The Hitachi NX2 series Oil-Flooded Rotary Screw Compressor, spanning 90-250kW, integrates advanced two-stage compression technology for exceptional energy efficiency and reliability. This system significantly reduces inter-rotor leakage by dividing compression into two stages and incorporates inter-stage cooling to decrease the load on the second airend, leading to substantial energy savings, such as up to 67,320kWh/year for a 90kW unit. Technical highlights include an optimally designed high-efficiency screw airend with robust heavy-duty bearings, an IP55 permanent magnet motor (IE4 equivalent for variable-speed models), and an intelligent LCD touchscreen control system for intuitive operation and comprehensive monitoring of parameters like discharge pressure and maintenance schedules. Available in both variable-speed (V-type) and fixed-speed (M-type) configurations, with air-cooled and water-cooled options, these compressors utilize dedicated NEW HISCREW OIL NEXT synthetic lubricant, extending service intervals up to 2 years or 12,000 hours, thereby lowering operational costs and ensuring stable, reliable performance across diverse industrial applications.
