Калориметрия - Phitec 2

The PHI-TEC system is a computer controlled adiabatic calorimeter designed to simulate the thermal behaviour of larger scale chemical reactors, especially when studying uncontrolled and run-away reactions.

The PHI-TEC is available in two different models, the entry level PHI-TEC I uses high pressure cells, or bombs, of approximately 8ml volume to determine the heat evolved and pressure developed during the reaction. It features a high precision and rugged solid copper adiabatic furnace and a stainless steel containment vessel. Control is by the latest in-house developed Windows software.

PHI-TEC II incorporates the same furnace and containment vessel, however it also includes a pressure tracking facility, which allows for the use of low phi-factor test cells. These cells are of ~ 100ml volume, but are very thin walled and have very low thermal inertia (a low phi-factor). This allows the PHI-TEC II to simulate the behaviour of a full-scale plant during "worst case" scenarios and to provide information for calculations such as vent sizing and flow restrictors.

A complete system includes dedicated software for control and data analysis. Sample temperatures can be tracked at up to 200°C/min, up to 500°C maximum and up to a pressure of 138 bar pressure. A wide range of test cells enable the precise simulation of plant conditions, including overhead agitation and specialist materials of construction.
