Thermal fluid heating is an integral component of many industrial applications worldwide. These systems have mostly replaced boilers thanks to the flexibility and control thermal heating offers. With that said, it’s helpful to understand how they work. This post will examine how thermal fluid heating works and what products best facilitate it.
Thermal fluid heaters work by constantly circulating heat transfer fluids in a closed loop. This continuous flow provides a heat source that operators can access whenever necessary.
Operators of thermal fluid heating systems can vary fluid temperature through control loops. Generally, the thermal fluid must remain in liquid form to stay effective. However, some systems support vapour phases for applications where latent heat is better than simple heat.
The target object never directly interacts with the fluid heating system. As a result, operators have plenty of control regarding how they heat the object, especially when timing is of the essence.
Operators can use numerous heat transfer fluids in a thermal system. However, they must carefully choose the fluid for their application. That’s because different fluids behave differently based on their chemical composition. Operators use four key factors to determine what fluid is ideal for the system. They are:
Other factors may come into consideration. But these four — namely, temperature — are the main ones determining whether a fluid is suitable for the process. Some of these fluids are used in a variety of industrial applications.
The most effective fluids skew toward working within a wide temperature range. Some applications may allow for more than one type of heat transfer fluid.
Thermal fluid heating is a preferred method of heating for many reasons. It provides many advantages compared to other types of heating and can have some distinct benefits for your applications. Generally, thermal fluid heating systems are more efficient and stable than traditional boiler heaters.
Thermal fluid heating systems can look different depending on the type of fluid used and the application at stake. Most of these systems use a combination of pipes, flanges, valves, pumps, and other equipment.
Additionally, depending on the application, certain materials will work better than others. For example, we recommend steel piping if you’re using corrosive fluids. However, we will recommend the most suitable material for your particular operation and fluid selection.
