Explore our foundational refrigeration systems, highly engineered condensation circuits, and advanced polyurethane insulation panels manufactured at our ISO-certified facility.
Within the highly demanding landscape of commercial refrigeration, temperature-sensitive cold chain storage, and precise environmental control, scroll compression machinery occupies a position of technical superiority. Invented with the mandate of offering continuous, non-pulsating gas compression, the modern scroll compressor represents the pinnacle of thermodynamic design.
A scroll compressor operates utilizing two matching, interleaving scroll members: a fixed scroll that remains static, and an orbiting scroll that oscillates within the static pocket without rotating. As the orbiting scroll pursues its path, gas enters from the suction port and becomes trapped in dynamic crescent-shaped pockets. The volume of these pockets progressively shrinks as they migrate toward the center of the scroll set, thereby raising the pressure of the vaporized refrigerant until it reaches the discharge valve.

The global shift toward cold chain modernization, eco-conscious design, and high-performance energy infrastructure.
With urbanization rapidly increasing and consumer habits shifting toward fresh, organic foods and rapid pharmaceutical delivery, the global cold chain industry is seeing unprecedented investment. In parallel, climate change policies (such as the EU F-Gas Regulation and US EPA SNAP program) are pushing manufacturers to redesign products to comply with strict global warming potential (GWP) limitations.
This macro trend has created a clear demand pattern: global contractors and procurement managers are seeking advanced, highly integrated condensing units and hermetic scroll compressors capable of running on low-GWP refrigerants (such as R448A, R449A, R290, and CO₂). Manufacturers like Shaanxi YuanShengHeTong Refrigeration Equipment Co., Ltd. bridge this market gap by manufacturing advanced PIR/PUR thermal panels alongside efficient condensing configurations.
Our scroll units are designed with optimized compliance mechanics (both axial and radial). This allows them to handle liquid slugging without breaking, meaning they last longer in unstable agricultural or harsh industrial environments where power and load fluctuations are common.
Established as an industry leader, Shaanxi YuanShengHeTong is a professional factory and enterprise focusing on insulation panels and refrigeration equipment. Besides product manufacture, we also provide comprehensive services including system design, professional installation, on-site construction, and reliable after-sales service.
We integrate high-quality products, one-stop project solutions, advanced engineering services, and international trade to deliver high-performance cooling systems.

A timeline of innovation, expansion, and dedication to global refrigeration standards since 1996.
Our founder started the business from refrigeration equipment marketing and installation.
With our first factory completed in Shaanxi, we produced our first cam-lock sandwich panels.
The second factory in LanZhou completed, our business started to cover the whole north-west market in China.
Following larger business and international demand, the Shaanxi factory relocated to a larger area, now possessing 120 acres with 8 advanced workshops.
With more advanced technology in insulation panel industry, we input our first automatic split-joint production line, beginning a new chapter.
Our second advanced automatic production line put on stream, reaching higher productivity and efficiency with better quality.
With the responsibility of sustainability, we are now moving into an eco-friendly factory, investing in green manufacturing practices.
How our refrigeration systems are configured to meet specific demands across diverse environments.
For fresh logistics and agricultural processing, maintaining correct relative humidity is vital. Our scroll systems control evaporation temperatures precisely to prevent food dehydration and weight loss.
Vaccines and biological agents require stable cold conditions. We deploy dual scroll compressor units with auto-switch loops, combined with thick PUR panels, to guarantee constant, reliable temperatures.
Modern retail stores demand quiet and energy-efficient systems. Using scroll compressors in variable frequency drives (VFD) cuts energy use by matching cooling output to the store's changing thermal load.
Large-scale hubs rely on high-capacity scroll racks or multi-compressor systems. Our solutions offer simple step-wise capacity control and maintain steady operation over long cooling lines.
Modern refrigeration is moving rapidly toward sustainable systems. Our engineering department is dedicated to adapting product designs for eco-friendly, high-efficiency operation.
Common questions answered by our application engineers and refrigeration experts.
Scroll compressors provide smoother continuous compression without using pistons or valves. This reduces sound, lowers vibration, minimizes the risk of liquid slugging, and increases volumetric efficiency because there is no clearance volume to cause re-expansion losses.
We employ 10 specialized Quality Control (QC) engineers who monitor the production line. From raw sheet metal and chemical foam preparation to compressor gas-leak tests, electrical insulation checks, and thermodynamic tests, every unit must pass our standards before export.
We manufacture PIR (Polyisocyanurate) and PU (Polyurethane) core sandwich panels. Polyurethane cores have very low thermal conductivity (approximately 0.022 W/m·K), which prevents heat ingress. PIR provides additional fire protection, which is essential to meet strict building codes.
Yes. Our FNH and FNV condensing units can be configured with genuine compressors from brands like Copeland, Bitzer, and RefComp, depending on project specs, capacity demands, and refrigerant choices.
We provide a complete engineering service from system design to installation support. We analyze the local climate, average humidity, and energy costs to design the best system, whether it is for a tropical region or a high-altitude location.
Electric defrost utilizes heating elements inside the evaporator coil, which is simple but consumes more energy. Hot fluorine defrost routes hot gas from the compressor discharge back through the evaporator, melting ice quickly and saving energy.
High ambient temperatures reduce the unit's capacity and increase power draw by raising head pressure. In hot climates, we configure larger condenser coils and high-velocity fans to ensure stable performance.
With regular maintenance, clean system piping, and correct oil levels, a high-quality scroll compressor can operate reliably for over 10 to 15 years.
Our automated lines produce sandwich panels with consistent structural foam density and high dimensional accuracy. This ensures tight joints when panels are connected on-site, preventing thermal leaks.
We provide full documentation for international exports, including certificates of origin, quality inspection reports, and customized packaging to ensure safe delivery across global ports.
Our commitment to manufacturing excellence is backed by recognized industrial certifications.
