TREATMENTS AND FLUIDS
products, these fluids are produced from crops such as corn, sugar beet and soybeans. Many have been shown to offer improved thermal stability and energy efficiency compared to oil based or natural gas derived heat transfer fluids, and additionally have desirable biodegradable attributes.
Heat Transfer Fluids with greener credentials are available from many stockists around the UK. An example of this is Climalife’s plant-based Greenway Neo N product, which is based on a sustainable bio-sourced 1,3 propanediol solution from plant origin. Life cycle analysis undertaken by DuPont Tate & Lyle BioProducts, has looked at this product’s environmental impact from cradle to grave, showing that it offers environmental advantages such as 56% less greenhouse gas emissions and 38% less non-renewable energy when used in production and compared to conventional heat transfer fluids based on fossil fuels such as MPGs. The product which has recently achieved NSF HT1 registration too, has been used throughout the UK and across Europe for over ten years with many case studies supporting the product quality.
NSF HT1 certification means that the product is suitable for accidental food contact within the food industry. All ingredients in the formula are FDA certified. The FDA is the Food and Drug Administration, a federal agency of the United States Department of Health and Human Services.
Case studies using greener HTFs Food Production – The ecological footprint of an installation can be reduced by choosing a heat transfer fluid with low viscosity which mini- mises energy consumption. In a case study that Climalife carried out with Blédina, part of the Danone Group, at a food production site, energy savings in the form of a 30% reduction in pressure loss was seen due to the low viscosity of the Greenway® product. Project Manager on site, Nicolas Tomaz said "We chose Greenway® Neo for its performance as a heat transfer fluid. Due to Greenway®’s low viscosity, the site opted for smaller KSB pumps, thereby enabling

significant energy savings: a reduc- tion in pressure loss of almost 30%, which is impressive".
Solar Thermal – In another Climalife case study, a sports complex decided to install solar panels to generate heating and hot water for the facility. Using Climalife’s Greenway® Neo So- lar for all its collective solar facilities it found that it was able to hold the high temperatures obtained during the summer periods and prevent the accelerated degradation that occurs when a MPG is used. The Climalife product expands and deteriorates four times less at 150° C, allowing the customer to set up facilities with lower maintenance costs that were much more resistant to the high stresses they undergo. Alexandre Priquet from climate engineering firm Bourrié commented "The fluid is very stable, and we have not seen any failure to increase pressure in the network. In addition to its techni- cal characteristics, the fact that it is plant-based is also a plus for the whole system."
Renewable technologies with renew-
As public demand is changing and consumers move more and more towards renewable energies and greener expectations, it makes sense to increase the pace of this change. If a new heat pump or solar thermal panels are to be installed, wouldn’t the greener choice be to use a heat transfer fluid derived from a renewable source rather than a purely chemical product with potential harmful elements. With the greener products already available, and already proven, can we speed up this shift? It would be great to see demand increase for these greener alternatives. Pressure is building from the consumers together with pressure from the Government, as they talk of a Green Industrial Revolution and their 2050 net zero target, so why not be seen to take a greener step in your next HTF selection and proudly share your experiences with the market. There is lots of expertise from companies such as Climalife that can support you in making the change.
