TKS de-icing fluid for aviation


Aero-Sense is one of the leading European producers and providers of TKS fluid for in-flight de-icing. Each batch is carefully analyzed so that viscosity, freezing point, pH value and many other parameters are respected. Before packaging, the fluid is filtered down to 0,5 micron to prevent debris blocking the laser drilled titanium leading edges.
