Thermal Fluid Heater Operation

Thermal fluid heaters, also known as hot oil heaters, are used to heat fluids in a closed loop system. They work by using a heat transfer fluid, typically a mineral oil or synthetic oil, that is heated by a burner. The heated fluid then circulates through a closed loop system, transferring heat to the target material or process.

Thermal fluid heaters are essential to the day-to-day operations of facilities in the asphalt industry, refinery industry, tank terminal industry, wastewater treatment industry, food and beverage, and beyond. Organizations in these, and other, industries rely heavily on thermal fluid heaters and hot oil heating systems to get the job done.

Unfortunately, many facilities are operating heating equipment that’s not as efficient or functional as it could be. As a result, they struggle with heating equipment breakdown and inefficiency, experiencing problems like process fluid degradation, tube failures, high stack temperatures (800° F or higher), high fuel costs, high maintenance costs, and limited operation at fluid temperatures over 400° F. Without systems operating at peak efficiency, they’re also experiencing significant decreases in profitability.

If any of the problems mentioned above are currently impacting your organization, it’s time to consider a high efficiency thermal fluid heater or heating system from Enerquip.

Serpentine Coil Technology

Enerquip’s serpentine coil heaters are synonymous with fuel efficiency. With a standard finned tube economizer section, efficiencies of up to 90% L.H.V. can be achieved without the use of air preheat.

Our customer-preferred serpentine coil thermal fluid heaters provide many enhancements over the more traditional helical coil heater, including:

  • Even heat distribution
  • Less oil degradation
  • Longer tube life
  • Higher operating oil temperature
  • Easy maintenance
  • Long-lasting

With today’s uncertain and often skyrocketing fuel costs, one of our units can pay for itself in a little more than one year when replacing an older, inefficient unit. Many of our customers have Enerquip thermal fluid heaters working hard for nearly 30 years! Learn more about the benefits of our innovative serpentine coil technology here.

Thermal Fluid Heater Applications

Industrial thermal fluid heaters from Enerquip can be utilized in a wide variety of applications and industries, some of which include:

Some organizations in these industries still rely on steam boilers to meet their industrial heating needs. If you are one of these organizations and you’re thinking of switching to thermal fluid heat, we highly recommend you make the switch. Find out why hot oil is better than steam for industrial heating.

Low NOx Heater Design

Enerquip has thermal fluid heaters in service with NOx levels of less than 9 PPM total NOx, and less than 50 PPM Co. We believe using flue gas recirculation is the most efficient way to achieve the lowest NOx level but we also use burner models that can achieve 9PPM NOx without a flue gas duct. Learn more about our efficient Low NOx heaters and heating systems.

Start-up Support

When it’s time to install your new industrial heater, rest assured you’re not in it alone. At Enerquip, we provide the full setup and startup support for our thermal fluid heaters and asphalt heaters. This includes a review of installed work and lines, supervision of the filling system, circulation of the oil, testing of circuits and safeties, bringing lines online, troubleshooting, and training on monitoring and operation of the system.
