Environmental protection

Fluorination is an environmentally friendly way of pre-treating surfaces:

  • to avoid waste-water flow,
  • to eliminate solvent-based paints and adhesives, and
  • to save energy thanks to low temperatures.

Fluorination systems do not emit any harmful substances. Gas-phase fluorination is a dry chemical process neutralising the fluorine mixture and the resulting byproducts directly within the process. Exhaust air is fed through an absorber containing calcium carbonate grit (CaCO3). Inside the absorber, the gas is converted into calcium fluoride (CaF2), also known as fluorspar, a frequently occurring mineral that is non-toxic, environmentally neutral and non-water-soluble. The calcium carbonate absorber is designed to comply with current legal limits as well as any limits to be expected in the future.
