Automatic pressure tracking adiabatic acceleration calorimeter APTAC 264


APTAC 264 surpasses traditional designs by collecting temperature and pressure rise data more quickly, taking chemical reactivity testing to a new level.

The instrument can serve as:

  • High performance closed working chamber adiabatic calorimeter.
  • High temperature and high pressure reaction calorimeter
  • Open test chamber, capable of discharging and analyzing effluent. Research on emergency relief systems using the DIERS method of the American Chemical Engineering Society.

APTAC 264, with its high accuracy in testing results, can help factories scale up process design to the product level. This is achieved through:

  • Provide actual temperature and pressure data for dynamic modeling.
  • Verify the predicted chemical reactions and scenarios.
  • Verify the activity prediction of the emergency pressure relief system.
  • Directly measure the physical property data of complex mixtures.

APTAC 264 can be used for thermal analysis of various solids, liquids, gases/liquids, liquids/liquids, gases/solids, and liquid/solid mixtures. It can also be used for simulating intermittent or semi intermittent reactions, flame explosions, and emergency depressurization processes, as well as measuring some physical properties.

APTAC 264 has established a new standard for the accuracy of reactivity data measurement in the chemical manufacturing industry, including organic chemistry, petrochemicals, pharmaceuticals, agricultural fertilizers, fine chemicals, polymers and plastics, energetic materials, and other fields.
