Accelerating Rate Calorimetry

Accelerating Rate Calorimeters help industry operate safely and profitably. As highly versatile, miniature chemical reactors, they measure thermal and pressure properties of exothermic chemical reactions. The resulting information helps engineers and scientists identify potential hazards and address key elements of process safety design including emergency relief systems, effluent handling, process optimization, and thermal stability.

The patented VariPhi^® option enables for all Accelerating Rate Calorimeter systems (ARC^®) DSC like performance in the scanning mode: exotherms, endotherms and heat capacity plus pressure data.

Accelerating Rate Calorimeter 254 (ARC^®)

This new Accelerating Rate Calorimeter (model ARC^® 254), formerly known as TIAX New ARC 5000, is a specialized instrument to help industry operate safely and profitably. Highly versatile, miniature chemical reactor, it measures the thermal and pressure properties of exothermic chemical reactions. The resulting information helps engineers and scientists identify potential hazards and tackle key elements of process optimization and thermal stability.

Accelerating Rate Calorimeter 244 (ARC^®)

The cost-effective Accelerating Rate Calorimeter 244 (ARC^® 244) is designed to safely measure the amount and rate of heat release associated with the processing or storage of chemicals with a sample volume of 0.5 ml to 7 ml. The key features are high performance, safety, usability, and flexibility with data integrity and robustness in a temperature range from ambient to 500°C.
