Accelerating Rate Calorimeter

The Enhanced System Accelerating Rate Calorimeter

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.
