Transforming Legacy Hot Oil Heaters Through Strategic Manufacturer Collaboration

New Hot Oil Heater Designed by Tulsa Heater Midstream (THM)

Hot Oil Heaters remain critical in many industrial and midstream facilities, yet many operate with outdated burners and control systems. These legacy setups often fall short of modern safety, reliability, and emissions standards. A recent project by Federal Thermal, in partnership with Tulsa Heaters Midstream (THM), demonstrates how close collaboration between heater manufacturers and controls specialists can successfully modernize these essential assets.

The Challenge of Aging Hot Oil Heaters

Legacy Hot Oil Heater to be Replaced

Many facilities rely on Hot Oil Heaters installed decades ago. Over time, the burners and control systems become outdated, leading to:

• Increased safety risks due to obsolete safety logic and interlocks

• Reduced reliability and frequent downtime

• Higher emissions that do not meet current regulations

• Difficulty integrating modern diagnostics and operator interfaces

  
  

Replacing entire heaters is costly and disruptive. Instead, upgrading the burner and control systems while preserving mechanical assets offers a practical path to extend service life and improve performance.

How Collaboration Drives Effective Modernization

Federal Thermal and Tulsa Heaters Midstream combined their expertise to address these challenges. THM contributed deep knowledge of heater design and mechanical systems, while Federal Thermal focused on burner management and control engineering.

This partnership enabled:

• Alignment of control philosophy with heater design intent

• Reduced integration risks during installation and startup

• Faster commissioning and improved operational efficiency

  
  

By treating the heater, burner, fuel train, and controls as one integrated system, the teams delivered a safer and more reliable solution tailored to real-world conditions.

Key Upgrades in the Modernization Project

The project included several critical improvements:

• Burner and combustion system upgrades to enhance fuel efficiency and reduce emissions

• Implementation of an NFPA-compliant Burner Management System (BMS) for improved safety

• Installation of dual safety shutoff valves and pressure supervision to prevent fuel leaks or overpressure

• Introduction of purge sequencing to clear combustible gases before ignition

• Development of protective shutdown logic that responds quickly to unsafe conditions

• Enhanced operator diagnostics for easier troubleshooting and maintenance

  
  

These upgrades not only meet current safety and emissions standards but also improve the heater’s reliability and ease of operation.

Benefits of Manufacturer-Control Specialist Partnerships ("Turn-Key" Solution)

Working directly with the heater manufacturer offers several advantages:

• Better integration: Controls are designed to match the heater’s mechanical characteristics

• Lower risk: Fewer surprises during startup and commissioning

• Preservation of assets: Existing mechanical components remain in use, reducing costs

• Tailored solutions: Controls and safety systems are customized to the facility’s operating conditions

• Ongoing support: Manufacturer and controls specialist can jointly support maintenance and future upgrades

  
  

This approach applies to both new heater projects and retrofits of older units, making it a versatile strategy for many facilities.

Extending Service Life and Reducing Operational Risk

Modernizing Hot Oil Heaters through collaboration extends the equipment’s service life by:

• Bringing safety systems up to current standards

• Improving system reliability and reducing unplanned shutdowns

• Enhancing operator confidence with better diagnostics and controls

• Lowering emissions to comply with environmental regulations

  
  

Facilities benefit from reduced operational risk and improved uptime without the expense and disruption of full heater replacement.

Moving Forward with Modernization

Sites operating legacy Hot Oil Heaters should consider a collaborative modernization approach. Partnering with both heater manufacturers and controls specialists ensures upgrades are well integrated and effective with their current systems.

Start by assessing your current heater’s condition and identifying key areas for improvement. Engage experts who understand both mechanical and control aspects to develop a comprehensive upgrade plan.

Modernization projects like the one completed by Federal Thermal and Tulsa Heaters Midstream show that with the right partnership, aging Hot Oil Heaters can be transformed into safer, more reliable, and environmentally compliant assets that continue to serve critical industrial needs.
