Oil free centrifugal compressors designed for efficiency

The components of the oil-free centrifugal compressors have been carefully designed in house. This reduces losses and pressure drop to a minimum, resulting in the highest compressor package efficiency. Our oil less compressors are also class 0 certified, delivering the highest air purity at the lowest total cost of ownership. By using our state of the art centrifugal compressor technologies you're guaranteed to a reliable and efficient compressor.

Recover your energy

You can turn your centrifugal air compressors into an energy source. By adding an Energy Recovery unit you will be one step closer to achieving your goals in becoming carbon neutral. Up to 94% of the electrical energy is converted into compression heat.

Without energy recovery, this heat is lost in the atmosphere via the cooling system and radiation. Our energy recovery unit uses compression heat to heat up water. This warm water can be used for sanitary purposes, space heating, or process applications.

Save energy with smart technology

Our compressor monitoring system saves energy by using advanced control algorithms. The dual pressure band can lower the pressure in your system during e.g. weekends and night shifts. Our Elektronikon® controller is the brain of the compressor collecting data for optimal energy efficiency.

Monitor your system

It's important to know the status of your compressed air installation. With the Elektronikon® you can easily connect your controller with your mobile devices such as tablets and smartphones. Our SMARTLINK system allows mobile monitoring over a secure network. Monitoring your system not only saves you money but also avoids breakdowns and production losses.
