Three steps to heat transfer fluid regulatory compliance

According to statistics from The Home Office, Fire and Rescue services in the UK attended 14,308 fires in non-dwelling buildings in 2020. The effects of fires in the workplace can be devastating, causing injury as well as significant damage to property and the surrounding environment. However, most fires are preventable when employers implement the correct preventative measures. Here Clive Jones, managing director of thermal fluid specialist Global Heat Transfer, outlines the three key steps to managing thermal fluids in accordance with regulations. Any facility that uses heat transfer systems containing thermal fluid must proactively maintain them to mitigate for potential…

The importance of proactive boiler maintenance

Thermal fluid systems are commonly made up of three key components — a thermal fluid boiler or heater, an expansion tank and thermal fluid circulating pumps. If all these components are well maintained, a thermal fluid system can last for several decades. However, because a boiler operates silently in the background of the facility, engineers often overlook it. Here Clive Jones, managing director of thermal fluid supplier, Global Heat Transfer, explains the importance of proactive boiler maintenance and offers advice on best practice. Traditionally, industrial boilers operated for around 15 years before they needed replacing. After years of development andresearch…

Top tips for flash point management

There are many treatments for migraines, from cold compresses and over-the-counter medicine, to Botox. However, if you don’t deal with the cause of the migraine, for example stress or dehydration, it will keep coming back. Similarly, when operating a heat transfer system, the key to maintenance is dealing with the problem, not the symptoms. Here Clive Jones, managing director at thermal oil supplier Global Heat Transfer, gives his advice on effective flash point management. When an issue arises in a heat transfer system, it should be solved as quickly as possible so that it does not negatively impact safety or…

No time for compromise

The current Coronavirus outbreak has led to increased pressure on the food industry. For example, a penchant for lockdown baking means that grocery sales of flour increased in the UK by 92 per cent. This causes smaller mills, such as one in Oxfordshire, to begin running at 24-hour operations for the first time in its 125-year history. When under pressure to upscale production, manufacturers cannot forget the importance of good practice, particularly in highly regulated industries. Here Clive Jones, managing director of thermal fluid specialist Global Heat Transfer, explores the importance of maintenance in these times.   Food, beverage and…

Deadly degrees of difference

Temperature plays a crucial role in everyday life. One small change could impact something simple such as a morning coffee or larger aspects such as seasons and personal health. In manufacturing, temperature can mean the difference between productivity and costly mistakes, particularly when working with thermal oil. Here, Clive Jones managing director of Global Heat Transfer, explains how temperature can impact the performance and life span of a heat transfer fluid.   In June 2019, Müller UK recalled two Cadbury desserts from supermarkets after discovering the possible presence of listeria monocytogenes. To kill off listeriosis in food, manufacturers must ensure…

Thermal fluids in the public sector

In early 2019, two outbreaks of scabies in correctional facilities hit the international news, one at the Women’s Huron Valley Correctional Facility, Michigan, the other at Polmont Young Offenders Institution near Falkirk, UK. Highly contagious diseases such as scabies can more easily spread in facilities where hundreds of people, often in vulnerable health conditions, share the same spaces, such as in hospitals and prisons. One way to help prevent the spread of infection is to wash laundry frequently and at high temperatures. Here Clive Jones, managing director of thermal fluid specialist Global Heat Transfer, discusses best practice for maintaining efficient…

High temperature heat transfer fluids degrade when used at high temperature for prolonged periods, so what can be done to slow this process?

Heat transfer fluids (HTFs) can be used at very high temperatures (around 400 degrees Celsius is the standard in concentrated solar power plants). With prolonged use these fluids will start to degrade and the by-products that form need to be actively managed to help maintain a safe operating environment and to simply extend the fluid’s operating life. Indeed, few companies understand that regularly servicing a HTF and HTF systems can help sustain their longevity.  Global Heat Transfer examines how the build-up of short-chain hydrocarbons, a by-product of HTF thermal degradation, can be managed. Ennis [1] described the process of thermal…

Drawing Heat Transfer Samples and Personal Protective Equipment

The use of standardised test methods enables thermal decomposition products of a Heat Transfer Fluid (HTF) to be quantified accurately. For test results to be meaningful (ie predictive), however, it is important to gain a representative HTF sample, which is done whilst the HTF is hot and circulating in the heat transfer system. It is good practice to take representative HTF samples on a regular basis (as frequently as is feasibly possible) and to monitor the decomposition of a HTF over time to reduce the potential of finding false negative or false positive results (read more about this in a previous…
