With Integrated Compressed Air Dryer 37 – 355 kW
The i.HOC (Integrated Heat of Compression) rotary dryer from KAESER offers energy-free compressed air drying by using up to 100% of the compressor’s waste heat. Designed for use in both air- and water-cooled oil-free rotary screw compressors, it ensures stable, sub-zero pressure dew points even under high ambient conditions – without requiring electric heaters or extra cooling systems. The i.HOC system is integrated with the SIGMA CONTROL 2 for smart monitoring and control.
- Consistent performance at partial load
- Efficient heat recovery built into the second-stage heat exchangers
- No need for additional heating or cooling equipment
