Heat Transfer Fluid (Tentative) S' MCS-523 MCS-523 is a low temperature, fire-resistant heat transfer fluid formulated specifically for practical pumpability at -20 F. MCS-523 permits installation of a non-pressurized system operating with a liquid that has no fire point, and will not support combustion. The recommended operating range of MCS-523 is -20 F. to 400" F. and will not show measurable change after years of exposure at such temperatures. The fluid is non-corrosive with all common metals used in heat transfer system design.
