Low viscosity Readily biodegradable Low pour point Non-volatile Halogen free Non-toxic Dielectric Liquid Technical Brochure INTRODUCING MIVOLT DF7 A new, immersive approach to cooling electrical systems. MIVOLT DF7 is a new liquid for the immersive cooling of electrical systems. The unique chemistry of MIVOLT DF7 allows it to act as a dielectric coolant, removing heat directly from all areas of a component. Not only does this liquid have low viscosity and readily biodegradable status, but as a single phase coolant it does not require any of the complex systems necessary to evaporate and condense multiphase uids. Key Features: Low viscosity Readily biodegradable Extremely low pour point -75C Non-volatile Halogen free Non-toxic MIVOLT DF7 PROPERTIES Thermal Properties Density at 20C Specic Heat at 20C Kinematic Viscosity at 20C Thermal Conductivity at 20C Coefcient of Expansion at 20C Cold Behaviour Kinematic Viscosity at -10C Kinematic Viscosity at -30C Pour Point Fire Safety Flash Point Fire Point Auto-Ignition Temperature Environmental Impact Biodegradability Global Warming Potential Ozone Depleting Potential Chemical Properties Neutralisation Value Net Caloric Value Dielectric Properties AC Breakdown Voltage Volume Resistivity at 20C Units kg/m3 J/kg-K mm2/s W/m-K 1/K mm2/s mm2/s C C C C GWP ODP mg KOH/g MJ/kg kV G.m Method ISO 3675 ASTM E1269 ISO 3104 ASTM D7896 ASTM D1903 ISO 3104 ISO 3104 ISO 3016 ISO 2719 ISO 2592 ASTM E659 OECD 301 IEC 62021-2 ASTM D 240-02 IEC 60156 IEC 60247 MIVOLT DF7 916 1907 16.4 0.129 0.00080 87.4 534 -75 194 218 385 Readily Biodegradable <1 0 <0.03 33.5 >75 >90 2 MIVOLT DF7 MATERIALS COMPATIBILITY Based upon testing with ester based dielectric liquids.

Certain amorphous polymers or those with a low degree of crystallinity (e.g. Polycarbonate, ABS and CPVC) may exhibit environmental stress cracking in contact with MIVOLT DF7. Use of these polymers for pipework or mechanically stressed components in contact with the liquid is not recommended. ENVIRONMENTAL HEALTH & SAFETY We advise that you read through the MIVOLT DF7 Material Safety Data Sheet (MSDS) before using this liquid. Please contact our technical team to request a copy.
