LLC (FAI) Rapid Screening Calorimeter

LLC(FAI)Quick screening calorimeter（ARSST^TM）

Fauske & Associates,LLC(FAI)Quick screening calorimeterIt is a low thermal inertia calorimeter used to obtain critical process design data. Based on beingOSHARated as'Good Engineering Practice*'ofDIERSThe two-phase flow technology can obtain low thermal inertia data and be used forDIERSDesign of release system.

Product Introduction

ARSSTEnable users to quickly obtain reliable adiabatic data for various safety applications, including characterizing thermal stability and reactive chemistry. The experimental data includes adiabatic temperature and pressure change rate. Due to its low thermal inertia, it can be directly applied to process amplification, determination, and process safety management（PSM）Relevant discharge port dimensions, quenching tank design, and other discharge system design parameters.

ARSSTTMTesting is used to simulate some out of control situations, such as cooling failure, mixing failure, material misfeeding, rapid feeding, intermittent pollution, external fire heating, etc. FromARSSTTMThe test data obtained key information such as the rate of temperature and pressure rise during the uncontrolled reaction process, providing reliable energy and gas release rates that can be directly applied to full-scale process condition testing.

ARSSTTMIt is a fast screening calorimeter with simple operation and low cost, which can quickly and safely identify potential chemical reaction hazards in the process industry.FAIManufacturing and salesARSSTTM, and provide customized options such as high-pressure sample cell and flow dynamic detector(FREDTM).FAIWe also provide commonly used consumables for a long time, such as testing, heaters, sealing rings, and thermocouples.

Product Specifications

ARSST^TMUsually in a volume of10mlUsed in the lightweight quartz testing pool5-10The sample of grams. The testing pool is equipped with a belt heater(Used to heat samples through pre programmed temperature scanning)Then install it in350In a pressure resistant chamber of milliliters. Testing is usually conducted using an open testing method, where the testing unit is connected to the pressure chamber and inert back pressure is applied to the chamber to prevent sample evaporation.
