High flash point oil avoids hazardous situations

04 September 2016

Thermal Fluid Solutions (TFS) has launched a food grade TFS Thermaltrans FGS – a semi-synthetic heat transfer fluid with a closed-cup flash point of over 260°C which allows it to be used safely in systems operating at a bulk (highest average) temperature of up to 300°C and film (container boundary) temperature of up to 325°C. 

A fluid’s flash point is the minimum temperature at which, in the presence of ignition sources, such as light switches, pump failure or sparks, its vapours will ignite and it becomes classified as hazardous. The chemical composition of the oil ensures a good level of stability, allowing it to resist for longer the process of degradation and consequent flash point reduction. The fluid creates a minimum of carbon deposits and varnishes. It is also resistant to water contamination.

Commenting on the new oil, Richard Franklin, managing director at TFS said: “Our new oil will enable companies to operate their systems safely and efficiently at high temperatures long-term, reducing the frequency with which oil needs to be reconditioned or replaced to ensure that parameters such as minimum flash points are maintained.”

European ATEX (Atmosphère Explosible) legislation – implemented in the UK via DSEAR (Dangerous Substances and Explosive Atmospheres Regulations) – stipulates requirements for the protection of workers against fires and explosions arising from the presence of hazardous substances in the workplace.
DSEAR demands that the risks inherent in the use of flammable fluids are assessed and eliminated or reduced. Regular fluid sampling and analysis is required to ensure that flash points do not fall below minimum acceptable levels. If necessary, oil must be replaced or conditioned so that a safe flash point is restored.
One of the main elements of TFS’ work is the reconditioning of customers’ thermal oil in order to maintain appropriate flash points.  The company was the first to offer this service, which is a quick, cost-effective, environmentally sustainable alternative to total fluid replacement: HTfluidfit extends fluid life by a factor of at least 10, saving customers up to 70% of their thermal fluid costs.
