Cooling in prefabrication – why is it so important?

In prefabricated control cabinets and low-voltage switchgear, reliable cooling is crucial for maintaining system efficiency and the service life of the installed components. Overheating devices lead to reduced performance, failures and even damage to entire systems. Therefore, adequate cabinet ventilation is one of the basic elements that must not be overlooked during the prefabrication process.

ELTRON offers AC fans and ventilation accessories by Salzer, designed for effective and reliable cooling of industrial cabinets and enclosures.
