Fabrication Questions
Can you build a C1D2 rated panel for hazardous oil and gas locations?
Yes. We design and build custom industrial control panels, and Class I Division 2 rated enclosure options are available from the hardware manufacturer for wellhead pads, tank batteries, and compressor stations. All panels are FAT-tested before shipping.
Can you connect the finished panel to Merobix?
Yes - that is the complete package. We program your PLC, build your panel, install the Merobix gateway, configure your tags and alert thresholds, and hand you a fully commissioned site live on the dashboard. One team, start to finish.
Do you offer on-site commissioning?
Yes. We provide on-site commissioning - our team comes to your location to get everything up and running. We also guide your local electrician through the installation every step of the way.

Services FAQ
Do you provide PLC programming services in the Permian Basin?
Yes - Merobix works with oil and gas operators across Texas and neighboring producing regions. We travel to your sites for commissioning and startup, and provide remote support for ongoing program changes and troubleshooting.
Which PLC brands does Merobix support?
We specialize in Allen-Bradley (Rockwell Automation) and Siemens platforms. We also work with a range of other major PLC and control-system manufacturers. Contact us with your specific hardware and we'll confirm compatibility.
How much does a control panel cost?
Every panel is custom-quoted to your specification - enclosure rating, PLC platform, I/O count, and drawings all drive the price, so we do not publish a standard price range. We provide free quotes based on your specifications - contact us at [email protected] or use the quote form above.
Do you offer remote PLC support and troubleshooting?
Yes. Most PLC troubleshooting and minor program changes can be done remotely via secure VPN connection to your PLC. For sites already connected to Merobix SCADA, our engineers can view live tags and diagnostics without a site visit, and most issues are resolved remotely - we aim to respond within one business day.
