Drywell Big Dry-Air Dryers

Granulate drying for high material throughputs


Big dry-air dryers of the Drywell series are specially developed granulate dryers with hopper volumes of up to 5.000 litres. These are primarily used in injection moulding and extrusion applications with high throughputs of plastic granulate. Depending on the application, these large-scale drying systems are installed next to the processing machine or above the screw intake or extruder.

Energy-efficient, Drywell big dry-air dryers

Drywell drying processes are based on the extremely energy-saving adsorption honeycomb principle. This drying technology ensures an adjustable, continuous dew point of the drying air. Together with the setting variables of drying temperature and air volume, drying processes with Drywell granulate dryers can be easily controlled. By adjusting and optimising the drying parameters, required residual moisture tolerances are maintained. The drying hoppers are characterised by the fact that both the inner and outer shells are made of stainless steel. This ensures that plastic granules only come into contact with stainless steel surfaces.

A thick-walled thermal insulation is inserted between the inner and outer shells of the drying hopper, which ensures that the process heat is retained in the hopper and not dissipated into the environment. This is another reason why Drywell pellet dryers are very energy-efficient. Plastic pellets are reliably kept dry in the Drywell pellet dryer.

Sizes of Drywell big dry-air dryers:

  • 1.200 / 1.500 Liter
  • 2.000 / 2.500 / 3.000 Liter
  • 3.500 / 4.000 / 5.000 Liter

Advantages of Drywell big dry-air dryers:

  • Constant dew point of the dry air
  • Easy set-up and operation
  • Drying time control, SmartMode
  • Optimisation of all drying parameters
  • Dust-free drying air thanks to desiccant rotor technology
  • Excess drying prevention: material is dried just right
  • No long and hot pipe connections, resulting in minimised energy losses
  • Low regeneration temperatures, gentle treatment of the dry air
  • No connections for compressed air and cooling water required

Options and accessories:

  • Bus interface
  • Visualisation and data recording
  • Operation via manual control unit
  • Conveyor system for feeding granulate dryers
  • Stainless steel quick couplings for the conveyor system
  • Exhaust ports in various diameters such as 50 mm, 60 mm or 70 mm

Project planning and service for large-scale drying plants

Together with our customers, the digicolor team of qualified and experienced specialists, technicians and engineers develops future-oriented, user-friendly and energy-efficient solutions – especially for pellet dryers with hopper volumes of up to 5,000 litres. In doing so, we always keep in mind the individual wishes, requirements and goals of our customers regarding the processability of plastic granulates in their production.
