Accelerating Rate Calorimeter
The Enhanced System Accelerating Rate Calorimeter
The world's best selling and benchmark adiabatic calorimeter. Giving full adiabatic runaway information for both temperature and pressure events.
Devised by Dow Chemical Company in the 1970's, an explosion at a Dow UK site led to commercialisation of ARC technology. The Chemical Processing Industry has been safer from its first availability in 1980! The ARC has specific features and advantages that make it unique and preferable to all other technologies that were available at this time - and today 30 years later this technology is still the number one choice for most people focusing in the area of quantifying exothermic reactions, effect of heat upon materials and simulating runaway reactions.
THT has played the major role in ARC technology development and has continuously kept ARC technology in manufacture. THT has produced up-to-date instruments and has extended and enhanced the technology as requested, by users. THT has worked with users worldwide to understand their needs and to develop new products and applications.

Low Φ containers
Designed by THT these low Φ containers are designed to enable accelerating rate calorimeter users to bridge the gap into the world of low-phi testing. These cells are available with several different fittings and can also be fitted with magnetic stir bars. Currently these containers are offered in stainless steel although other materials can be produced. Contact us for further details.
Burst disk unit
THT has designed this burst disk assembly, which is suitable for any accelerating rate calorimeter. Designed to sit above the calorimeter, this device enables the user to protect the system from cell ruptures. The user can fit a number of special burst disks which are designed to rupture at specific pressures and will cause the cell to rapidly discharge. Any liquid vented will be contained within the catch pot. This system is ideally used alongside low-phi containers and glass bombs
Battery sample holders
THT manufactures holders for specific batteries to enable testing in both open and closed (with pressure connections) modes. THT are able to manufacture special holders for any battery dependent on a specified minimum order. Please contact us with your specific requirements.

The ARC with specialised options is available for sample testing.
THT offer a commercial service for clients with minimal testing requirements and cannot justify an instrument purchase.
Hallmarks of this service are
- Cost effective
- Expert analysis
The service can range over all of THT's calorimeters and include DSC and purpose constructed test facilities.
Components of batteries and small batteries can be tested using the ARC. For larger cells the EV-ARC can be used.
