The following plot shows the resulting transient temperature changes in a reactor equipped to perform power compensated calorimetry. The 4547 jacketed reactor used here has an internal volume of 1.2 L and was half full of water. Data were recorded at one minute intervals while the set point bias was toggled 1.5 C. The y-axis is the trim heater power (watts).

The system’s reaction vessel, equipped with a circulating jacket, is isothermally controlled, ensuring precise temperature regulation. The compensation or trim heater, which automatically varies its electrical power, maintains the desired process temperature as the process heat load changes.

This feature allows the calorimeter to attain thermal equilibrium more quickly than other calorimeters, making it advantageous for measuring heat flow from short-lived reactions.

Furthermore, the Power Compensation Reaction Calorimeter provides cooling power estimation, essential for maintaining safe and effective process conditions. The integration of the Parr 4871 Process Controller ensures seamless control and coordination of the system.

Whether it’s a chemical research laboratory exploring new compounds, a pharmaceutical company developing new drugs, or an academic institution teaching the principles of calorimetry, the Power Compensation Reaction Calorimeter offers a robust and user-friendly solution. Its high performance, precision, and innovative features make it an invaluable asset for anyone involved in chemical reaction monitoring.
