  • Page 62: Dryer

    CTT 1200 6.1. Dryer The dryer operates with dehumidified air, i.e. the air is not only heated but also dehumidified befo- re flowing into the drying hopper. This principle allows plastic granules to be dried to a residual moisture content as low as 0.002 % (PET granulate).

  • Page 63: Drying Hopper (Optional)

    CTT 1200 6.2. Drying hopper (optional) The material is dried in the drying hopper. The dehumidified air is forced through the material in the hopper, collecting moisture in the process. The drying hopper must be dimensioned according to its intended use to ensure that the final moisture content is attained. When the hopper is filled for the first time or at the start of a drying procedure, the material in the hopper must be dried com- pletely before material can be removed from the hopper for the first time.

  • Page 64: Return Air Cooler (Optional)

    CTT 1200 6.3. Return air cooler (optional) A return air cooler is generally required in cases in which the return air temperature is over 65 °C. A return air cooler improves the efficiency of the drying cells. The return air cooler reduces the return air temperature to a defined value.
