Thermal Fluid Filtration
The use of a thermal fluid filtration system helps to ensure a more cost effective, clean and efficient heat transfer system. Regular heat transfer fluid (HTF) testing and analysis will indicate a need for filtration. You can read more about our testing and analysis services and testing and analysis equipment.
All heat transfer fluids will degrade over time and if the fluid is left unattended, the by-products created during degradation can negatively impact the system. Debris can form from the internal pipes of the system, wear from pumps and fittings or from the oxidation of the fluid itself.
These solid particles can also cause fouling in the heat exchanger, which can lead to a reduction of heat transmission in heaters and machines, restrict flow and eventually wear down pumps, seals and valves.
If manufacturers do not monitor fluid and remove these particles efficiently it will impact the system and production. At the high operating temperatures required in many applications, the bonds that exist between hydrocarbon chains will start to break and form shorter (commonly referred to as ‘light ends’) and longer chained hydrocarbons (‘heavy ends’).
The build-up of light-end components is a potential fire risk because they decrease the ignition temperature of the HTF. You can read more about our Light Ends Removal Kit here. The accumulation of heavy ends results in the formation of sticky carbon deposits or sludge and can be monitored by analysing the carbon residue levels in a system operating with thermal fluid. If you have a problem with carbon build-up we can help with this too. Please call us on +44 (0) 1785 760 555 or contact us via email.

Investing in thermal fluid filtration can help you to operate a cost-effective system. Regular fluid monitoring and filtration will avoid downtime caused by seal wear on pumps and valves.
Thermal fluid filtration can also lead to energy savings. Carbon that forms in the degradation process cannot be heated. The system will over-compensate to maintain a constant temperature, increasing energy supply.
Regular fluid sampling and analysis can help to monitor fluid condition and extend its lifespan. Maintenance engineers should take a sample when the system is hot and circulating to get an accurate representation of what is happening inside the system.
Engineers can use the information from thermal fluid analysis to track fluid condition and plan for maintenance so that it does not impact production. Maintenance teams should also implement a thermal fluid maintenance programme such as Global Heat Transfer’s Thermocare. This service includes engineering support, fluid condition monitoring and analysis and technical advice to make sure that the facility and its processes meets DSEAR and ATEX regulations as well optimise system availability.
