Keep your cool or turn up the heat: Thermal equipment is in high demand in all sorts chemical and pharmaceutical processes. Heating and cooling systems provide precise temperature control and thermostating/tempering for reaction vessels, evaporators, dryers and filters. Of course, a lot of processes can rely on simple direct heating methods, yet the advantages of indirect heat transfer are multiple.

As several systems can be supplied with one single heater, a higher efficiency of the central heating system as well as reduced maintenance efforts and increased safety standards due to the separation between heater and consumer can be achieved.

Salt Beats Oil Beats Water

Indirect heating relies on thermal fluids to transfer heat or to cool down a vessel. While water may seem like the simplest solution, it has certain disadvantages such as the need to pressurize the whole plant if temperatures exceed 100 °C.

Thermal oils on the contrary can supply heat in a very wide temperature range almost without any pressure. Yet, in most demanding high temperature applications, also oils begin to show certain shortcomings, as they are limited to operating temperatures of around 400 °C.
