Metal cleaning



“ Every individual has the power to make the world a better place.” - S. Bambarèn

Our philosophy is to put the environment and respect for nature at the centre of our work.

All our machines are equipped with an efficient extraction system and are insulated from the outside, thus eliminating any dust or agents that are harmful to our atmosphere.

We have implemented several systems to prevent pollution and advanced abatement systems that purify atmospheric emissions and purify waste water that are constantly monitored by computerised instrumentation.
