Maximum energy efficiency: HOC dryers use the heat already generated by the air compression process, which would normally be considered waste, making them the most energy efficient desiccant dryers on the market.
Reliability you can count on: High-performance switching valves, stainless steel heat exchangers, particulate post-filter and long-life desiccant provide clean air under the toughest conditions
Clean, Dry Air: Provides instrument quality air or air with a pressure dew point of -40°C (40°F) consistently under all load conditions
Intelligent Control: The user-friendly, full-featured controller automatically adapts the dryer to changing system demands to provide a consistent dew point
Easy maintenance: A low-profile design and easy access to components simplify installation and maintenance.
Heat of compression (HOC) dryers feature dual tower desiccant design technology and the most energy efficient design available for oil-free applications. HOC dryers recover heat that is a natural byproduct of the compression process to offset virtually all electrical costs except for those of operating the controller, which are equivalent to the negligible cost of turning on a light bulb. This dryer can provide instrument quality air as well as optional high quality air with a pressure dew point of -40°C (-40°F) at operating costs far below those of typical desiccant dryer designs.
