The concept and uses of heat transfer fluid

1.What is heat transfer fluid?

heat transfer fluid is a common name for organic heat transfer fluids, also sometimes called heat transfer fluid, organic heat carrier, heat medium oil, or heat conduction oil. It is a medium that transfers heat in liquid or gas phase. It includes mineral-based heat transfer fluids and synthetic heat transfer fluids. Mineral-based heat transfer fluids are called heat conduction oils; synthetic heat transfer fluids are called heat conduction fluids.

2. How are mineral-based and synthetic heat transfer fluids produced?

Mineral-based heat transfer fluids are produced by extracting a fraction of petroleum product during petroleum processing, refining it, and then adding various additives. Synthetic heat transfer fluids are produced using chemical or petrochemical products as raw materials through organic synthesis processes. Synthetic heat transfer fluids are pure or relatively pure chemicals, and compared to mineral-based heat transfer fluids, they have advantages such as better thermal stability, higher operating temperature, longer service life, and regenerability.

3.What are the uses of heat transfer fluid? In which industries is it mainly used?

    Compared with steam heating, heat transfer fluid has advantages such as uniform heating, simple operation, safety and environmental protection, energy saving, high temperature control accuracy, and low operating pressure. Therefore, it has been widely used as a heat transfer medium in modern industrial production.

In the maritime industry, heat transfer fluid is mainly used for heating heavy oil tanks, asphalt tanks, sulfur tanks, and containers that require heating and insulation on ships.

In addition to the industries mentioned above, heat transfer fluid can also be used in hot water generators, steam generators, radiators, and for heating in the soap and detergent industry, tar processing industry, and laundry industry.

Because heat transfer fluid is an excellent heat transfer medium, capable of both heating and cooling, and serving as both a heating and cooling medium, it is increasingly recognized and widely used in modern industrial production due to its advantages such as uniform heat transfer, simple operation, safety and environmental protection, energy saving, ability to achieve high temperatures at lower pressures, lower equipment requirements than steam boilers, and lack of geographical limitations.

MAXTOP heat transfer fluid uses 99.9% high-purity chemically synthesized base oil and incorporates MAXTOP’s self-developed composite additives. It employs multiple patented formulation technologies and is developed through several self-developed, ultra-long-term anti-coking tests subjected to both high temperatures and oxidation. Commercially available chemically synthesized heat transfer fluids generally do not contain any additives and are prone to thickening and gelling (coking) when exposed to oxygen during use. However, MAXTOP self-developed additive system does not produce these problems .
