AAC Gas are specialist industrial process burner engineers based in Higher Walton, Preston. Gas Safe registered and working exclusively in commercial and industrial environments, our engineers service, repair, commission, and certify gas-fired process burner equipment for manufacturers, food producers, automotive finishers, chemical processors, and industrial operators across Preston, Lancashire, Manchester, Merseyside, Cheshire, Cumbria, Yorkshire, and the wider North of England.

Industrial process burners operate under far more demanding conditions than space heating equipment — often running continuously, at high temperatures, with combustion requirements tied directly to product quality and production consistency. When a process burner fails, production stops. When it runs inefficiently, product quality suffers and gas costs rise. When it isn't properly maintained, it becomes a safety risk and a compliance liability.

Process Burner Services We Provide

Planned Maintenance & Annual Servicing

Regular planned maintenance is the most effective protection against unplanned process burner downtime. Every annual service includes:

• Full burner strip, inspection, and clean — combustion head, electrodes, nozzles, diffusers, refractory quarls, and all external components
• Ignition system testing — spark igniter, ignition transformer output, pilot burner operation, and full ignition sequence timing
• Flame safeguard relay and safety interlock testing — trial for ignition timing, flame failure response, and all safety device verification
• Gas valve testing and seat leak check — valve opening and closing times, proving pressure switch operation
• Combustion analysis and efficiency tuning — CO₂, O₂, CO, and flue gas temperature measured, air/fuel ratio tuned to optimum
• Flue gas testing — CO levels measured and recorded
• Refractory and burner tile inspection — combustion chamber condition assessed
• Gas pressure verification — supply and manifold pressures checked against manufacturer specifications
• Full written service report with combustion analysis data issued on completion

Emergency Fault Diagnosis & Repairs

When a process burner fails mid-production, fast and accurate diagnosis is critical. Our engineers carry comprehensive diagnostic equipment and commonly required spare parts to maximise first-visit repair rates.Common faults we diagnose and repair include:

• Ignition failure and repeated burner lockout
• Flame instability and combustion problems
• UV scanner and flame detector faults
• Gas valve failure — single and double-seated valves
• Flame safeguard relay faults — Honeywell, Siemens, Kromschröder, Dungs, Fireye, Autoflame
• Combustion air fan failure — motor, drive, and VSD faults
• Modulation and control system faults
• Refractory deterioration and combustion chamber damage
• Gas pressure switch and proving system faults

Commissioning & Recommissioning

New process burner installations, equipment relocations, production line changes, and post-maintenance restarts all require proper commissioning. We commission and recommission gas-fired process burners across the North of England including:

• Gas pressure setting and verification
• Combustion calibration to specification
• Full safety interlock operation verification
• Gas safety certification on completion
• Full commissioning documentation

Combustion Analysis & Efficiency Optimisation

For energy-intensive process operations, combustion efficiency has a direct and measurable impact on gas consumption and running costs. The difference between a poorly tuned process burner running at 72% thermal efficiency and one tuned to 91% efficiency is significant — particularly for continuous-operation equipment running through a full production year.Our engineers carry calibrated flue gas analysers on every visit and tune burners to optimal performance as standard.

Gas Safety Certification for Process Equipment

Industrial process burner installations require gas safety inspection and certification under the Gas Safety (Installation and Use) Regulations 1998, the Health and Safety at Work Act 1974, and PUWER. We issue full gas safety certification and provide clearly documented records ready for:

• Insurance audits
• HSE inspections
• Internal health and safety management systems
• PUWER compliance records

Process Equipment We Service

Powder Coating Curing Ovens

Powder coating curing ovens require precisely controlled gas-fired heat — typically between 160°C and 200°C — to fuse coating materials onto metal substrates. Temperature consistency is critical to finish quality. A poorly tuned burner produces uneven cures, outgassing defects, and significant product reject rates.We service, repair, and commission powder coating oven burners across the North of England — covering batch ovens, conveyor ovens, and all custom process oven configurations.

Spray Booth Make-Up Air Burners

Spray booth gas-fired make-up air burners heat the incoming air supply to maintain booth temperature and air velocity during coating application. A failed spray booth burner directly affects finish quality, throughput, and operator safety.We service, repair, and commission spray booth burner systems across the North of England — covering all major configurations including direct-fired and indirect-fired make-up air heaters, and re-circulation systems.

Bakery & Food Production Ovens

We service, repair, and commission gas-fired bakery and food production oven burners including:

• Tunnel ovens — continuous belt ovens used in high-volume bread, biscuit, cracker, and cake production
• Deck ovens — traditional baker's deck ovens including steam injection systems
• Rack ovens and rotary rack ovens — high-capacity batch baking ovens
• Travelling ovens — specialist continuous ovens for biscuit and cracker production
• Indirect-fired batch ovens — used across food manufacturing for baking, roasting, and drying

We understand the food safety and hygiene requirements of food production environments and work to minimise disruption to production schedules.

Pasteurisers & Sterilisation Systems

Gas-fired pasteurisers and sterilisation systems in food and beverage production, dairy processing, and pharmaceutical manufacturing require precise temperature control and reliable combustion to meet food safety and regulatory requirements.

Industrial Rotary Dryers

Gas-fired rotary dryers used across aggregates, minerals, food manufacturing, agricultural drying, and general industrial processing. We service and maintain rotary dryer burner systems — including high-momentum burners, swirl burners, and multi-fuel configurations.

Fluid Bed Dryers

Fluid bed drying systems used in pharmaceutical manufacturing, food production, and chemical processing. We service fluid bed dryer burner systems with particular experience in pharmaceutical and food production environments where GMP-aware working practices are required.

Spray Dryers

Gas-fired spray drying systems used in dairy, food, chemical, and pharmaceutical manufacturing. We service and maintain spray dryer burner systems across the North of England.

Laundry Tunnel Finishers & Dryers

Gas-fired tunnel finishers and industrial laundry dryers used in commercial laundries, hotel laundry operations, and NHS laundry facilities. Brands covered include Kannegiesser, Jensen, Girbau, Electrolux Professional, and Miele Professional.

Grain & Agricultural Dryers

Gas-fired and LPG-fired grain dryers and agricultural crop dryers across Lancashire, Cumbria, and Yorkshire. LPG qualified for rural and off-grid agricultural installations.

Chemical & Petrochemical Fired Heaters

Gas-fired fired heaters in chemical and petrochemical process operations across the Runcorn, Northwich, and Ellesmere Port chemical corridor. We work to the safety requirements required for chemical manufacturing environments.
