How it Works

The main part of the Fluidbed Cleaning System is an insulated reactor containing sand particles. Sand is heated by a flame on the bed surface. The reactor is directly heated using a ‘flame-shield ’ at the bed surface in order to achieve temperatures around 450°C. Parts do not come directly into contact with flames.

Though not turbulent enough to be abrasive, the sand gently rubs the surface leaving the metal completely paint-free and undamaged. The fluidised sand ensures that the parts are subjected to an even temperature profile to avoid distortion.

Sand is heated by a flame on the bed surface. Parts to be cleaned do not come directly into contact with flames.

The paint is thermally degraded within the sand bed and the toxic gases are then oxidised at the bed surface using the ‘flameshield’. Inorganic particles are abraded by the sand particles and, blown out of the sand bed and captured in a filter system. Safe, clean, fast and environmentally friendly: words that are not normally associated with this type of cleaning!
