Time Flies - The Kilfrost Story
To celebrate our 90th anniversary, we created the below video to document the incredible Kilfrost Story. Watch Time Flies to learn more about the innovative history of our family-owned company.
Leading the way to a more sustainable future
Since our inception, we have been at the forefront of pioneering fluids that enhance safety and performance, and environmental sustainability is integral to our product development.
Our manufacturing capabilities are backed by the knowledge and expertise of our scientists and engineers, and Kilfrost’s ongoing investment in research and development facilities.
Why choose Kilfrost for heat transfer fluids and deicing/anti-icing solutions?
As a family business, based in Northumberland, UK, we’re proud of our heritage and the difference we have made to the world. We continue to make that difference through insight, ingenuity and innovation in chemical manufacturing.
Pioneers
More than 90 years ago, Joseph Halbert, inspired by the humble snowdrop and with a passion for football, invented a world-first deicing fluid: initially, this was used to deice football pitches, before it was applied to aircraft… and had a world-changing impact.
Performance driven
Applying our understanding of rheology, we have developed a range of fluids that outperform MEG and MPG by maintaining viscosity, even at lower temperatures.
Environmentally conscious
Through intense research and development, we’ve been able to develop a range of fluids that are less toxic and corrosive than the alternatives. This helps to protect both the environment and the equipment that the fluids are used in.

Data Centres
Kilfrost’s heat transfer fluids provide the precision and performance needed for closed-loop liquid cooling systems in data centres.
