engineering boundaries with advanced vacuum insulation science.
Industrial insulation vacuum setups employ Double-Walled High-Vacuum Insulation combined with Multi-Layer Insulation (MLI) systems (or radiation shields). MLI consists of alternating layers of highly reflective aluminum foil and low-conductivity spacer materials (such as fiberglass paper or polyester web) working under a high-vacuum environment ($1 \times 10^{-2} \text{ Pa}$ or lower). By eliminating gas conduction and convection while minimizing radiative heat transfer, our setups guarantee minimal Boil-Off Rates (BOR) in pressure vessels, skid-mounted LNG units, and cold traps.

Our core R&D team features industry specialists from Tsinghua University and the Institute of Physics and Chemistry Technology (CAS). Our research into phase change heat transfer characteristics and flow properties under extreme mixed working mediums drives our industrial designs.
We hold A2-level Pressure Vessel Manufacturing Licences, Pressure Pipeline Component Manufacturing Licenses, GB/T19001-2016 quality certifications, and Sinopec HSSE / CNPC Health, Safety, and Environment management approvals.
Our systems facilitate carbon reduction and VOC emissions mitigation. Through targeted gas recovery and resource preservation machinery, we help operators achieve net-zero targets and comply with national environmental protection laws.
Custom engineering tailored to real-world industrial and commercial operations around the globe.
Skid-mounted systems require insulation vacuum integrity to maintain natural gas at liquefaction temperatures (-162°C). Our double-walled pipelines and cold boxes prevent Boil-Off Gas (BOG), optimizing yield at remote gas fields and shale extraction wells.
Volatile Organic Compounds (VOCs) require condensation under ultra-low temperatures. Our vacuum cold traps operating at -135℃ efficiently capture hazardous organic gases, allowing facilities to recover products and meet emissions standards.
Our centralized and mobile high-temperature steam sterilization systems rely on thermal isolation. Advanced insulation structures isolate heat, maintaining uniform internal processing chambers and protecting external electronics.

Leveraging localized clusters, advanced manufacturing, and strategic transport corridors to maximize production efficiency.
Located in the Sanhe Economic Development Zone, Langfang, Hebei, our factory operates within a mature industrial and raw material supply ecosystem. This geographic proximity to domestic steel production, heavy casting industries, and specialized logistics networks reduces transportation overhead and lead times.
Our raw material procurement features quality controls on pressure vessel plate steel (such as 304/304L stainless steel, carbon steels, and specialty cryogenic alloys). The factory features automatic double-sided submerged arc welding machinery, heavy-duty plate rolling machines, high-resolution X-ray inspection bays, and automated helium leak detection chambers. This system maintains short lead times even when managing large, complex engineering requests.
Future-proofing our engineering to meet the next wave of industrial requirements.
With boiling points at -253°C, liquid hydrogen transportation demands high-integrity insulation. Our engineering team is developing next-generation composite Multi-layer Insulation (MLI) systems using aerogels and thin radiation shields to further reduce static evaporation rates.
Vacuum loss can lead to equipment downtime. We are integrating micro-vacuum pressure sensors directly inside double-walled chambers to enable remote monitoring and predictive maintenance alerts.
We optimize manufacturing emissions by utilizing solar arrays and heat recovery systems within our Langfang production bays, aligning our hardware with global ESG initiatives.
Meeting requirements across international markets with code-compliant design and testing.
Shipping complex chemical plant skids and high-vacuum equipment worldwide requires strict code compliance. All of our designs undergo structural verification, FEA stress analyses, and fatigue inspections tailored to destination requirements:
