    • Understanding Heat Transfer Fluid Degradation

      Heat transfer fluid (HTF) systems use HTFs as a heat carrier that circulates through a closed system that starts with a heater and ends with an object being heated. The process of heat transfer refers to the transfer of heat from a higher temperature object to a relatively lower temperature object. This process is maintained until the object being heated reaches thermal stability, and is vital in the... continue reading
    • Three tips for heat transfer systems

      The Oxford Electric Bell has been ringing constantly for over 175 years – so much so, that the apparatus has been dubbed the world’s most durable battery. But after all this time, it is still a scientific mystery how the bell has functioned for so long. For operators of thermal fluid systems, keeping operations running doesn’t have to be a mystery.   Here, Clive Jones, managing director of... continue reading
    • Eight ways to extend a plant’s operating life

      In a previous blog it was assumed that the operation life of a plant can be extended to 25 years. Dr Chris I Wright examines proven technologies to maximise a plant’s operating life. It is a fact that a plant’s life can be shortened by the thermal degradation of a heat transfer fluids (HTF), which includes a wide range of mineral (e.g. Globatherm M) and synthetic-based fluids (Globaltherm Omnitech).... continue reading
    • Protect pumps by using high purity heat transfer fluids

      There are essentially three critical product features of a well-designed high temperature heat transfer fluid – high thermal stability, high heat transfer efficiency and high purity. Global Heat Transfer examines why purity is so beneficial to a pump. A heat transfer fluid operating at high temperature for a long time will thermally degrade and the by-products of thermal degradation can potentially... continue reading
    • Maintaining highly efficient pumps

      Market research suggests the global heat transfer fluids market size was 465.9 kilo tons in 2014 and projects significant increases up to 2022. Global Heat Transfer examines how the sampling of a heat transfer fluid (HTF) may help to maintain an efficient pump and thermal plant. Many chemicals are used in the manufacture of HTFs and include silicone, aromatic, mineral and glycol. The speed that they are... continue reading
    • Trained engineers for a new system

      ~ The importance of knowledgeable staff when operating a heat transfer system ~ Thermal fluid based heat transfer is a specialist area, which means that new system engineers may have limited understanding of system operations. However, it is important for safety and compliance that engineers know when thermal fluid should be tested and analysed. Here, Clive Jones, managing director of thermal fluid... continue reading
