DESCRIPTION
The patented* VELCON SWIFTKit is the first practical device to
determine the Interfacial Tension (IFT) of aviation jet fuel
in the field. The IFT value is a general indication of the
surfactant (surface active agent) level in fuel; higher IFT
values indicate lower surfactant levels. Surfactants can
disarm coalescer elements, which could allow excess
water downstream and into the aircraft.

APPLICATIONS
The SWIFTKit can be used for general quality checks on
fuel during transfer and transportation, and particularly for
receipts into airport storage. The SWIFTKit is especially
useful to determine the condition of clay treatment
cartridges by comparing the upstream and downstream
IFT values. An increase in IFT value shows that the clay
is still effectively doing its job of removing surfactants.
