Gaining the greatest efficiency out of your heat transfer system takes many things into account. By checking a few simple points and sizing the right filter, you can remove contaminants from the overall heating loop, increasing heat transfer efficiency.
In indirect heating systems, heat from combustion sources such as fuel or electric heating elements is transferred to the hot oil or thermal fluid. This heat is carried to the heat users or exchangers such as reactor jackets, calendar rolls, platens, molds and industrial fryers. The heating system provides the means to control temperatures precisely and to supply heat to the heat users from one primary heating unit or dedicated, multiple units.
All heat transfer oils are petroleum based, be they mineral or synthetic. When these oils are exposed to high temperatures, air or poorly designed circulation piping systems, the oil degrades. The byproducts of degradation are soot, carbon, coke and sludge that circulate through the overall process. These contaminants, which can be as minor as tiny floating particles or as large as thick blobs like road tar, foul the heat exchangers, heater elements or tubes, reducing overall heat transfer efficiency and leading to higher cost of operation, danger of fire and higher cost of maintenance.
