Fully Custom Enclosure Service

Some projects call for special shapes and sizes of enclosures, non-standard features or very special applications, and may also require input from a Notified Body during the design phase or final certification.

With Expo’s fully custom process, a dedicated engineer will work with you to develop exactly what you need and agree on a detailed budget and project timeline with milestones. As this is a highly flexible service, we can adapt the plan if your project requirements change.

Depending on the scope, we can work with your team to install and integrate your equipment and hold factory acceptance testing for final sign-off

After the enclosure is populated and tested, Expo can manage the certification process directly, or work with a Notified Body if the scope falls outside of Expo’s populated certificates. 

Typical applications for Fully-Custom Enclosures

Expo has designed, manufactured and certified hundreds of enclosures for applications such as:

  • Complex electrical control panels
  • Drillers control panels
  • Hazardous gas and liquid analysers
  • Motor control / VFD panels
  • Extra-large / multi-section panels
