Frequently Asked Questions
What makes this high-pressure screw compressor different from standard compressors?
This compressor features a purpose-built high-pressure air-end with an optimized rotor profile and an 8-bearing design specifically engineered for continuous high-pressure operation. Combined with an IE5 oil-cooled permanent-magnet motor and an advanced inverter control system, it delivers superior reliability, efficiency, and precision that standard compressors cannot match.
What discharge pressure range do these compressors support?
The EHV and HV series models support discharge pressures of 1.3 MPa and 1.58–1.6 MPa, making them well-suited for demanding industrial applications that require consistently high output pressure.
Can this compressor operate reliably in high-temperature environments?
Yes. The oversized cooling system is designed with over 25% surplus cooling capacity, enabling reliable and stable operation in ambient temperatures up to 46°C. This makes it ideal for hot industrial environments such as foundries, chemical plants, and outdoor installations in tropical climates.
How does the integrated air dryer ensure air quality?
The high-efficiency aluminum-plate air dryer uses a 5°C inlet-outlet temperature difference for pre-cooling and R410a refrigerant to handle hot and humid conditions. Its heat exchange design with processing surplus maintains a consistent dew point of 2–10°C at the outlet, delivering clean, dry compressed air throughout the lifecycle.
What energy-saving features does the EHV/HV series offer?
The compressor uses an IE5 oil-cooled permanent-magnet motor with a wide operating frequency range of 20–110% and efficiency fluctuation below 4%. The advanced inverter and intelligent control algorithm provide precise pressure regulation, significantly reducing energy consumption under variable load conditions compared to fixed-speed alternatives.
What communication and control options are available for system integration?
The electric control system includes a high-performance PLC compatible with mainstream communication protocols, an Inovance heavy-duty inverter for precise speed control, and a Deman Intelligent Control System for advanced pressure management. A 7-inch color touchscreen provides an intuitive interface for monitoring and operation, making integration into existing industrial networks straightforward.
