Frequently Asked Questions
Q
What makes the high-pressure air-end in these compressors different from standard air-ends?
The air-end is purpose-built for high-pressure compression with an optimized rotor profile that minimizes internal leakage. It also features 8 bearings instead of the conventional arrangement, providing superior stability, precision, and a significantly longer service life even under continuous high-pressure operation.
Q
What discharge pressure range do these high-pressure screw compressors support?
The product lineup covers discharge pressures from 1.3 MPa up to 1.6 MPa (approximately 13–16 bar), making them suitable for applications requiring higher operating pressures than conventional industrial screw compressors. Please refer to the Technical Parameter table for model-specific pressure ratings.
Q
How does the IE5 oil-cooled permanent-magnet motor contribute to energy savings?
The IE5 oil-cooled PM motor operates across a wide speed range of 20%–110% with efficiency fluctuation below 4%. Combined with an advanced inverter and control algorithm for precise pressure regulation, the system continuously matches output to actual demand, eliminating wasteful unloaded running and maximizing energy savings under variable load conditions.
Q
Can these compressors operate reliably in hot or harsh environments?
Yes. The oversized cooling system provides more than 25% surplus cooling capacity, allowing reliable operation at ambient temperatures up to 46 °C. This prevents overheating and ensures consistent, stable performance even in demanding industrial environments with high ambient heat.
Q
How is air quality maintained throughout the compression and drying process?
SUS304 stainless-steel piping features a smooth interior to minimize pressure drop and prevent corrosion. The integrated high-efficiency aluminum-plate air dryer uses R410a refrigerant and achieves a stable dew point of 2–10 °C at the outlet, ensuring consistently clean, dry compressed air with lower lifecycle energy consumption.
Q
What control and monitoring features are included with these compressors?
Each unit is equipped with an Inovance heavy-duty inverter for precise speed control, the Deman Intelligent Control System with advanced high-pressure algorithms, a high-performance PLC compatible with mainstream communication protocols, and a 7-inch color touchscreen for intuitive data visualization and operation. Together, these components enable seamless monitoring, remote integration, and efficient day-to-day management.
