• Micro dryer with capacity as low as 12 ounce (340 grams)
  • Available for compressed air or nitrogen drying
  • Suitable for medical-grade resins

Compressed air micro dryers from DRI-AIR Industries are now available with 12 ounce (340 grams) and 32 ounce (900 gram) capacity hoppers in addition to previously available 3-pound (1.4 kg) hopper.

Available for compressed air or nitrogen drying

Suitable for medical-grade resins, these dryers provide a continuous stream of low-dew point air and are available for compressed air or nitrogen drying. Compressed air dryers use a DRI-Pak membrane to assure dew points of -40°F (-40°C). Nitrogen dryers use bottled nitrogen or a factory nitrogen generator to achieve dew points of -80°F (-62°C), while also removing oxygen (in the drying process) as required for certain extremely oxygen or moisture sensitive resins.

Suitable for medical-grade resins

Clear-sight hoppers use butyrate plastic exteriors for insulation and are lined with Pyrex glass to eliminate contamination and for a clear view of material levels. All other contact surfaces are stainless steel which is necessary for medical molding. These hoppers have attached heaters that ensure precise temperature control from 80° to 400°F (27° to 204°C ) without the need for cooling water or special high-temperature process hoses. Their small size allows direct mounting on small extruders, micro molders, and 3-D printers without concern for moisture regain at drying levels below 50 PPM.

Founded in 1974, DRI-AIR Industries is a leading supplier of press-side and central resin drying, blending, and conveying systems. The systems are capable of drying even the most difficult-to-dry resins at rates from 1 to 3000 pounds per hour.
