Whether you have a Class/ Division
or Zone rated area, P+F has a purge
or pressurization system designed for
you. Here in the US, the National Elec-
tric Code (NEC) denes Hazardous
Locations using the Class / Division
method. Here are 3 examples of P+F
Bebco purge types for Class / Division
rated locations.
Type X P+F Bebco Purge System:
The Type X purge system reduces
the classication within the protected
enclosures from Division 1 to non-haz-
ardous. General-purpose equipment
can be operated within the protected
enclosure in a Class I or II Division 1
location.
Type Y P+F Bebco Purge System:
The Type Y purging system reduces
the classication within the protected
enclosure from Division 1 to Division 2.
All equipment used within the enclo-
sure must be Division 2 rated.
Type Z P+F Bebco Purge System:
The Type Z purge system reduces
the classication within the protected
enclosure from Division 2 to non-haz-
ardous. General-purpose equipment
can be operated within the protected
enclosure in a Class I or II Division 2
location.

P+F Bebco
EPS® Division
Products are
designed to
supply one or
more protected
enclosures with clean instrument air or
an inert gas. Purge and pressurization
is one of the most exible EX protec-
tion methods, because it allows the
use of non-EX rated electrical equip-
ment to be utilized within the hazard-
ous area. This process removes
ammable gases or prevents the ac-
cumulation of ignitable dusts within the
protected enclosure. This method of
protection is not limited by the quantity,
conguration, power requirements, or
location of the protected equipment.
These purge systems are commonly
used for all applications involving basic
electronics, electrical equipment, mo-
tors and switchgear. In addition, these
systems can meet the demands of
rack mounted instrumentation, video
displays, PLCs, ControlLogix Systems,
computers, printers, recorders, mea-
surement gas analyzers and calibra-
tion equipment. Unlike explosionproof
enclosures, failure of a P+F Bebco
Enclosure Protection System does not
create an immediate danger. Another
benet of purging and pressurization
is the use of the standard Type 4/12
enclosure as the protected enclosure.
This saves money, weight, and space
over explosion-proof methods.
