Choosing a fluid with the right thermal properties helps to ensure fluid longevity. Caldera Heat Transfer Fluids are made from high quality base stocks that maintain their thermal stability over an extended temperature range.

Other recommendations include the proper alignment of burner flame. A faulty flame disperser may cause the coils adjacent to the flames to absorb more heat energy than they can hold. Hence, a heat transfer fluid can be cracked if temperature at the tube surface exceeds the maximum bulk temperature.

Determine the spindle speed (RPM) and feed rate (IPM) for a drilling operation, as well as the cut time for a given cut length.

Thermal Cracking or degradation occurs when a fluid is heated above the maximum bulk temperature causing the covalent Carbon-Carbon bond to disintegrate into electrovalent bonds. This leads to the formation of molecules with lower molecular weights than the original molecule. Thermal cracking causes a reduction in viscosity, flash point, fire point and auto-ignition temperature. It is not uncommon to discover carbon varnish on the heat transfer surfaces. Typically, this is from a further disintegration of the Carbon-Hydrogen bond. In order to mitigate thermal cracking, it is important to understand ways in which fluid overheating can occur. They include wrong fluid selection, wrong flame impingement, improper startup & shutdown and a low flow regime.

Accordingly, during a shutdown of the system, heat must be decreased proportionately, in the reverse of the startup procedures. Keep the fluids circulating until system temperatures drop below the 200°F or 93°C mark, so that the residual heat is removed.

Operators should always start the pump before turning on the heater. This ensures fluid circulation and good mixing prior to heating. It also reduces the residence time of the fluid on the heated surfaces allowing for a steady rise in temperature, helping to prevent fluid cracking.

It is also sometimes helpful to check for plugged y-strainers and malfunctioning or improperly set bypass valves. This may free up some of the flow that may have been obstructed in the system. It is important that the fluids in heat transfers are circulating while the system operates at a high temperature.
