Outstanding Energy Efficiency – Adopting advanced DC permanent-magnet motor technology, precision-machined valve plates, and optimized flow-path design, the E-series delivers excellent COP performance under medium- and low-temperature conditions. The E656DHD-65D2YG achieves a COP of 3.25, while the E405DHD series reaches 3.22. This means every 1 kW of electrical input produces more than 3.2 kW of cooling capacity, directly reducing energy costs and shortening payback time.
Wide Capacity Range – From the E405DHD at 36–42 cm³/rev to the E856DHD at 80 cm³/rev, the series offers a clear capacity gradient for precise system matching—avoiding both the waste of oversizing and the shortfall of undersizing.
DC Inverter and Wide Speed Range – Supports an operating range of 10–100 RPS. At part load it runs at lower speed to save energy; at peak demand it rapidly ramps up frequency to deliver strong cooling or heating. This design eliminates the mechanical stress and current surge caused by frequent start/stop cycling, extending service life.
Low Noise and Low Vibration – Optimized structure and precision manufacturing ensure quiet, smooth operation. The compact body design allows the E-series to fit easily into space-limited installation environments.
Robust and Durable – High-strength construction and premium components ensure reliable operation under continuous heavy-load conditions. The compressor is compatible with 3-phase 380–415V / 50Hz and 440V / 60Hz supplies, suiting markets worldwide.
