In 2001, SELLA CONTROLS was the first company to be awarded the CASS certificate for functional safety management, in compliance with the international safety standard IEC 61508.

This underlines our ongoing commitment to demonstrating the standard’s best practice, underpinned by SELLA CONTROLS’ principles of integrity, transparency and consistency.

The benefit to our clients is that we are in the best position to deliver cost-effective and compliant safety system solutions.
