Let’s go on speaking about thermoregulating units, and especially about a particular kind of heat transfer fluids, silicone based fluids. When they are employed?

First of all, let’s say these are highly expensive fluids. Compared to water or diathermic oil, they have a very higher cost. But there are some applications where it is necessary to employ them, because for example a process need to start from very low temperatures, where a mix of water and glicole becomes hard to handle because it becomes too much viscuous. Or even at too much high temperatures, where glicole water would start boiling and it’s not possible to pressurize the plant.

And so, we have to employ particular silicone based thermal transfer fluids, such as Therminol LT or Therminol D-12, that allow to work with very low temperatures and even with high temperatures, with atmospheric pressure circuits, and so not pressurized, but most of all, with a very low viscosity even at very low temperatures.

In fact, these heat transfer fluids keep a very smooth flowing at low temperatures allowing the use of pumps with relatively low power capacities and achieving an extremely efficient thermal transfer even at very low temperatures.
