What to Look Out for When You Choose A Heat Transfer Oil

The heat transfer oil is one of the most essential substances for high volume heat generation, particularly for the process industry. Heating and cooling have always been used for best results where steam and water are among the most common heat transfer mediums. However, water can reach its limit when the temperature reaches above 200 degrees Celsius. That’s when the systems must be pressurized, while requiring close monitoring to ensure safety.

Another problem with water is that it can cause pipes to corrode and affect other components of the system. Because of that, heat transfer oil filtration and minerals are considered viable alternatives. They are able to withstand temperatures from 200 to 400 degrees Celsius, and they do not have to be pressurized when temperatures reach 350 degrees Celsius.

There are two aspects to the side stream heat transfer fluid system. Reputable manufacturers carry different models for effective side stream filtration. They can help you pick the right system for your application while considering your capabilities to install it in the field. Here are some of the things you should consider when selecting the correct heat transfer oil: The basics The oil must meet certain criteria depending on the application. The key factors are good thermal stability, ease of waste disposal, reliable heat transfer properties, high flash point, and low viscosity. It should also be non-flammable, non-toxic, and non-corrosive.

You may want to consider key parameters such as viscosity, which must be at the lower end of a temperature range. Operating viscosity is responsible for the flow properties in pipes.

The right viscosity and the related turbulent flow should ensure proper heat transmission.

Thermal stability contributes to the efficiency of the pump and the heat transfer system’s safe operation. Because the oil is normally a mixture, heat transfer oil filtration may be conducted to eliminate constituents with a lower boiling point, as they can evaporate and affect the performance of the oil.

Anti-aging technology You will want to make sure that you are investing in a high-quality heat transfer oil that can be used for a long time. That will depend on the quality and type of the heat transfer fluid, but there are already products on the market that can be used for many years.

Keep in mind that the aging characteristics can depend on certain factors, such as the oil’s resistance to oxidation. Organic acids cause corrosion and are generated when oxygen reacts with saturated hydrocarbons. Polymerization products result in sticky deposits and sludge, while contaminants (i.e. rust, water, and dust) and copper enhance oxidation rate.

That said, heat transfer oil filtration may be considered.

Characteristics of the heat transfer You should also consider the heat transfer properties when selecting an appropriate fluid.

Heat conductivity is an indicator of the efficiency of heat transfer from film on a pipe wall to a flowing fluid. The medium for heat transfer must also be ideal for the system being used.

You can also check the vapor pressure at the end of the temperature range to determine if a system can operate without pressurization. Then, refer to the thermal expansion coefficient to see if the heat transfer medium is suitable to the expansion tank.
