Fauske Introduces Emergency Relief System Tool (FERST) Software

Posted by Fauske & Associates on 10.30.19

By Technical Lead Benjamin C. Doup, PhD and Chief Technology Officer Ken Kurko

FERST-logoFauske & Associates, LLC (FAI) has updated its emergency relief sizing tools with FERST software powered by CHEMCAD. FERST is the complete package combining the practical and easy-to-use interface and calculation methods from FAI’s PrEVentTM (Practical Emergency Vent Sizing) software, the direct use of temperature rise rates from low Φ-factor calorimetry data from FAI’s VSDS (Vent Sizing Dynamic Simulation) software and the material property, thermodynamic, and software development expertise from ChemstationsTM.
