TKS
History
The TKS in-flight de-icing system was developed during 1942 at the instigation of the UK Government, to meet the operational needs of allied aircraft flying during wintry conditions. TKS systems were initially used in Lancaster bombers and were subsequently fitted to a wide range of military aircraft.
The TKS company was formed by the co-operation of three companies, each with its own specialist technical expertise:
- Tecalemit (manufacturer of lubrication equipment)
- Kilfrost (manufacturer of specialist de-icing chemicals), and
- Sheepridge Stokes (manufacturer of porous metals using powder metallurgy)
The three companies formed a joint venture (TKS Aircraft De-Icing Limited) which became a wholly owned subsidiary of Kilfrost Limited, being co-located at its facilities in the North of England and London.
During the 1950's, porous panels were introduced to TKS systems, to enable greater efficiency in fluid distribution. The systems became more widespread, with approvals for such aircraft as the Lockheed Viking, Avro Shackleton and Avro York.
By the 1960's, TKS systems had further developed their scope beyond turboprop aircraft, and now could be found in light business jets such as the Hawker Siddeley 125. The system and fluids were updated in 1967 and continued until 1987 when TKS Aircraft De-Icing Limited was sold, to eventually become what is known today as CAV Aerospace Limited.
Kilfrost Limited has since continued its ground-breaking work in the field of de/anti-icing fluid technology in both general and commercial aviation, where it continues to be the global market leader today. TKS Systems are currently used in a wide variety of general aviation aircraft as the Hawker 850XP, a range of Cessna Caravans and the popular Cirrus SR22-G3.
Kilfrost is committed to fluid development and has produced both bespoke and generic 406B fluids for TKS systems. Ongoing product innovation includes a partnership with DuPont Tate & Lyle to produce the world's first TKS fluid derived from a sustainable source.
TKSsustain, has all the benefits of TKS 406B but with the added advantages of lower temperature functionality and improved aerodynamics. TKSsustain is in the process of FAA approval and will be available to selected customers by January 2009.
