Rajant IECEx-Certified Equipment Enables Communication in Explosive Environments

Located in southern Australia, a Victoria-based gas processing facility was dealing with the challenge of enabling continuous connectivity for workers inside the hazardous areas of the plant. Effective network access already existed in nonhazardous areas, but the owner wanted to extend connectivity into hazardous areas to provide Wi-Fi coverage for mobile workers who move between hazardous and nonhazardous areas.

In nonhazardous environments, communication is enabled using a basic transponder, receiver, and transmitter within the work area, but in facilities that include hazardous environments traditional access points —devices that connect to a LAN to provide Wi-Fi coverage—are not suitable. Equipment installed in hazardous areas must be certified for use in these conditions.

The Challenge

The plant owner wanted to ensure connectivity throughout the plant, but no provider had been able to deliver a simple solution to enable comprehensive coverage.

For access points to be used in the hazardous areas of a gas plant, they must be certified for sites classed as Zone 0 (areas where an explosive atmosphere is present continuously or frequently present) and Zone 1 (areas where an explosive atmosphere is likely to occur occasionally during normal operation). Most companies that could provide a solution use equipment that has to be certified for each installation, a time-consuming process that does not always deliver the best results.

RSN Solutions, a telecommunications and network Systems Integrator, was contracted to resolve this problem and deliver reliable wireless coverage for the entire gas processing facility.

According to RSN Solutions Director Gideon Parker, who managed the installation, the challenges on this project created a unique opportunity.

“This project was a “first” for both RSN and Rajant,” he said. This installation was Rajant and RSN’s first comprehensive wireless project for a hydrocarbon facility and the first to employ Rajant’s hazardous-area-certified wireless access points.

The Solution
RSN took on this project using the Rajant Kinetic Mesh® wireless network, which employs BreadCrumb® radios powered by InstaMesh® networking software to enable real-time data transfer. BreadCrumbs seamlessly integrate with any Wi-Fi or Ethernet-connected device to deliver low-latency, high-throughput data as well as voice and video applications across a meshed, self-healing network. Using Rajant’s Kinetic mesh network with the…
