sigma T H E R M - S

Description : sigma T H E R M®- S is a synthetic organic heat transfer fluid based on Alkylated aromatic. Application : Indirect closed heat transfer systems from - 80 °C to 160 °C in liquid phase without pressurization of system and with proper pressurization up to 300°C This single fluid is used for challenging requirement of Pharmaceutical, Fine Chemicals and other industries where two different circuits with different fluids are there for cooling and heating purpose. It replaces traditional duel steam & glycol or steam & brine systems. Benefits : • Eliminates duel fluids for heating and cooling. • Long Life. • Cost Effective Solution • Trouble free operation Gasket Material Compatibility : sigma T H E R M®- S has an acceptable compatibility when used within the temperature and pressure limitation of the following polymers or gasketing materials: Acetal, Aramid Fiber, Chemraz (FFKM), Epoxy, Fluorocarbon (FILM), Fluoroelastomer, Glass Fiber, Gylon Style 3500, 3504 & 3510, Kalrez, PEEK, Polytetrafluoro-ethylene, Teflon (All) , Teflon Encapsulated Silicon, Teflon Encapsulated Viton, Teflon Impregnated Fiberglass, Kel-F (CTE), Viton, Resin Impregnated Carbon Graphite, Typical Properties : Composition Alkylated Aromatics Appearance Clear to Light Yellow Max.
