The ATEX Directives

European ATEX Directives related to Machine Safety have been in place since July 2003. The implementation of these regulations by EO sterilizers’ end-users requires detailed knowledge of the requirements. SOLSTEO always includes expert advice across projects to help MD manufacturers implement ATEX Directives at a factory level.

  • "We are very glad with our experience with SOLSTEO. Our contract was performed on time and without any problem in the middle of the holiday period so that volume production could restart immediately after the end of holidays. In spite of the very tight schedule SOLSTEO team has met all challenges and completed the contract with success."

  • "Nous avons intégré un stérilisateur OE de fabrication SOLSTEO dans notre usine en 2016. Le professionnalisme de l'équipe SOLSTEO, leur connaissance du procédé de stérilisation OE, leur réactivité (maintenance sur place et interventions à distance), les conseils et le savoir-faire ont largement contribué à faire de notre projet un réel succès. Nous sommes très fiers d'avoir sur notre site une technologie de pointe aussi fiable."
