SNDC specialises in air treatment. The air we breathe and the comfort surrounding us are increasingly important for each and every one of us, whether at home or in our place of work: it is a question of health and well-being. Over and above comfort and well-being, two critical factors come into play regarding the operator's cabin in an agricultural machine, construction site machinery or industrial vehicle:

Health, through its long-term consequences from exposure to dust, pollution and toxic products (spreading and spraying)
Safety, linked to operator fatigue after several hours in an un-air-conditioned cabin

Designed to be simple to use, the HAVC system is nonetheless complete and complex. It reflects the use of a wide range of technical skills and standards.
