Control.com - Nerds in Control

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?

Dear Jairam,
