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 ExothermicA sample transition or a reaction is exothermic if heat is generated.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 (Accelerating Rate Calorimetry (ARC)The method describing isothermal and adiabatic test procedures used to detect thermally exothermic decomposition reactions.ARC®®) DSC like performance in the scanning mode: exotherms, endotherms and heat capacity plus pressure data.

Instrument / ModeAdiabaticAdiabatic describes a system or measurement mode without any heat exchange with the surroundings. This mode can be realized using a calorimeter device according to the method of accelerating rate calorimetry (ARC®). The main purpose of such a device is to study scenarios and thermal runaway reactions. A short description of the adiabatic mode is “no heat in – no heat out”.Adiabatic
