Product Description Asymmetric vortex disk: Adopting Hitachi's patented vortex design, the double vortex disk engages in 180° staggered position to reduce gas leakage in the compression chamber, improve volumetric efficiency by ≥5%, and at the same time, reduce vibration noise. Wide working condition adaptability: Supporting -25℃ low-temperature startup, integrated EVI jet enthalpy technology, boosting low-temperature heating capacity by more than 25% through the intermediate make-up air to ensure stable operation in severe cold areas. Long-term reliability: Built-in multi-oil separation system (oil separation efficiency of 99.99%), combined with oil film sealing technology to reduce friction loss and extend service life to more than 100,000 hours.
Applications ● Commercial central air-conditioning multi-connected units ● High-temperature heat pumps ● Cold chain logistics refrigeration units
