CAUTION: The safe handling and operation of a purge and
pressurization system requires basic knowledge of safety standards
with additional training and experience to work on explosion
protection equipment.
CAUTION: Applicable permits must be obtained and appropriate
precautions must be taken to prevent possible injury to personnel or
equipment damage when installing or maintaining this equipment.
WARNING: Enclosures being monitored by a type Z – Purge System
must not be opened unless power is disconnected from the electrical
equipment within enclosure or the area is known not to contain
explosive or combustible materials.
CAUTION: This purge unit has an operating temperature of 85°C or
T6 temperature class. This operating temperature shall be considered
when mounted to the enclosure it will be monitoring.
NOTE: This equipment is suitable for use in Class I, Division 2,

Section 3
Introduction
Description:
Type Z purge / pressurization reduces the classification within a pressurized protected
panel from Division 2, Zone 2 or Zone 22 to nonhazardous. Failure to maintain
minimum overpressure within the protected enclosure shall be detected and
communicated by an indicator and / or alarm. The purge cycle time is a manual
operation and once the panel has been purged of explosive concentrations, only a
minimum overpressure setting of at least 0.30 inch H2O (0.75 mbar) for explosive gas
atmospheres or 0.5 inch H2O (1.25 mbar) for combustible dust atmospheres is required
to be maintained within the enclosure and it is not necessary to remove power from the
protected equipment upon the loss of minimum overpressure within the protected panel.
The CYCLOPS Z – Purge Indicator is used to provide safe monitoring of electrical
equipment in Division 2, Zone 2 and Zone 22 hazardous locations, which can be used
to prevent the possibility of fire or explosion inside the panel of energized electrical
equipment. A protective gas supply is used to purge potentially flammable materials to
an acceptable level, creating a safe area for the electrical equipment within the
pressurized enclosure. Maintaining a positive pressure prevents the ingress of
potentially hazardous materials in the surrounding atmosphere from entering into the
enclosure. After the enclosure is purged, power may be manually connected to the
electrical equipment within the pressurized protected panel.
The CYCLOPS Z – Purge Indicator provides an objective evidence of the presence of
adequate minimum overpressure within the purge and pressurized panel. A differential
pressure switch continuously compares the minimum overpressure inside the monitored
enclosure with respect to the atmospheric pressure surrounding the enclosure. When
the monitored enclosure reaches a minimum overpressure for selected flow rate; purge
cycle time will begin. Typically, a minimum purge cycle time is specified to ensure that
at least four (4) times for Division and five (5) times for Zone the volume of free space in
the enclosure is exchanged before power is manually connected to the electrical
equipment inside the pressurized protected enclosure. (The number of exchanged
volumes may be higher in some situations).
The CYCLOPS Z – Purge Indicator are designed to indicate the presence of minimum
overpressure from one pressure reference point. Several enclosures can be installed in
series with protective gas being introduced into the first enclosure and the Z – Purge
Indicator monitoring the last enclosure in the series; multiple enclosures can now be
monitored using only one Z – Purge System. The minimum overpressure inside the
monitored enclosures must maintain at least 0.30 inch H2O (0.75 mbar) for explosive
gas atmospheres or 0.5 inch H2O (1.25 mbar) for combustible dust atmospheres higher
than the atmospheric pressure surrounding the enclosures. This ensures that
hazardous materials are not going to ingress into the pressurized and now protected
enclosures. If any of the enclosures installed in the series minimum overpressure goes
below the required 0.30 inch H2O (0.75 mbar) for explosive gas atmospheres or 0.5
9

inch H2O (1.25 mbar) for combustible dust atmospheres in any pressurized enclosure
the CYCLOPS Z – Purge Indicator will alarm. For proper selection of components for
your purge and pressurization application, refer to the Purge System Selection Wizard,
which can be found on the home page of our web site www.purgesolutions.com.
NOTE: Selection of Protective Gas Inlet Kit and flow rate should be
based on available protective gas volume at installation site; not on
maximum volume of protective gas that selected Protective Gas Inlet Kit
can supply.
The CYCLOPS Z – Purge Indicator uses two different methods to purge the
enclosure(s) and maintain a minimum overpressure of at least 0.30 inch H2O (0.75
mbar) for explosive gas atmospheres or 0.5 inch H2O (1.25 mbar) for combustible dust
atmospheres; continuous dilution or leakage compensation. Continuous dilution is a
method of maintaining the same pressure / flow rate during and after the enclosure has
been purged below the required lower explosive limit (LEL). The protective gas is
passed continuously through the enclosure at a minimum overpressure above that of
the required 0.30 inch H2O (0.75 mbar) for gas hazardous locations or 0.5 inch H2O
(1.25 mbar) for dust hazardous locations and discharged continuously to the outside
atmosphere through an exhaust vent. The same volume of protective gas is maintained
during and after the purge cycle time. Continuous dilution is normally used to help heat
buildup from the electronics within the pressurized panel by continuously exchanging
protective gas through the electronics panel to atmosphere. The maximum flow rate
that the Continuous Dilution Purge Gas Inlet Kit can supply is 80 SCFM (2,265 LM).
Continuous Dilution Protective Gas Inlet Kits are available in materials of anodized
aluminum or 316 stainless steel.
The second purge method offered by Purge Solutions, Inc. is leakage compensation,
which allows a higher volume of protective gas supply to be manually selected to speed
up the purge cycle time, permitting a more-rapid application of initial power or
restoration of power to protected electrical equipment, after service. When the purge
cycle has elapsed, the larger volume of purge gas can be manually turned off. A
volume of purge gas larger than the leak rate of the enclosure will be introduced into the
now protected enclosure to maintain a minimum overpressure of at least 0.30 inch H2O
(0.75 mbar) for gas hazardous locations or 0.5 inch H2O (1.25 mbar) for dust hazardous
locations. Leakage compensation is normally used to conserve protective gas when
utilities are at a premium. The maximum flow rate that the Leakage Compensation
Purge Gas Inlet Kit can supply is 80 CFM (2,265 LM). Both Leakage Compensation
Protective Gas Inlet Kits are available in materials of anodized aluminum or 316
stainless steel.
WARNING: Failure to heed the information in this manual may lead
to injury of personnel or equipment damage.
CAUTION: Electrical equipment components may be hot even when
power is not connected. Take appropriate precautions to prevent
