Oil-free Screw Compressors_DSP-NEXTⅡ Series Catalog

The Hitachi DSP-NEXTII Series Oil-Free Screw Compressors offer TÜV-certified Class 0 oil-free air, essential for industries like food & beverage, pharmaceuticals, and electronics. These advanced compressors feature durable stainless steel rotors, precisely machined with high-performance coating and 3D thermal expansion compensation for optimal clearance and longevity. Patented visco-type shaft seals effectively prevent oil leakage into the compression chamber, while special bearings and precision-finished timing gears ensure smooth operation. The series prioritizes energy efficiency through V-type (variable speed) models, Intelligent Pressure Control (IPC) that optimizes discharge pressure based on air consumption, ECO-MODE for automatic cut-out pressure reduction, and PQ wide mode for broader operating flexibility. Available in single-stage (15-55kW, 0.30-0.70 MPa, 2.0-8.5 m³/min) and two-stage (22-240kW, 0.70-1.0 MPa, 3.2-40.5 m³/min) configurations, they support both air-cooled and water-cooled options, with or without integrated dryers. Designed for high reliability, they maintain stable continuous operation in ambient temperatures up to 45°C and feature a user-friendly color touch screen interface with USB data logging, Bluetooth connectivity, and Modbus communication for easy monitoring and control. Simplified maintenance, including long overhaul periods and accessible components, further enhances their operational value, complemented by auxiliary equipment like air dryers, line filters, and multi-unit controllers for comprehensive air system management.
