DuPont™ Vertrel® is a very effective heat transfer fluid. In evaporative cooling, Vertrel® is enclosed in a heat cycle system. When Vertrel® comes in contact with parts at high temperatures, it evaporates, cooling the parts. As Vertrel® moves to the cooler side of the heat exchanger system, it condenses back into liquid state. Vertrel® is used to continuously cool down the parts that could become damaged due to excessive heat.
In brine cooling, cold temperature Vertrel® is contacted with another fluid in a heat exchanger, effectively cooling the other fluid.
Vertrel® is used in applications such as Insulated Gate Bipolar Transistor (IGBT) modules and power semiconductors used in motors for the Shinkan-sen (bullet trains in Japan) and in the operation of express elevators.
Vertrel® specialty fluids offer the following benefits for Heat Transfer applications:
- Boiling point approximately 131°F (55°C)
- High latent heat, which allows Vertrel® to carry away large amounts of heat
- Thermal stability, which ensures that Vertrel® does not degrade, giving consistent cooling performance for years
- Chemically inert, which ensures that Vertrel® is compatible with the part being cooled
