Introduction

Comet’s CHD-U series corrosion free stainless steel hot air hopper dryers can be directly mounted onto a molding machine for quick, space-saving drying or mounted to a floor stand with a take-off box. This dryer series is ideally suited to use with honeycomb matrix dehumidifiers to remove surface moisture from non-hygroscopic resins.

Model capacities range from 25 to 1,850 lbs. There are multiple optional accessories to meet different production demands, such as hot air recycler, magnetic base, and maintenance ladder, etc.

Features

• PID temperature control with LCD display and RS485 communication features accurate temperature control, digital display, and auto start/stop functions.
• Overheat protection ensures reliable operation.
• Unique, down-blowing air design ensures hot air is evenly distributed
  to maintain a steady temperature in the hopper and increase drying efficiency.
• Double layer insulated structure ensures a uniform temperature with less heat loss.
• All material contact surfaces are made of stainless steel.
• Over-heat protection ensures reliable operation.
• 7-day automatic timer and sight glass window.
• Models CHD-80U and above have a material clean-out door ensuring quick cleanup time and easy maintenance.
