SF Subfreezing Dryers 360-1,600 m3/h, 210-940 cfm

The revolutionary SF dryer is the only regenerative refrigerated dryer available in the compressed air market today. It combines the subfreezing pressure dew point (PDP) of a typical regenerative desiccant dryer, with the low operating and energy costs of a refrigerated dryer, to provide an extremely low total cost of ownership. Best-in-class total cost of ownership, now with flow rates up to 1,600 m3/h

Features

  • ISO Class 3 high-quality air with a -20°C (-4°F) PDP delivered without interruption over the full range of compressor utilization (0-100%) 
  • Ideal for systems that have piping or pneumatic equipment exposed to subfreezing temperatures 
  • Patented heat exchanger design, with twin subfreezing chambers and a pre-cooler/ re-heater, provides a subfreezing PDP while reducing energy and operating costs 
  • No purge air required for regeneration, significantly improving energy efficiency 
  • No costly consumables such as drum wheels or desiccant wheels that require replacement, lowering maintenance costs 
  • Advanced controller ensures high air quality through an intuitive high-resolution display and remote connectivity to onboard web pages 
  • Plug-and-play, featuring a 40% smaller footprint and full compatibility with all compressor types without requiring any costly compressor modifications or downstream particulate filtration 
  • Smart solenoid drain valves actuate based on demand to ensure complete moisture removal during each cycle 
  • Compatible with any compressor technology without a costly investment, providing versatility for any application
