1. A temperature gradient control system for a double wall casing of a compressor, wherein the double wall casing comprises an inner casing and an outer casing and wherein a flow of air is pulled through the double wall casing via a pressure differential from the compressor when the compressor is operating, the temperature gradient control system comprising:
upper discharge piping in communication with a top of the double wall casing;
the upper discharge piping comprising an upper modulation valve;
lower discharge piping in communication with a bottom of the double walled casing;
the lower discharge piping comprising a lower modulation valve; and
wherein the upper modulation valve and/or the lower modulation valve modulate the flow of air pulled through the double wall casing to reduce a temperature gradient across the outer casing.
