InPower Battery Thermal Management, heat transfer fluids must do more than remove heat—they must keep battery packs, modules, and test platforms within a narrow and stable operating window under fast charging, high discharge, and low-temperature start-up conditions. Chemie’s portfolio supports this full thermal spectrum.E200delivers ultra-low-temperature pumpability from-85 to 230°Cwith1.20 mm²/s at 40°Cand apour point below -85°C, making it suitable for extreme cold-start and laboratory control loops.E230andE250, with operating ranges of-60 to 230°Cand-40 to 250°C, combine low viscosity, strong thermal stability, and long service life for responsive circulation and efficient heat exchange. For broader thermal margins,E330offers-49 to 315°C,4.04 mm²/s at 40°C, and a-68°C pour point, helping maintain stable performance in demanding heating-cooling cycles. In liquid-cooled battery systems,MEG,NF,BF, andPFprovide practical glycol-based options:MEG (-40 to 110°C),NF (-60 to 115°C),BF (-35 to 110°C), andPF (-50 to 160°C)are designed for open or closed circuits, withno flash point and non-flammable characteristicson the water-based series, supporting safer operation, efficient heat removal, and dependable long-term battery protection across industrial facilities
