- With an inverter installed, total energy saving measures can be taken.
- The environmentally friendly water lubrication compressor without using oil at all (optimal for ISO 14000).
- Since water performs lubrication, sealing and cooling, high efficiency is achieved by ideal isothermal compression.
- Direct-coupled driving achieves the highest efficiency in its class, and the water lubrication saves maintenance work.
- Low noise, less vibration, slower rotation, and low temperature.
- Optimum for plants and large-scale factories.

By installing the latest IPM motor (internal permanent magnet motor) which contains a permanent magnet in the latest rotor, the compressor is made smaller and the rotation is made faster. If compared with conventional induction motors, the IPM motor does not cause electricity loss or slipping of the rotor, thus drastically enhances the motor efficiency. Combined with Mitsui Seiki's advanced inverter, the total efficiency also overrides that of single induction motors. Heat generation is reduced, leading to further energy saving. Also, the motor direct-coupled driving system eliminates the loss of power, improves the engagement and the machining accuracy of the compressor's main parts, and achieves the efficiency which is much higher than conventional machines. |
