FAI has been the industry leader in adiabatic calorimetry since the concept of DIERS testing was first introduced in 1985. Safe process design requires knowledge of chemical reaction rates, character and energy release - all of which can be obtained from a low phi factor adiabatic calorimeter such as the VSP2 or ARSST. The VSP2 (Vent Sizing Package 2) and the ARSST (the Advanced Reactive System Screening Tool) can be used for both closed and open test
experiments. A closed test configuration allows the measurement of
continuous pressure-temperature data during chemical runaway. |

A typical VSP2 test uses an 80 ml sample in a 120 ml test cell. Test cells
can be stainless steel (304 or 316), hastelloy C, titanium, and
glass-lined.
Various vent dimensions can be chosen for open test cells.
Customized test cells are available. Please inquire for more
information. The VSP2 offers a variety of process simulation options
including:

An open system ARSST test is particularly well suited
for characterizing gassy systems. Low phi-factor glass test cells are avilable in 5 ml, 10 ml and 20 ml sizes.
The Super Magnetic Stirrer ensures that even viscous or immiscible liquids and slurries are well-mixed throughout an experiment, even at high temperatures and pressures. Mechanical stirring is also available for the VSP2. |
