The Falex Thermal Fouling Tester (FT2) is the first instrument designed specifically for the SAE ARP 5996 Evaluation of Coking Propensity of Aviation Lubricants Using the Single Phase Flow Technique.

The FT2 is the ultimate in ease of operation and provides user flexible programmability with extensive customizable safety and shutdown protocols. The FT2’s enhanced hotspot determination and profile automation routines assure the highest precision for your critical turbine oil analysis laboratory.

A lubricant sample is passed over a pressurized, tube-in-shell heat exchanger for a set time period. The specimen tube, made of 316 stainless steel, is weighed before and after the test to determine the amount of coking propensity exhibited by the test lubricant.

»» An integrated Peltier cooling system saves valuable bench space and provides consistent cooling temperatures for each test

»» Automatic tube temperature profiles reduce operator time and improve test precision

»» A redundant safety system keeps the unit self-sufficient in case of leak, mishap or power outage

»» High-Speed data acquisition of all critical thermocouples and system outputs

»» Hermetically-sealed gear pump for leak-free longevity and pulse-dampened flow

»» Customizable test parameters for additional points of research
