Heavy-Duty Reciprocating Compressor Unit

 
Semi-hermetic reciprocating compressors are widely used in cold storage and industrial refrigeration. They feature a motor and compressor enclosed in a single housing with serviceable openings. Utilizing piston technology, these compressors support various refrigerants (e.g., R404A, R134a, R407C) and operate at medium to low evaporation temperatures (e.g., -40°C to -12.2°C). Known for high efficiency and reliability, they often include motor protection and oil monitoring, making them suitable for freezing, refrigeration, and food processing applications.

◆◆ Product Advantage

  • Exceptional Energy Efficiency & Reliability

    Our semi-hermetic compressors are engineered for superior cooling performance and long-term durability. Featuring optimized piston and valve design, they achieve high Energy Efficiency Ratio (EER), significantly reducing operational costs. Robust construction ensures stable operation even under heavy loads and extreme temperature conditions, providing dependable performance for critical cold storage applications.


  • Broad Refrigerant Compatibility

    Designed for versatility, these units support a wide range of eco-friendly refrigerants including R404A, R407C, R134a, and R448A. This flexibility allows seamless integration into existing systems and compliance with evolving environmental regulations, making them a future-proof investment for sustainable refrigeration solutions.


  • Intelligent Protection & Monitoring System

    Integrated advanced safeguards include motor protection, oil pressure monitoring, and phase reversal protection. These features prevent costly downtime and compressor damage by automatically shutting down the unit during abnormal conditions, ensuring operational safety and extending the equipment's service life.


  • Low Noise & Vibration Operation

    Through precision engineering with balanced crankshafts and advanced mufflers, our compressors operate with significantly reduced vibration and noise levels. This creates a better working environment and minimizes structural transmission, simplifying installation requirements and enhancing overall system stability.



  • Easy Maintenance & Service Support

    The semi-hermetic design allows for essential repairs and maintenance without entire system replacement. With readily accessible components and global technical support network, we ensure minimal downtime. Our units feature easy-access service valves and oil sight glasses for simplified routine checks.


  • High-Performance Motor Technology

    Equipped with high-torque, encapsulated motors designed for reliable starts in low-temperature environments. These motors feature special insulation coatings resistant to refrigerant and oil, ensuring optimal electrical efficiency and thermal performance under continuous operation.


◆◆ Product Uses

  • Large-Scale Food Freezing & Cold Storage Warehouses

    These compressors serve as the core equipment for large-scale cold chain logistics centers and food distribution warehouses. With powerful cooling capacity and reliability, they are ideal for maintaining stable low temperatures in freezing warehouses (-25°C to -18°C) and cold storage rooms (0°C to 4°C), ensuring long-term preservation of meat, seafood, and frozen products.


  • Food Processing & Industrial Cooling Applications

    Widely used in food processing plants for blast freezers, IQF (Individual Quick Freezing) tunnels, plate freezers, and low-temperature processing workshops. They enable rapid temperature reduction, preserving flavor and nutritional value while meeting demanding cooling requirements in food production processes.


  • Commercial Supermarket Refrigeration Systems

    Provide reliable cooling for open refrigerated display cases, beverage coolers, and backroom cold storage in supermarkets and convenience stores. Their stable operation and high energy efficiency help retailers effectively manage operational costs while maintaining optimal product display conditions.


  • Hotel Catering & Central Kitchen Refrigeration

    Ideal solution for large cold rooms and refrigerated workstations in hotel kitchens, central food preparation facilities, and restaurant operations. Their compact design and powerful cooling performance meet the industry's demanding requirements for ingredient freshness, high turnover, and hygiene standards.


  • Logistics Pre-Cooling & Temporary Storage Solutions

    Provide rapid cooling for container pre-cooling stations and transit cold storage facilities at logistics hubs including ports, airports, and freight terminals. Ensure temperature-sensitive goods maintain required low temperatures during transfer and temporary storage before transportation.


  • Low-Temperature Environments for Slaughterhouses

    Deliver precise temperature control for cooling carcass chilling rooms, meat cutting areas, and frozen packaging sections in slaughterhouses and meat processing facilities. Maintain strict temperature standards (0-4°C for aging processes and -18°C for freezing) to ensure product quality and safety compliance.
