The following should be used to cool the electrical cabinet:<br />

Heat exchangers: They prevent contaminated air (mist, metallic dust in<br />

suspension, etc.) from getting into the electrical cabinet hence eliminating<br />

the chances of accumulating particles, condensation, etc. in the<br />

cooling circuits of the DDS system modules.<br />

If it is impossible to use heat exchangers, then:<br />

Air extraction system: They prevent the air from entering the electrical<br />

cabinet with a fan.<br />

MANDATORY. The ventilation for the electrical cabinet must be enough<br />

to dissipate the heat generated by all the devices and components working<br />

inside.
