  • -70 ℃ to -100 ℃ high-capacity freeze dryers
  • Vacuum cold traps (-135 ℃) for recovery systems

Technical Roadmap: Deep Cryogenics & Recovery

Our engineering division designs cryogenic frameworks that address efficiency challenges in gas processing and industrial refrigeration.

Mixed Refrigerants (MR) Cycle Integration
Our proprietary mixed refrigerant systems utilize advanced thermodynamic modeling to match heat transfer curves in multi-stream heat exchangers, minimizing energy loss during gas liquefaction.
Non-Standard Shell & Tube Optimization
Custom engineering of mechanical components under our A2 license, enabling heat exchange systems to handle extreme temperature deltas and corrosive media safely.
Helium Extraction & BOG Recovery
Specialized separation systems engineered to recover helium and Boil-off Gas (BOG) from LNG storage, converting low-pressure venting issues into profitable streams.

China Supply Chain Resilience & Manufacturing Superiority

Situated within the Sanhe Economic Development Zone, Langfang City, Hebei Province, our factory enjoys a geographical position that connects raw material procurement with global logistics lines. Our supply chain leverages local metallurgical clusters to source high-grade stainless steels (such as 304L, 316L, and specialized nickel alloys) essential for extreme deep-freezing applications.

Through systematic supplier qualification and rigorous manufacturing protocols, we mitigate common industrial production bottlenecks. The integration of structural plate cutting, automatic orbital welding, X-ray non-destructive testing, and pressure testing within a single facility allows us to reduce turnaround times by 20% compared to typical Western European or North American manufacturing yards.

Additionally, our closeness to Tianjin and Shanghai shipping ports enables the transport of modular, skid-mounted structures directly to international destinations, ensuring projects stay on track and within budget.

Worldwide Installations and Case Presentations

Our solutions have been implemented in oilfields, biomedical facilities, and remote locations around the world. These case presentations show our technology performing under demanding field conditions.

Frequently Asked Questions

Expert answers addressing the design, certification, and implementation of our industrial cryogenic and environmental treatment systems.

What is the temperature range of your industrial refrigeration machinery?
Our systems operate across deep cryogenic levels ranging from -40 ℃ down to -180 ℃. These setups are designed for liquefaction plants, helium extraction (BOG) operations, vacuum cold traps (operating at -135 ℃), and custom freeze dryers (designed for -70 ℃ to -100 ℃ range).
Does your company support international design codes like ASME or CE?
Yes, our plant holds A2 level pressure vessel manufacturing licenses, GB/T19001-2016 quality certifications, and Sinopec/CNPC health and safety management credentials. During the custom engineering phase, our technical team works with clients to align designs with international compliance rules, including ASME and EN standards.
What are the advantages of skid-mounted liquefaction equipment?
Skid-mounted configuration integrates structural piping, electrical control systems, and cooling units onto a single structural frame. This layout is fully pre-commissioned at our Langfang factory, reducing onsite installation schedules, minimizing structural foundations, and allowing easy redeployment as gas field profiles shift.
How does your VOC treatment system recover organic waste gases?
Our systems utilize advanced condensation technology alongside specialized adsorption frameworks. By lowering temperatures to liquefy chemical vapours, we recover organic compounds directly from the process flow. This approach helps chemical plants meet local environmental requirements while reclaiming raw materials.
What options do you offer for medical and animal waste treatment?
We manufacture centralized high-temperature steam sterilization systems, portable mobile waste disposal skids, and animal tissue processing chambers. These systems are designed to eliminate pathogenetic threats in compliance with international biosafety regulations.
