Thermal fluid heating is a type of indirect heating in which the liquid heat transfer medium is circulated to one or more heat users. It is usually a closed loop system and the thermal oils or fluids are recirculated within the system piping. Thermal oil heaters carry heat to the heat users at user-set temperatures. Thermal oil has the capability of high-temperature operation (up to 600F with organic thermal oils and 800F with certain synthetics) – that too at very low pressures. However, because these fluids operate at extremely high temperatures and sometimes come in contact with atmospheric air, they get contaminated with carbon solds. These carbon solids build up and reduce the fluid’s heat carrying ability and the operating efficiency of the entire system. A common symptom of carbon or coking buildup is that the operating will not be able to accurately maintain process temperature.
Liquid Process Systems offers heat transfer fluid filtration systems designed to keep your industrial thermal fluid heating processes running efficiently and accurately. Our filtration systems are skid mounted, assembled and ready to install and use.
Here’s how you can measure the efficiency of your process fluids:
- Our stand-alone filtration systems (Sentinel model) includes a display on the control panel that monitors and shows percentage of filter clogging.
- When the filters are new and clean, the indicator displays “0” percent clogged.
- When the filter gets clogged with dirt and contaminants, the indicator displays “90” percent clogged. Then a flashing light comes “ON” indicating that there’s “10” percent life remaining on the element.
- When the display reaches “100” a light burns steady and the pump on the filter system shuts off, indicating that the filters are completely clogged with contaminants.
