For the maintenance and safety of thermal fluids

HTfluidfit is a revolutionary, proactive service for the maintenance and safety of thermal fluids; it offers a real alternative to the costly and time-consuming process of fluid disposal and re-filling of systems. Using state-of-the-art fluid conditioning rigs, vital fluid parameters such as flashpoint, are maintained at their optimum condition with the potential to extend fluid life by a factor of 10 or more!

HTfluidfit offers:

  • Reduced risk and improved safety
  • Guaranteed flash and fire points
  • No system downtime
  • Extended fluid life
  • Reduced waste
  • Consistent heat transfer performance
  • Consistent viscosity and vapour pressure
  • Reduced carbon footprint 

Many process industries use thermal oil to transfer heat around the process plant. However, these oils degrade over time due to factors such as high temperatures, high film temperatures and oxidation causing loss of thermal efficiency, increased flammability, cavitation, mechanical failure, system downtime and associated cost. More importantly, when combined with other system conditions, plant safety can be drastically compromised – and it is now a legal requirement to maintain minimum flashpoints.

For many companies the traditional solution to the degradation problem is to periodically replace thermal oil. The sampling and analysis of the fluid is a requirement within the Dangerous Substances and Explosive Atmospheres Regulations (DSEAR is the UK implementation of the EU ATEX Directive) and the fluid must be conditioned or changed when the fluid falls out of specification. Similar regulations apply in other EU countries. Unfortunately, this reactive process requires the expense of replacing huge amounts of oil resulting in long periods of downtime whilst the system is drained and then re-filled.

HTfluidfit is a revolutionary, proactive service for the maintenance and safety of thermal fluids. Using state-of-the-art fluid conditioning rigs, fluids are maintained at their optimum condition with the potential to extend fluid life by a factor of 10 or more! Processes remain up and running and the expense of purchasing new oil is avoided. The rigs work by reconditioning the existing oil via the systematic inline removal of volatile organic compounds (VOCs), returning the oil to a safe condition. Based on the innovative ‘flash evaporation’ technology developed with patented technology from many years of engineering, the rigs are an ideal way to keep your process safe and cost-effective.
