Thermal Fluid Solutions & Industrial Heating


Consumes 20–50% Less Energy Than Steam

Thermal Fluid Engineering for Modern Industry

Steam boilers have long served many enterprises faithfully. But it must be acknowledged that steam as a heat carrier is expensive. Therefore, remaining loyal to steam boilers is not always a good decision.  


The use of thermal oil, unlike steam, is more economical. Companies familiar with this technology are convinced of the advantages of using oil as a heat transfer medium.


In the middle of the last century, thermal oil technology was economically unprofitable due to the low efficiency of oil heating furnaces, which exceeded the cost of electric heating. Today, modern boilers are used that run on gaseous or liquid fuel with an efficiency of up to 92%. Thermal oil (also known as high-temperature organic heat transfer fluid, or HTF) is a product of deep oil refining followed by distillation.

Thermal fluid vs steam: Why Choose Thermal Oil?

Thermal oil heating systems have revolutionized industrial heating for most industries, making large, energy-intensive production facilities that require a large number of people a thing of the past. Thermal oil heating systems are compact, easy to use, and provide overall energy savings that are hard to beat.


Unlike steam systems, thermal oil systems do not change the state of the fluid, so there is no condensation and, therefore, no steam losses, blowdown or make-up water losses, and no water discharge. Thermal oil systems are completely protected from corrosion and freezing and do not require expensive chemical treatment. In addition, users do not encounter the well-known problems of high pressure to achieve high temperatures. All this leads to significant cost savings during operation.

How Thermal Oil Heaters Function

Thermal oil heating is based on a principle similar to that of a simple hot water supply system. The system consists of a heater connected to carbon steel supply and return pipes and can simultaneously supply heat to one or more users or systems. Instead of water flowing through a closed pipe circuit, a heat transfer fluid that remains liquid throughout operation is used as the heat transfer medium. The heat of the fluid is transferred by turbulent flow at the heat exchange surface. The fluid then returns through a closed circuit to the heat transfer fluid heater for reheating, which occurs without further energy loss.

The operation of machinery such as presses, calenders, dryers, mixers, evaporators and so on requires thermal heating and/or cooling as part of the manufacturing process. This places various demands on the thermal oil system in terms of capacity, temperature, flow rate or pressure. All parameters are interrelated and require special attention to ensure a cost-effective, high-quality and sustainable system. Furthermore, specific regulatory requirements must be taken into account and incorporated into the planning.
