High-Pressure Scroll Design Adopts Hitachi's patented high-pressure scroll structure. Lubrication is achieved through natural pressure differentials from high to medium pressure, eliminating the need for forced oiling mechanisms and reducing failure rates. The scroll plates feature high-precision asymmetric profiles with specialized wear-resistant treatment, combined with a forced lubrication system, ensuring long-term sealing and reliability.
Two-Stage Oil Separation Technology The compressor includes built-in oil separation functionality, supplemented by an additional oil separator in the system’s discharge circuit, achieving two-stage oil separation. This enhances system operational efficiency, stability, and reliability. The non-contact oil film sealing design relies on lubricant to form an oil film seal, reducing friction while improving efficiency and reliability.
Intelligent Protection System Equipped with a PTC motor protector from the German company KRIWAN, featuring a delay circuit that prevents compressor restart for 5 minutes after shutdown, effectively protecting the compressor. A safety pressure relief valve is installed between the high- and low-pressure chambers, and a PTC temperature sensor is directly inserted into the cylinder exhaust chamber, providing multiple layers of protection to ensure equipment safety.
