Why Kilfrost
Technical support
As an established chemical manufacturer with extensive laboratory facilities, we provide comprehensive health checks for our speciality heat transfer fluids (HTF), deicing and anti-icing fluids.
Understanding and optimising your heat transfer fluids, deicing and anti-icing fluids
Our Technical Service Team is here to help with expert advice on the best solutions for your needs, along with guidance on how to maximise their performance and implementation. Below are the specific services we offer as part of our outstanding after-sales support.
Looking after your heat transfer fluids
After commissioning, we recommend that installed heat transfer fluids are checked at least once every six months. A basic check should include a visual inspection to identify any colour degradation, then testing the refractive index – which looks for product concentration and checks the pH level – we recommend this should be between 7-9.
We supply Thermal Fluid Test Kits to monitor the health of all Kilfrost heat transfer fluids as part of a routine maintenance schedule.
For further information on system monitoring and product support, please contact us.
Aviation fluid testing
At our Northumberland-based facility we have a fully equipped, controlled laboratory where customers can send samples to comply with SAE pre/mid-season sample analysis requirements and to ensure the fluid is fit for use.
ADF laboratory testing timetable
Pre-season (September – November)
- Storage facilities
- Vehicle tanks
- Vehicle nozzles
Mid-season Check (January – March)
- Vehicle nozzles
Further testing and investigations can be carried out by Kilfrost, should additional support be required.
ADF field testing
In addition to prescribed pre- and mid-season laboratory testing, aircraft deicing service providers are required to conduct specific field testing to ensure the fluids remain suitable for use.
We provide advice and support on the use of and interpretation of results from refractive index testing, visual checks and field viscosity measurements. Please note, the operational limits for the fluids are available on the product technical data sheets or by request.
Please get in touch with a member of our team to learn more.

Follow our sampling checklist
Incorrect sampling procedures can lead to incorrect decisions being made, based on the results of non-representative samples. Therefore, it is important to take samples that are fully representative of the bulk fluid. Aviation fluid samples should reflect what is being applied to the aircraft (and collected in a manner that simulates application) and should represent the bulk of the fluid.
