Multiple Module Calorimeter MMC 274 Nexus^®

The Multiple Module Calorimeter (MMC)A multiple mode calorimeter device consisting of a base unit and exchangeable modules. One module is prepared for accelerating rate calorimetry (ARC), the ARC-Module. A second one is used for scanning tests (Scanning Module) and a third one is related to battery testing for coin cells (Coin Cell Module).MMC 274 Nexus^® can be used for a wide range of applications in different areas

Process Safety: The Accelerating Rate Calorimetry (ARC)The method describing isothermal and adiabatic test procedures used to detect thermally exothermic decomposition reactions.ARC^® Module

Heat-Wait-Search (HWS)Heat-Wait-Search is a measurement mode used in calorimeter devices according to accelerating rate calorimetry (ARC).Heat-Wait-Search and Pressure Tests
A defined volume of a sample (ml scale) is placed in a tube-shaped container. The container is surrounded by a sophisticated heating system. Depending on the operating mode, the surroundings of the tube vessel are controlled to the same temperature as the sample. If there is no temperature difference between the surrounding heaters and the sample, then all the heat generated by the sample stays inside the sample.

Key Features of the ARC^® Module

• Heat-Wait-Search (HWS)Heat-Wait-Search is a measurement mode used in calorimeter devices according to accelerating rate calorimetry (ARC).Heat-Wait-Search tests for Thermal runawayA thermal runaway is the situation where a chemical reactor is out of control with respect to temperature and/or pressure production caused by the chemical reaction itself. Simulation of a thermal runaway is usually carried out using a calorimeter device according to accelerated rate calorimetry (ARC).thermal runaway reactions
• Ramp mode for fast screening of unknown samples
• Pressure measurement

The Scanning ModuleA calorimeter module being part of the Multipe Module Calorimeter (MMC) allowing for scanning test of a sample. This procedure can serve as a screening test in order to detect a thermal hazard potential within a reasonably short measurement time.Scanning Module

IsothermalTests at controlled and constant temperature are called isothermal.Isothermal and Scanning Tests

Here, an additional heater is placed on the outside of the sample container. This allows for a defined power input and more accurate temperature control of the sample. The external heater is useful for running IsothermalTests at controlled and constant temperature are called isothermal.isothermal and constant temperature ramp tests, especially in those experiments where reaction energies are higher.
