Hitachi Innovation of Air-End Technology
Stainless Steel Rotor
The rotor material, machined by high-precision grinding, is a special stainless steel that excels in corrosion resistance and durability. In addition, to minimize internal leakage, the rotor is mirror finished to ensure proper clearance, taking thermal expansion during operation into consideration.
High Performance Rotor Profile
Rotors exposed to discharge temperatures of 300°C or more in single-stage machines and 200°C or more in two-stage machines undergo significant thermal expansion. Hitachi’s own 3D compensation technology is applied to ensure that appropriate clearance is maintained during operation with thermal expansion.
High Performance Coating
The rotor is coated with a solid lubricant to further reduce gaps between rotors and improve performance. This solid lubricant coating has sufficient performance even in harsh environments of over 300°C. Hitachi’s unique technology is applied to this coating.
Multi-function Touch Screen
Cut Down Overhaul and Initial Cost
DSP single-stage has only one airend inside. It makes its initial cost much 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.*
Low Pressure with Higher Air Capacity
0.30MPa model is newly added
Vtype 0.30MPa and Fixed Speed Model 0.40MPa models are available for low pressure application to save the energy.
