Overview

Revolutionary Advancement in Safety and Automation of Diesel Thermal Oxidation Testing

The new Diesel Thermal Oxidation Tester - DTOT is a fully integrated bench-top instrument that provides everything needed to safely study the thermal oxidation of diesel or biodiesel. 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. 

New DTOT which is suitable for several blends of diesel fuel like Pure Diesel (B0), Diesel Fuel with 7% FAME (B7) and Diesel Fuel with 20% FAME (B20).

Key advantages:

  • Design achievements contribute to a significantly faster analysis cycle time
  • Provides traceable results by storing the results electronically on the IHT, rather than only having a hard copy print out of the test
  • Automated traditionally time-intensive manual activities, such as pump priming, flow monitoring, and sample aeration
  • Easy and fast data extraction with a fully integrated RFID reader/writer for the Intelligent Heater Tubes™ (IHT)
  • Instrument software supports multiple languages
  • Decreased operator exposure to diesel vapor with a vapor containment system
  • Prevents exposure to the hot heater tube section with a safety door; test won’t start untill the door is closed
  • Reduced exposure to diesel /biodiesel by flushing it at the end of the test; keeps test section dry during disassembly
