The ATEX Directives

European ATEX Directives related to Machine Safety have been in place since July 2003.

  • We recommend safety audits and ATEX-compliance reviews



Coming largely from a mechanical or engineering background, most EO sterilizer manufacturers consider automation a side activity. At SOLSTEO, software is central to our performance and development strategy. Our SCADA system is a real added value for our customers.
