Process heating, the heating and transferring of gases and liquids for industrial processes, encompasses various applications for specific purposes. This method looks similar regardless of industry, but some applications require specific heaters and system configurations. Therefore, knowing what devices are available for process heating is vital and how to choose the right units is vital.
The use of process heating is almost universal—most modern manufacturers rely on it in some fashion for their applications. Of course, process applications go beyond the manufacturing world.
Process heating is a staple method for these industries because of its advantages over heating methods. For example, it provides faster heating speeds, higher thermal efficiency, and reduced maintenance costs.
Like all forms of heating, the key factor for successful process heating is efficiency. The ultimate goal is to reduce heat loss. The more heat a process heating system retains, the more efficient it will be. The opposite is true, too. Inefficient process heating systems waste substantial amounts of heat. Additionally, inefficient process heating systems require larger heat outputs, which increases heating costs.
Ideal heaters and heating systems for process heating
Applications that rely on process heating are unique in that they depend mainly on two types of heaters—immersion heaters and circulation heaters, each having its advantages and disadvantages. Some process heating applications can use both within a single system.
Via their tubular electric elements, immersion heaters are submerged into the fluid (or gas) they deliver heat to, providing a direct stream of heat. The sheath elements in these heaters often contain corrosion-resistant material that can withstand high temperatures.
A benefit of immersion heaters for process heating is that almost all the energy they produce is used to heat their target fluid, which is the mark of great energy efficiency.
Here at Wattco, we produce a wide range of pre-built and customized immersion heaters which can service your process heating application. Components, such as watt density, sheath material, and dimensions, are customizable upon request, and we adjust them to suit the needs of your application.
Circulation heaters are often placed in a tube or pipe which delivers heat to gases or liquids that pass through it. The heater and tube are part of an enclosed loop that circulates the fluid. Circulation heaters typically need to be adjusted or fully customized for the application at hand. However, their nature makes them more versatile than immersion heaters.
Here at Watto, we produce customized circulation heaters for your process heating needs. We’ll consider your target fluid, its required temperature, and your heating system’s ideal orientation and placement.
Choosing the right device(s), whether it’s an immersion heater or a circulation heater, is just one aspect of maximizing process heating. It’s also important to maintain and customize your heating system appropriately. For example, that may mean insulating process heating components to prevent heat loss, which is the biggest cause of poor efficiency. Also, choosing the right material handling equipment is essential because it can also influence heat losses, either positively or negatively.
We customize immersion and circulation heaters to fit various process systems to ensure there’s minimal heat loss and power consumption. Whether you’re in the oil and gas or the packaging sector, you can rely on our heating solutions to meet your application’s demands.
