Compressed Air Dryers

Compressed Air Dryers

Compressed air dryers are crucial for removing moisture from your compressed air system. Moisture can cause corrosion, product contamination, and reduced efficiency of pneumatic tools. By drying the air, dryers help prevent rust, clogged filters, and damage to sensitive equipment. They also ensure higher-quality end products in industries like pharmaceuticals, food processing, and electronics manufacturing.

Cycling Refrigerated Air Dryers
Cycling refrigerated air dryers use a thermal mass or refrigeration system that cycles on and off based on air demand, helping to conserve energy during periods of low load. These dryers maintain a consistent dew point while reducing power consumption when full capacity isn’t required. They’re ideal for operations that need to save on energy costs while ensuring consistently dry air. They are particularly suited for environments with fluctuating compressed air demand.

  • Flow Rate: 10 to 24,000 CFM
  • Pressure Dew Point: 33°F to 39°F (1°C to 4°C)
  • Operating Pressure: 90 to 150 psig
  • Input Power: 208V to 460V, 3-phase
  • Temperature Control: Cycles on/off based on demand
  • Ambient Temperature Range: 35°F to 115°F (1.6°C to 46°C)
Non-Cycling Refrigerated Air Dryers
Non-cycling refrigerated dryers deliver reliability with virtually no maintenance. Each dryer features a refrigeration system and heat exchanger that combines cool compressed air as it passes through it. They use a refrigeration circuit that stays on, maintaining a steady dew point and providing reliable moisture removal at all times. These dryers integrate a unique combination of components and features that ensure maximum productivity and longest service life at an affordable cost, best suited for applications with constant compressed air demand.

  • Flow Rate: 12 to 12,000 CFM
  • Pressure Dew Point: 33°F to 39°F (1°C to 4°C)
  • Operating Pressure: 90 to 150 psig
  • Input Power: 208V to 460V, 3-phase
  • Temperature Control: Constant operation
  • Ambient Temperature Range: 35°F to 115°F (1.6°C to 46°C)
Desiccant Air Dryers
Desiccant dryers are designed to remove moisture from compressed air by adsorbing water vapor onto a desiccant material, ensuring clean, dry air for sensitive applications. Heatless desiccant, heated desiccant, heated blown desiccant, and HOC (heat of compression) desiccant dryers are highly efficient in applications requiring extremely low dew points, typically in industries like pharmaceuticals, food processing, and electronics. These dryers are ideal for applications needing high air quality with ultra-low moisture levels, offering energy-efficient operation and reliable performance.

  • Flow Rate: 3 to 15,000 CFM (depending on technology)
  • Pressure Dew Point: As low as -40°F to -100°F (-40°C to -73°C)
  • Operating Pressure: 90 to 150 psig
  • Input Power: 208V to 480V, 3-phase
  • Regeneration Method: External heat, using electric or hot air for regeneration
  • Ambient Temperature Range: 35°F to 115°F (1.6°C to 46°C)
