Water-cooled oil-free air compressors

Compact energy-savers

Built for performance in demanding applications, our water-cooled oil-free compressors feature innovative cooling solutions to achieve the lowest possible power consumption.

This, in combination with a Kaeser heat recovery system, allows you to significantly reduce heating costs. Contact us for help tailoring a solution to your needs.

Their compact design and model-specific sized exhaust make them ideal for installations with low ceilings.

• Flow rates from 116 to 1790 cfm
• SFC models: available with Sigma Frequency Control, variable speed control (VSD) for superior part load performance
• CSG-2 series available with an integrated refrigerated dryer (T models)
• All models available with i.HOC® integrated heat of compression dryer

Your advantages

• Low compressed air discharge temperature:
  Cupronickel (CuNi10Fe) cooling pipes with internal star lamella fins provide optimum heat transfer.
• Lower costs thanks to heat recovery:
  With a Kaeser heat recovery system, up to 96% of compressor exhaust heat can be recycled – for example, to heat water to 195 °F.
• Maintenance-friendly:
  The air/water heat exchangers of the low and high pressure stages are housed in separate enclosures, each with large service doors for easy maintenance accessibility.
