Plant Life Extension (PLEX) & Upgrade Support

Maximising Asset Value. Minimising Capital Expenditure.

In today’s industrial climate, the pressure to maintain high productivity while controlling costs has never been greater. Many facilities operate with “legacy” control systems that, while mechanically sound, are becoming increasingly difficult to support due to obsolete electronics and software.

At HF Automated Controls, we specialise in Plant Life Extension (PLEX). Our operational and upgrade support services are designed to revitalise your existing assets, integrating modern control intelligence into your current infrastructure to extend its operational life by years, or even decades. We bridge the gap between yesterday’s machinery and tomorrow’s technology.

Why Consider PLEX?

A full plant replacement is often disruptive and prohibitively expensive. Plant Life Extension offers a strategic alternative that delivers modern performance without the “new-build” price tag.

• Mitigating Obsolescence: We replace end-of-life PLCs, HMIs, and drives with current-generation hardware, ensuring spare parts are readily available and supportable.
• Enhanced Performance: Modern software algorithms can often extract higher speeds, better accuracy, and improved energy efficiency from your existing mechanical equipment.
• Data & Connectivity: PLEX allows us to “unlock” data from older machines, connecting them to your modern SCADA or cloud networks for real-time performance tracking.
• Sustainability: Extending the life of your existing machinery is a significantly “greener” option than decommissioning and disposal, reducing your facility’s carbon footprint.

Our Upgrade & Support Capabilities

We provide a comprehensive roadmap for upgrading your facility, from targeted component swaps to full-scale system overhauls.

Control System Migration

We specialise in migrating legacy control platforms (such as older Siemens, Rockwell, or Mitsubishi systems) to the latest high-speed processors. This includes rewriting and optimising software code to ensure a seamless transition.

Drive & Motion Refurbishment

Replacing outdated DC drives or early-generation AC inverters with modern, high-efficiency Variable Speed Drives (VSDs). This not only improves reliability but significantly reduces energy consumption.

Safety System Retrofitting

Upgrading your machinery to meet current UK safety legislation. We can integrate modern light curtains, laser scanners, and programmable safety controllers into your existing plant to ensure total compliance with modern standards.

24/7 Operational Support

An upgrade is only successful if it is supported. We offer bespoke maintenance and support agreements, providing you with priority access to our engineers and remote diagnostic support to ensure your “extended life” plant stays online.

Minimal Disruption, Maximum Return

The biggest fear with any upgrade is downtime. HF Automated Controls excels at Phased Upgrades. We work closely with your production teams to implement PLEX works during planned outages or in modular stages, ensuring your facility remains operational throughout the transition.

1. Asset Audit: We conduct a forensic review of your current systems to identify the “highest risk” obsolete components.
2. Strategy Development: We create a bespoke PLEX roadmap that fits your budget and production schedule.
3. Execution & Commissioning: Our engineers perform the upgrade, ensuring the “new” control logic perfectly matches the “old” mechanical movements.

Nationwide Support for Industrial Assets

From our regional hubs in Scotland, England, and Ireland, HF Group supports some of the UK’s most critical industrial infrastructure. We have the technical command required to take a system designed in the 1990s and make it perform to 2026 standards.
