Time to check your Heat Transfer Fluids

Original post 10/12/18. Edited 10/12/20.


Ice crystalAs we head into the winter months, now is a good time to review the performance of the Heat Transfer Fluid (or HTFs) in your heating or cooling systems.

HTFs are used in refrigeration, air conditioning, central heating, heat pump, solar thermal and underfloor heating applications. Being one of the least expensive components of a system, they are however critical to the way it functions and how effectively it transfers warmth from one location to another and provide protection from freezing and corrosion.

When poor quality HTFs age, they can degrade meaning they can become less effective at freeze protection. The inhibitor package may become compromised leading to common problems such as the start of corrison, the formation of sludge and a change in viscosity, each of which can reduce the efficiency of systems. Therefore the need for regular maintenance and servicing is essential. It's always worth using a good quality HTF and one that contains corrosion inhibitors which can limit corrosion in water systems.


The main benefits of heat transfer fluids are:

  • The frost protection of central heating and solar heating networks.
  • The efficient transfer of cold production in the case of chilled water air conditioning systems and process cooling.

We would like to emphasise the fact that high quality heat transfer fluids contain corrosion inhibitors and therefore limit corrosion in water systems.
Don’t get caught out this winter when the ambient temperature drops below freezing.  Make sure now that the strength of the fluid in your systems is at the correct level to ensure continued operation throughout the winter months.
