When building a compressed air system to work in potentially explosive atmospheres in the oil and gas industry, safety and reliability are essential

Having just one easy to use device managing all safety related signals was a significant advantage in implementing and maintaining Avelair's safe systems.


Avelair is an OE manufacturer of bespoke compressed air systems for many industries and applications. Their experienced technical team designs, builds, and tests all their systems in-house at their facility based in the UK.


Designing an ATEX compliant compressed air system, Avelair required a partner that could offer them comprehensive certification and documentation to enable them to complete a thorough robust safety lifecycle documentation package.




Matt Hart, a member of Avelair's technical team, explains why Avelair choose PR electronics as their partner and supplier for signal converting devices:

“PR electronics quickly identified our requirements for devices with full hardware and software SIL certification and full FMEDA to aid us in our own system failure analysis. They responded and supplied us with safety related signal converters that could be used in I.S. circuits and also a plain version that could be used in other safety related circuits."


Reduced training requirements and site commissioning times  

"Having just one easy-touse device managing all our safety related signals was a significant advantage in implementing and maintaining our safe systems, and significantly reduces the potential for systematic errors during these phases of the system lifecycle. The clear and easy way to set up the PR electronics devices with the fascia’s was a clear advantage as this reduced training requirements and site commissioning times”, Matt Hart says and concludes:

“We worked closely with PR electronics on this project. We both have the same value in that we want to ensure the safest reliable system possible. PR electronics helped us achieve this.
We now, have what we believe, is the safest, most reliable compressed air system for use in potentially explosive atmospheres on the market”.
