A high-performance Scroll Compressor Unit forms the cornerstone of modern commercial and industrial refrigeration. It delivers exceptional thermal efficiency, low noise, and continuous mechanical stability. At Shanghai Heleng Refrigeration and Electromechanical Equipment Co., Ltd., we build these advanced systems to exacting standards. Our state-of-the-art Shanghai facility leverages the extensive resources of the Luohe Tian Shun Cold Chain Group. Our units utilize continuous orbital compression. This design reduces moving parts and minimizes vibration compared to traditional reciprocating systems. They remain the preferred choice for reliable, continuous cooling.
Whether your operations need medium-temperature preservation or deep low-temperature freezing, we customize our setups to match your exact parameters. We integrate cutting-edge design with intelligent manufacturing. This ensures every refrigeration unit provides optimal heat transfer. It also significantly reduces long-term energy costs for your facility.
To meet diverse global cold chain demands, we design and assemble an extensive lineup of equipment. Our flexible technical configurations include single-stage setups and split-type systems for space-restricted environments. We also offer advanced variable-frequency units that dynamically adjust capacity based on real-time thermal loads.
The table below provides a quick comparative overview of our standard configurations. Use it to identify the appropriate setup for your specific project needs.
| Unit Configuration Type | Temperature Range | Primary Refrigerants | Best Suited For |
|---|---|---|---|
| Standard Fixed-Speed Scroll | Medium to High Temp (-5°C to +15°C) | R404A, R134a, R448A | Commercial walk-in coolers, food prep rooms, and floral storage |
| Low-Temp Liquid-Injected Scroll | Low to Ultra-Low Temp (-40°C to -18°C) | R404A, R449A, R507 | Deep freeze rooms, seafood cold storage, and blast freezers |
| Variable Frequency Inverter Scroll | Dynamic Range (-30°C to +10°C) | R404A, R448A, R410A | Supermarkets, multi-room cold storage, and variable-load laboratories |
For operations looking to slash power bills, our energy-saving inverter models offer an intelligent solution. Standard fixed-speed systems constantly cycle on and off. This wastes start-up energy and causes temperature fluctuations. Instead, our variable-frequency systems dynamically adjust motor speed to match your real-time thermal load.
We pair these premium inverter compressors with electronic expansion valves and smart controllers. This allows our systems to maintain temperatures within a fraction of a degree. It also reduces overall energy consumption by up to 40%. This precise regulation is highly cost-effective for supermarkets and logistics centers. For buyers developing high-efficiency cold chain infrastructures, our professional refrigeration services seamlessly incorporate these inverter solutions.
Choosing the correct heat dissipation method maximizes the operational lifespan and efficiency of your refrigeration equipment. We offer both air-cooled and water-cooled configurations to suit your specific installation environment:
Air-Cooled Systems: These feature high-efficiency axial fans with low-noise motors and hydrophilic aluminum foil condenser coils. They require minimal maintenance and need no external water source. They are ideal for outdoor rooftops or well-ventilated ground spaces.
Water-Cooled Systems: We engineer these with premium shell-and-tube condensers to deliver exceptional heat exchange efficiency. They are best suited for high-ambient-temperature regions. They also work perfectly in indoor equipment rooms with existing cooling tower infrastructure.
HELENG Refrigeration delivers industrial-grade durability and outstanding energy ratings across our product range.

We source auxiliary components from industry-leading brands like Danfoss, Carel, and Alco. This approach ensures leak-free performance and precise system regulation across your entire cold room.
Refrigerant leaks often cause system failure and inflated operating costs. To eliminate this issue, our manufacturing plant utilizes advanced CNC-machined copper piping. By precision-bending copper tubes instead of using manual elbows, we remove up to 60% of traditional brazing joints. This dramatically reduces potential leak points over years of thermal expansion.
Our heavy-duty designs feature robust galvanized iron protective canopies. We finish these enclosures with a weather-proof, anti-corrosion powder coating. Combined with internal vibration isolators, this protective shell makes our outdoor units highly resilient. They easily withstand rain, snow, salt air, and extreme summer heat.
At HELENG, we go beyond supplying individual components to deliver comprehensive, integrated systems. We engineer our equipment to work perfectly with our customized polyurethane insulated panels, heavy-duty doors, and high-efficiency air coolers. This system-wide optimization ensures your cold room operates as a cohesive, highly insulated thermal envelope. It effectively eliminates cold bridge vulnerabilities.
We provide a complete, turn-key engineering experience. Our services range from initial thermal load calculations to shipping, installation guidance, and final commissioning.
