Engineered to deliver high volumetric efficiency, reliable thermal stability, and low energy operation across commercial cold storage ecosystems.
Founded on a legacy that dates back to 1996, Shaanxi YuanShengHeTong Refrigeration Equipment Co., Ltd. has established itself as an authoritative manufacturer and designer of insulation panels and high-efficiency refrigeration units. With over two decades of technical evolution, we offer global procurement teams one-stop cold storage solutions—spanning initial thermodynamics design, factory-direct manufacturing, installation engineering, and global export compliance.
We specialized in creating thermodynamic balance. Our core product portfolio, notably the 1.5 Hp Low Temperature Condensing Unit, is designed for demanding industries including commercial agriculture preservation, pharmaceutical cold chains, dairy logistics, hotel catering, and blast-freezing installations.
A comprehensive engineering breakdown of thermodynamics, gas dynamics, and structural efficiency built for extreme environments.
Incorporates highly reliable scroll or semi-hermetic reciprocating compressors. By matching displacement speeds with low evaporating temperatures (-25°C to -40°C), our 1.5 Hp units maintain optimal compression ratios, preventing internal overheating and early insulation degradation.
Featuring inner-grooved copper tube condensers and hydrophilic aluminum fins. This configuration increases the heat exchange surface area by 32%, ensuring rapid condensation under extreme ambient temperatures up to 43°C.
Equipped with dual-pressure controls (high/low pressure protection), phase sequence relays, compressor thermal relief valves, and liquid separator bypass lines, providing mechanical and electronic fail-safes.

Operating from our 60,000 m² state-of-the-art production base in Shaanxi, utilizing automated fabrication lines for maximum consistency.
Our facility runs four standardized heavy fabrication workshops containing CNC shearing machines, high-precision laser cutters, and automatic split-joint sandwich panel production lines. Having our own PUR/PIR sandwich panel press allows us to engineer complete, matched cold storage components under one roof. Our 10-member Quality Control team inspects each phase of manufacturing—from raw copper coils to automated gas leak detection systems using dry nitrogen and helium pressure tests.
By controlling the manufacturing pipeline of both the condensing units and the insulation panels, we eliminate structural mismatches, reduce thermal bridging, and optimize the total cost of ownership (TCO) for global distributors.
Our founder initiated business operations focusing on industrial refrigeration equipment marketing, localized installation, and maintenance services.
Completed construction of the first manufacturing facility in Shaanxi, pioneering the domestic production of high-density cam-lock sandwich panels.
Inaugurated our second factory in Lanzhou, extending our heavy industrial supply chain to service the northwestern China distribution market.
Relocated Shaanxi production to a modern 120-acre facility with eight advanced workshops to fulfill large-scale international OEM/ODM projects.
Commissioned our first automated continuous split-joint panel production line, ensuring micron-level precision and thermal consistency.
Integrated our second high-capacity automatic production line, optimizing manufacturing throughput and mechanical consistency.
Upgraded our system architecture to focus on zero-ODP, low-GWP refrigerants and eco-friendly raw insulation materials for global green initiatives.
How our 1.5 Hp low-temperature units synchronize with broader industrial and commercial cooling infrastructures.
Maintains high reliability inside specialized vaccine and medical product stores (2°C to 8°C or deep low temperature down to -25°C). Dual-compressor redundancy systems prevent temperature fluctuations during defrosting cycles.
Perfect for localized farm-side pre-cooling and storage chambers. When paired with our PUR Cam-Lock Sandwich Panels, it forms a sealed envelope that minimizes moisture loss in perishables, fruits, and vegetables.
Space-saving low-temp units are ideal for restaurant walk-in freezers. Their lower noise levels, combined with options for remote monitoring and electronic expansion valve integrations, suit high-density urban areas.
Anticipating regulatory changes and technological advancements to deliver long-term value for our clients.
In response to global regulations (F-Gas and Kigali Amendment), we are updating our 1.5 Hp compressor profiles to run efficiently on R448A/R449A and natural hydrocarbons like Propane (R290), achieving up to a 99% reduction in GWP.
Our upcoming product lines feature optional Modbus RTU interface cards and smart pressure transmitters. Operators can track suction/discharge temperatures, detect micro-leaks, and monitor compressor current draw via mobile apps.
By implementing DC inverter drivers in our 1.5 Hp units, we allow the cooling output to modulate dynamically between 30% and 120% load, reducing energy use by up to 25% during low-load operations.
We provide peace of mind through strict compliance, standardized quality checks, and local partnerships.
All refrigeration systems and electrical control enclosures leave our factory carrying CE certification, conforming to European LVD and EMC directives. Our PU/PIR sandwich panels are certified for fire resistance and insulation efficiency. We also assist partners in meeting regional import certifications, including SASO, SONCAP, and custom North American UL requirements.
To support global customers, we maintain close relationships with leading component manufacturers, allowing us to supply genuine parts like Copeland compressors, Danfoss expansion valves, and Carel controllers. We also keep a stock of critical spares (fans, solenoids, dryers) to support our distributors' regional service level agreements (SLAs).
Independent third-party verifications validating our quality management, structural integrity, and safety protocols.
Ensure structural integrity and cooling efficiency by matching our 1.5 Hp low-temperature condensing units with our certified panels and air coolers.
