Oil-free air compressors with integrated dryers

i.HOC® – Ultra efficient compressed air drying

The patented i.HOC® rotary drum dryer from KAESER uses up to 100 % of the compressor’s heat. Thanks to full-flow regeneration, it delivers reliable pressure dew points up to an ambient temperature of 115 °F – without electrical heating or additional cooling of the regeneration air.

• Available for air-cooled or water-cooled units
• Unit rated power from 50 hp to 450 hp
• Unit flow rates from 117 cfm to 1789 cfm
• Integrated SIGMA CONTROL 2 compressor controller

Your advantages

• Sub-zero pressure dew points even in high ambient temperatures:
   i.HOC® delivers below-zero pressure dew points even with high cooling medium temperatures.
• Pressure dew point stability even with variable flow rates:
  The pressure dew point remains stable even with low compressor load – no partial-load compensation required.
• Effective drying and heat recovery:
  i.HOC® uses the heat exchangers of the second compression stage, which have been optimized for heat recovery, as regeneration air coolers.
