Injection molding water heater
WebbAn important “rule of thumb” is that the capacity of a chiller is reduced by 2% per ˚F below 50˚F. So, if the temperature is reduced by 5˚F to 45˚F, the chiller capacity is lowered by 10%. This can cause the need to increase chiller capacity in order to properly cool the mold. On the other hand, raising the temperature above 50˚F will ...
