Case Studies

Restricted Breathing Solution, UK Refinery

Requirement:

Supply zone 2 enclosures to house equipment for remote monitoring systems, to be installed in over 400 locations in one of Europe’s largest oil refineries.

Problem:

• The enclosures needed were cost and time sensitive as well as having to fit a pre-determined footprint.
• Flameproof enclosures (Ex d) were considered far too expensive, over engineered, cumbersome, heavy and unsuitable.
• The enclosure needed to house an uncertified switching in normal operation relay, as well as a PLC and other circuitry and components suitable for RTU.


One of Europe’s largest refineries goes remote control!

Solution

• indEx were able to mimic the exact footprint of the original enclosure and build a suitable sample for prototype use within 48 hours.
• indEx personnel have a wealth of experience and knowledge in providing bespoke solutions using Ex e (increased safety) junction enclosures and panels.
• For zone 2 indEx proposed the use of the zone 2 restricted breathing (Ex nR) protection concept.
