Thermal Growth
The compressor's cast iron frame thermally grows between ambient (cold) to
normal (hot) operating conditions. The expected vertical change, from the bottom
of the frame foot to the compressor's crankshaft center line position, is shown
in "Table 13". These thermal growth figures may need to be prorated, if the
anticipated difference between cold and hot operating conditions is more or less
than 100°F. (38°C).
