Hitachi manufactures Single Stage VSD DSP Oil Free Rotary Screw Air Compressors.
Hitachi Single Stage VSD DSP Compressors Features
The Hitachi Single Stage VSD DSP Compressors offer the following features:
Purity of Air Compression
- Patented HX-18 PTFE-Free coatings ensure purity of air.
- Stainless steel rotors eliminate corrosion and promote the adhesion of the coatings.
Innovative Design
- Patented Rotor Profile Design optimizes the clearances for increased performance.
- Tapered rotors are utilized to compensate for the thermal expansion in the airend.
High Efficiency
- Matched HITACHI inverter and EPAct Efficiency motor allow for low power consumption and stable pressure control.
Maximized Thermal Efficiency
- Patented Stainless Steel Hi-Precooler assists in providing efficient cooling and thermal protection.
- The cooling air path of the Hi-Precooler maximizes thermal efficiency of the cooling system.
Environmentally Friendly
- Patented Oil Mist Remover (OMR) eliminates environmental oil emissions from the gear case, ensuring purity of air compression.
- By recapturing the vented oil mists, oil loss is minimal.
Increased Flow = Maximized Power
- Patented “PQ-Wide Mode” gives HITACHI the capability to adjust the speed of operation to provide greater output with lower pressure settings.
No Inlet Valve Design
- The patented no inlet valve design ensures that vacuum is not generated at the airend inlet and succeeds at obtaining stable sealing performance even at slow running speed.
- No rebuild or replacement parts are needed; saves investment in consumable and maintenance items.
HITACHI Microprocessor Based Control
- Lead/lag functionality is standard.
- Operational data recording is standard.
- Schedule Start/Stop operation is standard.
- Instantaneous Power Interruption (IPI) Restart Function is standard.
- PowerSave operation, which saves power by automatically decreasing the unload pressure and averaging the operating pressure is standard.
- Automatic Remote Air Dryer Pre-Start is standard.
Major Component Protection
- The standard Motorized Isolation Valve (MIV) automatically closes the discharge when the DSP air compressor stops, protecting major components.
Industry Leading Sound Levels & Vibration
- Quiet enclosure is standard.
- Low sound levels allow placement in a variety of locations
- Low vibration design minimizes leak paths.
Space Saving
- Hitachi manufactures the smallest oil free rotary screw air compressor package in overall dimension, allowing for easy placement in a variety of locations.
- Hitachi manufactures the smallest oil free rotary screw air compressor package in overall dimension, allowing for easy placement in a variety of locations.
- Panel accessibility promotes space conservation.
In-House Manufacturing
- Hitachi manufactures most of the major components of the DSP air compressors: HITACHI Airend, HITACHI EPAct Efficiency Motor, HITACHI Microprocessor Based Control and HITACHI Enclosure.
