WebAmerican Chillers heat exchangers are engineered for full rated capacity with the use of 30% glycol solutions. Our heat exchangers start out with 30% more surface area capacity than the heat exchangers used by other … WebSep 13, 2010 · If a heat exchanger system requires a 30% water-propylene glycol mix, use that in the calculation. Likewise, if your cooling system design requires a 50% Ethylene glycol-water fluid, then the chiller and coil designs should be based on that fluid. This way the heat transfer correction is built into the selection.
