Phi-TEC I: A Bench-Top Adiabatic Calorimeter

The Phi-TEC I is an adiabatic calorimeter that enables the characterization of thermal runaway hazards during process development and scale-up.  The Phi-TEC I replicates industrial (large volume) conditions on a lab-scale, enabling thermal runaway hazards to be characterized safely and efficiently.

Via direct sample temperature measurement and by rapidly responding to any thermal changes, the Phi-TEC I accurately tracks exothermic events and maintains adiabatic conditions.  This adiabatic screening enables thermal events to be defined with the accurate characterization of the onset temperature (Td) and facilitates the calculation of other key parameters, such as the rate of pressure change, the adiabatic temperature rise (∆Tad,d), and the time to maximum rate (TMRd).
