A high-efficiency screw compressor unit is the heartbeat of modern large-scale refrigeration. It provides the massive cooling capacity needed for cold storage, logistics hubs, and industrial processes. Backed by Luohe Tian Shun Cold Chain Group, Shanghai Heleng specializes in advanced refrigeration technology. We engineer and manufacture high-performance compressor packages tailored to your needs. Our systems ensure long-term stability, low vibration, and unmatched thermal efficiency for complex industrial setups.
Selecting the right configuration is critical for thermal efficiency and temperature stability in large refrigeration plants. We offer both single-stage and two-stage refrigeration systems to meet specific cold storage requirements. By matching the compressor style to the exact evaporating temperature, operators can minimize energy consumption. This approach also maximizes the lifespan of your refrigeration equipment.
Designed for standard low-and-medium temperature applications, the single-stage unit is the workhorse of cold chain logistics. These systems typically operate within evaporation temperatures from +10°C down to -30°C. They feature exceptional volumetric efficiency and simple mechanical structures. Combined with highly reliable oil separation systems, they are the optimal choice for standard cold room storage.
For deep freezing, blast freezing, and specialized industrial processes, a compound two-stage setup is essential. These advanced units use a dual-stage compression cycle to handle extreme pressure ratios safely. They can efficiently reach evaporation temperatures down to -70°C. Equipped with intermediate intercoolers and economizer circuits, these low-temperature packages excel in tunnel freezers. They perform reliably where standard systems would experience excessive discharge temperatures.
To guarantee maximum reliability, we integrate world-class components into every screw compressor unit we construct. Clients can choose from premium brands based on engineering preferences, budgets, and regional service networks. We proudly feature Bitzer compressors, renowned globally for their robust construction and exceptional endurance under heavy loads. For clients prioritizing superior cost-performance and advanced rotor profiles, our Fusheng units offer an excellent alternative. Additionally, we provide Heron compressor packages. These are ideal for custom-engineered industrial installations requiring precision capacity control.
Shanghai Heleng engineers our refrigeration systems with cutting-edge technology to deliver measurable operational savings. We focus on continuous optimization to give our clients a competitive edge. You can explore our engineering progress in our latest refrigeration technology updates.
Stepless Capacity Control: Smooth cooling adjustments from 10% to 100% perfectly match the real-time thermal load. This eliminates energy waste from frequent start-stop cycles.
Intelligent Microcomputer Control: Advanced PLC monitoring systems automatically track operating pressures, oil temperatures, and motor currents. This enables unattended safe operation and remote diagnostics.
Advanced Vibration Mitigation: Rigid structural steel bases and specialized isolation dampeners reduce mechanical noise. They also prevent physical wear on connecting refrigeration pipes.
Every industrial refrigeration system from Shanghai Heleng is configured with highly precise parameters. This ensures seamless integration into your project. Below is a general overview of our standard configuration options:
| Parameter / Model Type | Medium Temp Single-Stage Unit | Low Temp Two-Stage Unit |

Shanghai Heleng is more than just an equipment manufacturer. We are a dedicated, one-stop cold chain project partner. Backed by the robust manufacturing capabilities of Luohe Tian Shun Cold Chain Group, we deliver fully integrated solutions. From preliminary planning and budget calculations to custom fabrication, pipeline installation, and final commissioning, we handle it all. By coordinating our compressor systems with in-house insulated panels and evaporators, we ensure maximum system performance. This completely simplifies your procurement lifecycle.
The high-capacity performance of our heavy-duty industrial systems makes them the standard choice across many sectors. In the food processing and logistics industries, our equipment supports large-scale chilled distribution centers and automated meat processing facilities. For extreme deep-freeze needs, they provide continuous, high-volume cooling for tunnel freezers and IQF lines. Furthermore, our ultra-low temperature units are essential for freeze-drying operations and clean rooms. They easily maintain the exact environmental conditions required for delicate pharmaceutical manufacturing.
Single-stage units are optimized for medium-to-low temperature applications down to -30°C. In contrast, two-stage screw compressor units are engineered for ultra-low temperature requirements down to -70°C. They utilize higher compression ratios to provide improved efficiency under extreme conditions.
We design and assemble custom packages using top-tier compressor brands, including Bitzer, Fusheng, and Heron. This flexibility ensures we can align perfectly with your specific performance standards, regional support needs, and project budget.
Our units utilize stepless capacity control ranging from 10% to 100%. We also offer optional Variable-Speed Drives (VSD) to perfectly match the cooling load. This significantly reduces power consumption and prevents energy waste during part-load conditions.
Yes, absolutely. As a one-stop project partner, we manage the entire lifecycle of your cold storage facility. This includes system design, insulated panel manufacturing, piping installation, and final commissioning.
