DSP Series Hitachi Oil Free Air Compressors
Range: 15 kW to 240 kW

Cut Down Overhaul and Initial Cost

Comparison of cost with the same air capacity level, because there is only one Air-End for DSP Single-Stage model, the initial cost is lower than Two-Stage model. The overhaul cost, which covers the most of maintenance cost, is about 60% of Two-Stage for the same reason.

* Example of Hitachi 55 kW (Single-Stage) and 45 kW (Two-Stage), Without Dryer model.

Expanded Line-Up (Low Pressure)

0.30MPa model is newly added. V-type 0.30 MPa fixed speed model 0.40 MPa models are available for low pressure application to save the energy.

Applications
In case that the pressure requirement is higher than blower but lower than standard compressor SPEC, low pressure specification DSP can be your solution.

IPC Control (Intelligent Pressure Control)

By estimating use point pressure in accordance with air consumption, IPC control decreases discharge pressure during low load operation, which enable Energy-Saving.

IT Communication Functions

USB Flash Memory Possible for Data Logging
Web Server Function via Bluetooth
Open Network serial communication Modbus /RTU is supported as standard.

Highly Reliability and Easy Maintenance

Totally enclosed flange motor is standard

New totally enclosed flange motor is applied to improve reliability.
Motor shaft in direct connection without coupling enables easy maintenance work.

High pre-cooler system (Air-Cooled Models)

High pre-cooler system reduces temperature of extremely hot air to after cooler and two-stage cooling structure improves reliability.

High Discharge Pressure Available

MPa is available with high reliability

Maintenance Friendly

DSP series provides easy accessibility for inspection and maintenance.

IPC Control (Intelligent Pressure Control)

By estimating use point pressure in accordance with air consumption, IPC control decreases discharge pressure during low load operation, which enable Energy-Saving.
