Would you consider changing to a bio-sourced HTF?

Whilst heat transfer fluids (HTFs) might be one of the least expensive components of a system, they are critical to the way it functions.  But when you decide on a heat transfer fluid for your system, the environmental credentials might not be the first thing you consider.


HTFs perform the function of transferring thermal energy from one location to another for both heating and cooling applications. The market currently offers a number of different types of heat transfer fluids. These include:


  • Mono propylene glycol (MPG)
  • Mono ethylene glycol (MEG)
  • Potassium acetate and formate
  • Bio-sourced e.g. 1,3-propanediol or betaine

MPGs and MEGs are the most commonly used heat transfer fluids today. They are produced from fossil fuel oils and whilst their pricing, until recently, has been more favourable when compared to greener equivalent products, this will change as availability reduces and the world becomes less reliant on these forms of fuel.


How much focus is there on the green credentials of a HTF?


Within the HVACR sector we are all aware of the environmental changes that we should be making. We have, quite rightly, focussed heavily on the demands of F-Gas legislation and continue to do so, seeing many more companies choosing to use refrigerants with lower GWP (Global Warming Potential) values, focussing more on energy efficiency, as well as ensuring leak detection equipment, cleaning and maintenance processes are in place.


Considering the transition we are currently making to very low GWP refrigerants, the use of an eco-friendly heat transfer fluid creates the ultimate eco-efficient combination.


Greener HTF Products: Greenway® Neo N


Greener HTF's are already available and have been proven to offer performance and environmental benefits over the fossil fuel derived products.


These greener alternatives have shown to offer improved thermal stability and energy efficiency compared to fossil product derived heat transfer fluids, and have desirable biodegradable attributes.

The Greenway® heat transfer fluid range has been used throughout the UK and across Europe for over ten years with many case studies supporting product quality. Greenway® Neo N recently achieved NSF HT1 registration.
