SIPHON HEAT DISSIPATION CHARTS
These graphs represents the heat dissipation based on results of a specific laboratory test.
These results may vary in the field based on multiple factors such as ambient temperature, type
of process media and/or velocity. This data set is to be used as a reference point only.
These test results are based on an ambient temperature of 68°F.
