This graph 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.
