Cleaned plastic needs to be dried completely before further processing – even a small amount of moisture can stress the degassing systems. Thick-walled plastics are easy to dry. But thin film, with its extremely large surface area, presents a considerable challenge.

Pla.to Thermal Dryers achieve outstanding drying results by applying hot air to the wet plastic in a highly intensive process. The machine surfaces are thermally insulated to minimise heat losses.

The heat is generated through either

1. Gas or oil
2. Electric energy
3. Waste heat from technical processes such as diesel conversion

A heat exchanger is used to prevent the combustion gases from coming into contact with the plastic. This so-called indirect hot air generation provides optimal security against accidental fires.
