Thermal Cleaning

The process

In our pyrolytic oven all impurities and (residual) coatings are removed in a controlled manner with the aid of controlled heat. There are a number of reasons for cleaning metals or removing their coatings thermally.

 

There are several reasons clean or decoat metals thermally


  • Cleaning metal surfaces. Thermal cleaning is an option if the desired level of cleanliness is not achieved by blasting, or where blasting is too time-consuming.
  • Cleaning auxiliary tools. The (auxiliary) tools used in many production processes become soiled, such as auxiliary tools from which parts are suspended during coating processes, and parts in diverse processes that become soiled and regularly have to be cleaned.

Thermal cleaning takes place in a pyrolitic oven (LxWxH = 6 m x 2.5 m x 2.5 m). This type of oven has been specifically developed for this application. Coatings and impurities are dissolved in an oxygen-starved environment at a temperature of approximately 450 °C. The gasses generated in this oven are subsequently led to an afterburner where they are completely burned off at a temperature of 850 °C. Finally, the gasses are purified in an gas scrubber. Due to this exhaustive cleaning, wet and powder coatings, and fluoropolymers such as Halar® can be removed safely in an environmentally responsible way.
