TRBOCALL Switches Analogue to Digital for Major Petrochemical Company
02/10/2025
Eemits Communications has recently worked with a major petrochemical company to deliver an ultra-reliable two-way radio system by supporting the transition of analogue to digital in an ATEX environment.
The successful switch has been completed thanks to our award-winning modular platform TRBOCALL - which delivers cost-effective solutions via cloud-based technology and dedicated managed service support.
The challenge
A major petrochemical company operating a vast and complex facility in Teesside, UK, needed to update its current analogue two-way radio system as it was coming to an end of life - so a brand-new digital system was required to take advantage of greater channel capacity and modern safety features to aid its critical communications requirement.
With a high-risk operational environment, especially around key assets like jetties, reliable, robust, and clear communication is paramount.
Solution: Migration to a Motorola Capacity Plus Digital System
Eemits Communications designed and implemented a comprehensive digital transformation plan, migrating the site from its analogue system to a high-performance Motorola Capacity Plus Digital Mobile Radio (DMR) system.
This transition centred on the deployment of robust, ATEX-certified hardware to ensure safety in explosive atmospheres, alongside a full suite of managed services for maximum reliability and uptime.
Key Hardware Deployment
Handheld Radios: 46 x Motorola DP4401Ex ATEX radios were deployed. These intrinsically safe devices provide clear voice communications, essential safety features, and durability required for the demanding petrochemical environment.
Accessories: 15 x ATEX-certified Remote Speaker Microphones were supplied to allow workers to communicate easily and safely without needing to remove the radio from their belt, especially while wearing PPE.
Fixed Base Stations: 4 x Motorola DM4600e mobile radio units were strategically installed across the site at critical control points:
- Jetty 1a
- Jetty 2
- Jetty 3
- Gatehouse
This deployment ensures continuous, reliable communication coverage in these essential operational and security areas across the large Teesside facility.
Supporting the Transition
To ensure seamless operations during the migration period, Eemits provided a short-term hire of 20 ATEX radios, allowing the site to maintain full communication coverage while the new digital system was commissioned and deployed.
Service Wrap: A Full-Spectrum Managed Maintenance Programme
The client benefits from a comprehensive, multi-tiered service and maintenance package designed to guarantee maximum system availability and minimal disruption:
Eemits Hot Swap Maintenance: A rapid repair exchange service for critical infrastructure, including the Motorola SLR5500 repeaters, ensuring any faulty unit is immediately replaced to maintain network integrity.
Eemits Preventive Maintenance: A bi-annual two-day site visit by Eemits engineering teams to thoroughly inspect and check all manufacturer equipment, ensuring optimal coverage performance.
Reactive Maintenance: 24/7/365 Reactive Maintenance: Dedicated response and support for on-site infrastructure failure inside and outside of business hours.
Technical Support: 24/7/365 Telephone Technical Support for continuous assistance.
OFCOM Licence Management: Eemits manages the process of applying for and renewing OFCOM licences to ensure all regulatory requirements are met with operating licensed two-way radios.
Outcome: Enhanced Safety, Productivity, and Efficiency
The successful deployment of the Motorola Capacity Plus system by Eemits Communications has delivered a significant transformation in the petrochemical company's critical communications infrastructure:
Boosted Worker Safety: The ATEX-certified DP4401Ex radios and accessories provide intrinsically safe operation in hazardous zones, while the digital system's superior clarity and reliability ensure safety-critical messages are never missed.
Improved Productivity and Efficiency: The Capacity Plus system offers greater channel capacity and better coverage than the old analogue system, eliminating communication blackspots and allowing teams to coordinate operations more effectively.
Guaranteed Uptime: The robust Eemits Service Wrap, especially the Hot Swap and 24/7/365 reactive support, ensures the critical radio network is always operational, minimising costly downtime and maintaining business continuity.
By partnering with Eemits Communications, the petrochemical company has moved from an unreliable, outdated analogue system to a modern, intrinsically safe, and future-proof digital platform, delivering tangible improvements in worker safety, operational efficiency, and overall site productivity.
