Frequently Asked Questions
-
QWhat makes the high-pressure air-end in the EHV/HV series different from a standard air compressor?The EHV/HV series uses a dedicated high-pressure air-end with an optimized rotor profile specifically engineered to minimize internal leakage under elevated pressure conditions. Combined with an 8-bearing support structure, it achieves superior operational stability and precision that standard air compressors cannot deliver at high-pressure outputs.
-
QWhat discharge pressure range is available for these high-pressure screw air compressors?The available discharge pressures across the product range are 1.3 MPa, 1.58 MPa, and 1.6 MPa, depending on the model selected. Models span from 11 kW to 37 kW drive power to suit a wide variety of industrial applications requiring elevated working pressures.
-
QHow does the IE5 oil-cooled permanent-magnet motor improve energy efficiency?The IE5 oil-cooled PM motor operates across a wide frequency range of 20–110%, maintaining high efficiency throughout the entire speed spectrum. Efficiency fluctuation is kept below 4%, which means energy savings are maximized even when operating under variable or partial load conditions—significantly reducing electricity costs over the compressor's lifecycle.
-
QCan the EHV/HV series operate reliably in high-temperature environments?Yes. The oversized cooling system provides more than 25% surplus cooling capacity above standard requirements, enabling consistent and reliable operation in ambient temperatures up to 46 °C. This makes the EHV/HV series well-suited for demanding industrial environments such as foundries, outdoor installations, and tropical climates.
-
QHow does the built-in aluminum-plate air dryer ensure consistent air quality?The high-efficiency aluminum-plate air dryer uses a 5 °C inlet-outlet temperature differential for pre-cooling to prevent secondary condensation. Using R410a refrigerant and a robust heat exchange design, it maintains a stable outlet dew point of 2–10 °C, delivering continuously clean and dry compressed air throughout the equipment's service life.
-
QWhat communication and control capabilities does the electric control system support?The electric control system integrates an Inovance heavy-duty inverter, a Deman intelligent control system with advanced high-pressure algorithms, and a high-performance PLC compatible with mainstream industrial communication protocols. A 7-inch color touchscreen provides an intuitive user interface for real-time monitoring, data visualization, and seamless integration into automated production lines.
