Many of our control panels are in the field area where summer temperatures outside reaches 45 Deg C. Some panels also have sensitive electronic cards like Driver card for a Servo Hydraulic Control Valve. The panel has other electrical and power supply components too. Power supplies' heat sinks are also at high temperature.

I propose to cool the panel by allowing 7 Kg/cm2 of dry (dew point value around -55 Deg C) Instrumentation air to bleed through a very small orifice inside the panel. Will this scheme work? If yes, what can be possible risks in doing it?
