Consumer Safety The Greenway® Neo N formula is NSF HT1 registered The formulation of the range of Greenway Neo® heat transfer fluids, acclaimed by the market since 2010, has changed. Greenway® Neo is now NSF HT1 registered for accidental food contact and is now called Greenway® Neo N. It maintains the same heat transfer eciency as the previous formula and, in particular, meets all requirements for food processing applications. This new formula will be available in 2021. In addition, Greenway® Neo N has a viscosity less than that of conventional heat transfer fluids (with MPG base) and can reach temperatures as low as -50 °C which is not possible with a MPG. In certain cases, it is possible to reduce the size of piping and pumps thus leading to a reduction in energy consumption. Focus on food applications Heat transfer fluids are frequently used to lower temperatures in storage areas, manufacturing processes and the processing of food and drink. For consumer safety, it is necessary to select a non-toxic heat transfer fluid. It should be noted that there is no such thing as a “food grade” heat transfer fluid, or even one of “food-grade quality”. A heat transfer fluid is not a food-grade ingredient. There are however heat transfer fluids registered by the National Sanitation Foundation (NSF) for accidental contact with foods. NB : in the event of contact with a heat transfer fluid, the contaminated food product must not be placed on the market. NSF HT1 registration does not imply that the contaminated food product can be consumed. Further details on sanitary hot water applications Climalife oers a range of heat transfer fluids for applications that may be in contact with sanitary hot water (SHW, i.e. heated water used for domestic purposes routed via pipes to the points of use (shower, washbasin, dishwasher, etc.). There are several techniques for heating SHW, such as heat exchange with a loop of water (from a solar source for example) which is hotter than the water to be heated. In order to limit risks associated with accidental ingestion in the event of leaks to the SHW, Climalife has added a bittering agent to the Greenway® Neo Heat Pump N and Greenway® Neo Solar N. The formulation bases of Climalife heat transfer fluids • Bio-sourced 1,3-prpanediol • Mono propylene glycol (MPG) • Mono ethylene glycol (MEG) • Potassium acetate and formate • Betaine Did you know ? With formulae based on renewable plant based raw materials, the Greenway® Neo N product range provides environmental consistency. Plus, the life cycle analysis* shows that its production oers significant environmental advantages: less greenhouse gas emissions (-56%) and less non-renewable energy (-38%) used in production compared with conventional heat transfer fluids based on fossil fuels (petroleum) such as the MPGs. *The Life Cycle Analysis is an analysis which takes into consideration the environmental impact of the product from cradle to grave. Bio-sourced 1,3 propanediol : raw material of the Greenway® Neo N range Greenway Neo N is a heat transfer fluid based on bio-sourced 1,3 propanediol, Susterra® approved by NSF International (Proprietary Substances and Nonfood Compounds) is a component suitable for use in heat transfer fluids in the event of accidental contact with foodstus (Category code: HTX-1; NSF approval number: 141749) to be used in the immediate vicinity and within foodstu conversion areas in compliance with good manufacturing practice. Moreover, it is recognised as safe by the Food and Drug Administration (FDA) in the US in section 21CFR184.1666 and meets the specifications of the Food Chemicals Codex, 6th edition (2008). 1,3 propanediol is classified as E1520 in an amendment to directive 95/2/CE of the European Union, which regulates human foodstu additives, and is listed in appendix I of regulation (UE) no.10/2011 of the Commission as a monomer and additive authorised for materials and objects in plastic intended to come into contact with foodstus.
