Application Temperature Range: Primarily designed for low-temperature and deep-freezing applications, with a wide evaporation temperature range, typically from -45°C to -10°C (low-temperature), and extendable to medium-temperature ranges.
Top-tier Reliability and Durability • Robust and Sturdy Design: Utilizes high-strength cast iron for the body, crankcase, and large bearing structure, ensuring stable operation under extreme pressure differentials and loads, with a long design lifespan. • Advanced Lubrication System: Equipped with an efficient radial plunger oil pump that ensures sufficient and reliable forced lubrication for all critical friction surfaces under any operating orientation or condition, significantly reducing wear. • Durable Valve Technology: The ring valve design, combined with high-quality springs, provides faster response, higher flow efficiency, and excellent fatigue resistance, ensuring stable long-term operational efficiency.
Leading Energy Efficiency • High-Efficiency Motor Integration: Features Hitachi’s proprietary high-efficiency, low-startup current motors with high insulation class (typically Class F), perfectly matched with optimized compressor fluid components to achieve industry-leading energy efficiency ratios, significantly reducing operating costs. • Optimized Thermodynamic Design: Precision-machined cylinders, pistons, and flow paths maximize volumetric and isentropic efficiency, delivering outstanding energy performance, especially in low-temperature applications.
Ultra-Quiet, Low-Vibration Operation • Precision dynamically balanced crankshafts and built-in vibration damping designs effectively suppress operational vibrations. Optimized housing structure and internal noise reduction technology ensure exceptionally smooth and quiet compressor operation, reducing stress on system piping and installation foundations.
Broad Application Adaptability • Extensive Refrigerant Compatibility: Optimized for common medium- and low-temperature refrigerants such as R404A, R507, and R22, delivering excellent performance and meeting environmental regulations in global markets. • Wide Operating Range: Specifically optimized for low-temperature and quick-freezing applications, capable of reliable and efficient operation at extremely low evaporation temperatures (as low as -40°C or lower), while also covering medium-temperature application needs.
Global Professional Support • As part of Hitachi’s globally core product series, it benefits from a unified global spare parts supply network and professional technical support. The modular design facilitates on-site maintenance, minimizing downtime to the greatest extent.
