Positive Displacement Gear Pump Ensure necessary oil supplied at variable speed, improve product reliability. Internal Oil Circulation Structure Low oil circulation rates (<2%) keeping oil in the compressor for superior reliability. Highly Reliable Bearings Cylindrical bearing and aligning ball bearing, better reliability. Bypass Valves Improved partial load efficiency with self-adapting variable pressure ratios for upgradedperformance - low ambient heating and high ambient cooling. Concentrated Motor Better performance at mid-low speed, lower winding height and less copper loss, more adaptable to APF condition. Non-contact Oil Membrane Oil film seals involute section of scroll set, reducing compression leakage for improved performance and lower sound. High Efficiency Motor Maintains high efficiency levels across wide speed range of 10-140 rps. Improved Asymmetric Wrap Additional displacement and superheat reduction for greater compressor efficiency. Gas Injection Technology Lower discharge temperatures, increasing capacity and expanded operating envelop for enhanced performance. High-Side Pressure Design Higher volumetric efficiency and improved oil management. Intermediate Gas Pressure Axial force is continually adapting, blending discharge pressure and compressed suction pressure for optimized performance throughout the operating envelop. Dynamic Oil Balance Structure Patented technology for unsurpassed oil balance in parallel piped systemoperation. Original Hitachi scroll design innovation
