How to Choose the Right Heat Transfer Oil for the Heater / Cooler?
Heater/Cooler combines the two functions of high-temperature circulating oil bath and low-temperature coolant circulating pump. Its appearance greatly improves the experimental efficiency and saves space. It is a good choice for customers who require a wide range of temperatures. What can provide the heat source for the Heater/Cooler is to use the electric heating tube to heat the circulating fluid. The circulating medium includes water and oil, which can be selected according to the customer’s demand for temperature. The temperature of water has limitations, and the temperature difference is small, so most of them use heat transfer oil as the medium.
As we all know, heat transfer oil heats up quickly and has a high temperature, the highest can reach 300°C, and the lowest can be minus 120°C. It is an ideal choice for Heater/Cooler heat source and cold source. So how to choose heat transfer oil?
When users choose heat transfer oil, they mainly look at the following aspects:
1. The first is the fluidity of the heat transfer oil. The fluidity of the heat transfer oil is large, the circulation speed is fast, and the temperature rises quickly;
2. Secondly, the heat transfer oil should be selected according to the temperature. Below 250°C, generally choose mineral type heat transfer oil, when 250°C~300°C, you can choose alkylbenzene type heat transfer oil or mineral type heat transfer oil;
3. Then choose according to the region. In cold regions, you should choose heat transfer oil with good low temperature flow; if the instrument is to be operated continuously for a long time, you should choose heat transfer oil with high thermal stability.
In short, the choice of heat transfer oil should be selected according to its own environment. Because of the particularity of the heat transfer oil, it is a flammable and explosive item, so you must pay more attention to the storage, use, and regular replacement and maintenance of the heat transfer oil. Safety is the top priority of all work.
