Product overview

Power: 90A: 90 kW; 110W: 110 kW motor · Pressure: 0.75 / 0.86 / 1.0 MPaG · Flow: 90A: 16.4 / 13.9 / 13.4 m³/min

The official China DSP NEXT/NEXT II brochure dated August 2025 gives distinct air/water-cooled and fixed/variable-speed configurations. Its footer identifies Hitachi Global Air Power (Changshu) Co., Ltd. This existing product URL is a Hitachi catalogue reference; it does not confirm current manufacture in Nanjing.

At 50 Hz the fixed-speed air-cooled DSP-90A5N2 has a nominal 90 kW motor, with 16.4 / 13.9 / 13.4 m³/min at 0.75 / 0.86 / 1.0 MPa(G). Listed size is 2150 × 1520 × 1970 mm and mass 2130 kg. The fixed-speed water-cooled DSP-110W5N2 has nominal 110 kW, 20.8 / 18.0 / 17.2 m³/min at the same respective pressures, size 2150 × 1520 × 1820 mm and mass 2200 kg. Its cooling-water figure is 180 L/min, with inlet water ≤35°C. These are separate configurations, not one maximum-capacity machine.

Listed supply is 380/400/415 V, 50 Hz, with inlet ambient 0–45°C. Pressure is gauge and capacity refers to suction conditions. Motor rating is not total package input. Adjacent variable-speed columns and later DSP generations must not be substituted.

Specify process demand and pressure loss, reference flow, ambient/altitude, cooling utilities, electrical supply and control philosophy. Obtain a selected datasheet, package-input curve, installation and maintenance drawings, dryer/filter boundary and actual air-quality acceptance. The manufacturer's industrial-use cautions include no direct respiratory application. Confirm the manufacturing entity/location, destination conformity, commissioning, spares and warranty for the quoted order. The small original illustration is identified as a general DSP family view rather than an exact NEXT II model photograph.
