What Is Purge And Pressurization?

1.	What Is Purge And Pressurization?
Answer» Purge and pressurization enables you to use any electrical equipment inside an enclosure in a hazardous location. Before control units power-up electrical equipment, they first flush hazardous GAS and dust from the enclosure or panel, cabinet, motor HOUSING, etc., with clean uncontaminated AIR. The equipment inside the enclosure does not require approvals or certifications. Generally, we purge with instrument-grade compressed air. The flow RATE and duration depends on the enclosure volume and national &AMP; international standards. Some companies purge with nitrogen – you can use other inert gases but nitrogen is commonly available.
