New FSG i.HOC compressors feature IE4 motor.

Kaeser’s i.HOC dryers use the heat generated by compression to regenerate desiccant, eliminating the need for any additional energy in the drying process—even when air demand varies or in challenging environments. Full flow regeneration, along with an additional patented process, reliably provides pressure dewpoints to -22°F. The i.HOC oil-free compressors also feature a built-in heat recovery option and are designed to be space efficient without sacrificing serviceability.

FSG units come standard with Sigma Control 2™. This intelligent controller manages the entire drying process, while automatically adjusting to changes in air demand, maintaining consistent pressure dew points. Additionally, it offers unsurpassed compressor control and monitoring with enhanced communications capabilities for seamless integration into plant control/monitoring systems and the Internet of Things (IoT).
