- 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.
