Key Advantages
ENHANCED BUILT-IN SAFETY
Creating a Safe Environment in the Lab
•Vapor containment system: decreases operator exposure to jet fuel
vapor
•Safety door: prevents exposure to the hot heater tube section; test
won’t start until the door is closed
•Reduced exposure to fuel: fuel is flushed at the end of the test; keeps
test section dry during disassembly
9. 9
Key Advantages
SIMPLEFIED OPERATION
High levels of automation and hardware
advancements
•Automates traditionally time-intensive manual activities: such as pump
priming, flow monitoring, and sample aeration
•Enhanced user functionalities: quick-connect dryer canister, tool-less
fasteners, and automatic line flushing to minimize fuel exposure
•New fully integrated RFID reader: easy and fast data extraction
•Built-in IHT writer: seamless integration with the Alcor Intelligent Heater
Tubes™
•Multiple languages: instrument software supports many local language
requirements

Key Advantages
INCREASED LAB PRODUCTIVITY BY 25%
Reduced User Intervention
JFTOT IV with advanced technology improvements:
•Significantly faster analysis cycle time
•Reduces operator intervention by approximately 40 minutes
•Allows the operator to focus on higher value responsibilities.
•Provides traceable results with the Intelligent Heater Tube (IHT) by
storing the analysis data electronically on the IHT, rather than on having a
hard copy print out of the test

Use Alcor JFTOT®
IV and Alcor Intelligent Heater Tubes
The JFTOT® Jet Fuel Thermal Oxidation Tester is a fully integrated bench-top instrument that, along with a visual or video tube rater, provides everything needed to safely study the thermal oxidation of any typical petroleum-based liquid fuel. The instrument is normally used in a batch mode where a fuel sample is held in a reservoir and pumped across a heated metal surface to a second reservoir. The purpose of the JFTOT® system is to facilitate the formation of deposits from jet fuel heated in the presence of dissolved oxygen and a metal surface. The deposits are then compared against a standard to determine the degree of fuel degradation due to thermal oxidation. The JFTOT® has been significantly improved to allow simplified setup and user-friendly operation through a touch-screen and menu-driven embedded computer.
The JFTOT IV is the sixth instrument in a long line of jet fuel thermal oxidation testers. For over 40 years, the Alcor JFTOT has kept up with industry demands for reliability, safety and innovation. The JFTO VI IV addresses the industry’s requirement for improved safety, simplified operation ad increased productivity.
Although you will find significant design innovations in the JFTOT IV, the most important part of the system, the heater tube section is the same as previous version. The JFTOT IV passed the ASTM equivalency process with flying colors; the JFTOT IV was found to be equivalent to the previous JFTOT models thus assuring the user that results you obtain will be consistent and reliable.
The JFTOT IV is now listed in Table 1 of ASTM D3241, revision 13 and will soon be in the approved instrument registration table in IP323. These standard methods are referenced in several reference methods, some of which are listed here. The most used reference standards, D1655, D7566 and DEFSTAN 91-91 by default reference the most current version of the methods D3241 and IP323, so the JFTOT IV is approved for use to test jet fuel in all countries that abide by these reference standards.
There are many innovative features to the new JFTOT IV. These innovations can be grouped into three main categories: enhanced safety, simplified operation and increased lab productivity.
The JFTOT IV vapor containment system decreases operator and environment exposure to jet fuel vapors. Also, the sample and waste jars pivotal to this vapor containment system have quick connect and quick releases for easier handling. The safety door prevents exposure to the hot heater tube section. It also protects the heater tube section from temperature fluctuations in the lab, improving temperature stability and consistency between tests. At the end of the test, the fuel is flushed out of the test section and internal tubing with pressurized air from the internal air pump. This keeps the test section dry during disassembly.
