Industrial Combustion Engineering — A Rare Skill
Industrial combustion engineering is a declining trade. The engineers who genuinely understand DGF heating systems, industrial gas burners and process plant controls are increasingly rare — and when equipment fails in a production environment, the cost of downtime can be catastrophic.
EHL's combustion team carries decades of hands-on experience that cannot be replicated by a general FM contractor. We work predominantly across manufacturing, food production, logistics and process industries — environments where temperature is business-critical and a heating failure shuts the line.
Where we genuinely cannot repair, we say so — and we help you specify the right replacement. But in our experience, equipment is written off far too quickly by contractors who lack the skills to fix it. That's where we are different.

Process & Combustion — Full Scope of Works
Industrial Burner Servicing & Repair
Gas, oil and dual-fuel industrial burners. Annual servicing, combustion analysis, fault diagnosis and emergency breakdown repair for all major manufacturers.
DGF Unit Rebuild & Refurbishment
Specialist rebuild for PC Rapid, Niche and Nordair DGF units. In-house parts fabrication for obsolete components no longer available from manufacturers.
Combustion Analysis & Optimisation
Flue gas analysis, combustion efficiency testing and burner tuning to maximise thermal output and minimise fuel costs across your process plant.
Process Heating Systems
Planned and reactive maintenance for production-critical process heating systems. Minimising downtime in environments where every lost hour costs thousands.
PLC Controls & Instrumentation
Programming, fault diagnosis and repair of PLCs and building management systems integrated with combustion and process plant controls.
Gas Pressure & Flow Testing
Safety valve testing, gas pressure governor servicing, gas train inspection and flow testing for industrial plant operating at all pressure categories.
Why Choose EHL for Process & Combustion?
Rebuild Not Replace
We've saved single clients over £40,000 by rebuilding equipment that other contractors condemned. We fix what we can, transparently, and only recommend replacement when there's no better option.
CompEx Certified for Hazardous Areas
Qualified to work in potentially explosive atmospheres — essential for safe operation in industrial environments where other contractors cannot legally work.
One of the UK's Last Specialist Teams
Industrial combustion engineering is a dying trade. Our engineers carry decades of hands-on experience with DGF systems and process plant that simply cannot be found at a general FM contractor.
