Accelerating Rate Calorimetry 

I calorimetri adiabatici aiutano l’industria ad operare in modo sicuro e proficuo.

In quanto versatili reattori chimici in miniatura, misurano sia le proprietà termiche e che le pressioni delle reazioni chimiche esotermiche.
Le informazioni risultanti sono di supporto ad ingegneri e scienziati nell’identificazione di rischi potenziali ed elementi chiave nei i processi di sicurezza, tra cui i sistemi di prima emergenza, il trattamento degli scarti, l’ottimizzazione di processo e la stabilità termica.

L’opzione brevettata VariPhi®® consente nei Calorimetri Adiabatici di Reazione (ARC®®), prestazioni tipo DSC in modalità scansione: valutazione di processi esotermici, endotermici e calore specifico, unitamente ai dati di pressione.

Accelerating Rate Calorimeter 244 (ARC®)

The cost‐effective ARC® 244 is designed to safely measure the amount and rate of heat release associated with the processing or storage of chemicals within a container volume between 1.5 ml and 8.5 ml.

Accelerating Rate Calorimeter 254 (ARC®)

The Accelerating Rate Calorimeter 254 (ARC®) provides AdiabaticoAdiabatic describes a system or measurement mode without any heat exchange with the surroundings. This mode can be realized using a calorimeter device according to the method of accelerating rate calorimetry (ARC). The main purpose of such a device is to study scenarios and thermal runaway reactions. A short description of the adiabatic mode is “no heat in – no heat out”.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.
