Can I use this in a marine heat exchange for the intake water side?
Asked by inqusitive November 7, 2019Make sure do this with the engine running. Otherwise the muffler may back up into the exhaust manifold.
has anyone tested this with a refractometer? If so what was the reading?
Asked by John November 1, 2019The SouthWin RV Antifreeze -50 , Model# 147005, is intended for potable water systems and not combustion engines. The product is formulated to protect to -50 by preventing long ice crystals from forming, thereby reducing the swelling of the frozen product. It is not designed to remain liquid at sub zero temperatures, but rather to not expand as it freezes. There is still some expansion as the smaller ice crystals form, but it is maintained at a minimum. The product is a mixture of several ingredients and consequently cannot be measured accurately with a refractometer like you would an engine antifreeze.
