Purpose
Fuchs' Bebco EPS System’s purpose is to allow
the use of general purpose or nonrated electrical or
electronic devices, with exception to devices which
produce excessive heat, utilize combustible gas, or
expose arcing contacts to the hazardous atmosphere,
in Type 4 or 12 enclosures in the place of explosion
proof Type 7 or 9 enclosures. Other purposes include
heat, moisture and dust contamination prevention.
Description
Model 1001B is an enclosure pressurization system that
operates on a supply of compressed instrument air or inert
gas. It regulates and monitors pressure within sealed
(protected) enclosures to prevent combustible dust
accumulation. In Class II areas, the system maintains a
“safe” (1.0") pressure. This process reduces the hazardous
(classified) area rating within the enclosure(s), in
accordance with the NEC - NFPA 70, Article 500, NFPA 496
and ISA 12.4
