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 patentedVariPhi™ option enables for all Accelerating Rate Calorimeter / Automatic Pressure Tracking Adiabatic Calorimeter systems (ARC®/APTAC®) DSC like performance in the scanning mode: exotherms, endotherms and heat capacity plus pressure data.
The Accelerating Rate Calorimeter 244 (ARC® 244), formerly known as TIAX ARC 3000, is designed to safely measure the amount and rate of heat release associated with the processing or storage of chemicals.
This information is vital in developing and evaluating processes to ensure safe operation and to prevent thermal runaway which can have devastating effects.
The Accelerating Rate Calorimeter 244 (ARC® 244) technology is integral to designing inherently safer batteries as well as measuring energetic materials used in such products as explosives, propellants, and air bags.
Major Features and Benefits
The Accelerating Rate Calorimeter 254 (ARC® 254) provides adiabatic calorimetry data in a safe, controlled laboratory environment. This information helps provide a sound understanding of the fundamental physical processes involved. From this understanding, various safe operating systems and procedures can be developed to mitigate the hazards posed by a reactive system.
The Accelerating Rate Calorimeter 254 (ARC® 254) simultaneously measures temperature and pressure. The sealed pressure system also allows the user to evaluate the effect of different gas atmospheres on the thermal stability of the system.
Gaseous reaction products may be analyzed at the end of an experiment to help identify and understand the reaction mechanisms involved.
The Accelerating Rate Calorimeter 254 (ARC® 254) is designed to model the course of a large-scale reaction on a small scale. A test material is externally heated in a fixed volume until exothermic activity is detected. Keeping that sample in an adiabatic environment where no energy is lost, the calorimeter then measures and records the sample temperature and pressure.
A single experiment provides data for use in the following:
User safety is a key objective in the design of model 254. The user is protected by a series of safety systems that are completely independent of the control system. These safety systems work to protect the user in the event that the primary control system fails. Fully computer-controlled and highly automated, the Accelerating Rate Calorimeter (ARC® 254) features a graphical interface that is easy to learn and use.
The system is totally integrated into clean, modern designs in which all routinely used equipment is easily accessible.
APTAC® 264 takes the testing of chemical reactivity a step forward by enabling the user to acquire much faster temperature and pressure rise data than did the earlier designs.
The instrument can function as:
The precision and accuracy of APTAC® 264 test results help companies in scaling up process designs to production scale by:
APTAC® 264 can be used for the thermal analysis of solid or liquid chemicals or for gas/liquid, liquid/liquid, gas/solid, and liquid/solid mixtures. It can also be used for process simulation of batch and semi-batch reactions, fire exposures, emergency relief venting, and physical properties measurement.
It offers a new degree of accuracy in reactivity data for chemical manufacturing industries, including organic chemicals, petrochemicals, pharmaceuticals, agrochemicals, fine organics, polymers and plastics, and explosive highenergy materials.
The new instrument is designed to test the performance and safety of energy storage devices such as large format lithium ion batteries used extensively in electric vehicles and airplanes, as well as stationary power back-up and storage applications. The instrumentation is able to safely and accurately characterize heat output and efficiency of the batteries in varying temperature, pressure, load and use conditions, providing precise and critical information previously unavailable. Temperature has a strong impact on performance, safety, and life of batteries. Temperature control is necessary to successfully operate lithium ion batteries, particularly for electric drive vehicles.
The IBC's innovations are complete thermal isolation (patented), the ability to test large cells and batteries, and the features needed to test high energetic batteries safely, providing a level of accuracy and functionality not seen in other calorimeters. Precisely measuring heat generation helps to cost-effectively optimize battery thermal-management systems, extend battery life and improve safety.
