The CYCLOPS Z – Purge Indicator for use in Division 2 and Zone 2 hazardous areas, which monitors minimum overpressure pressure in one enclosure. Type Z purge and pressurization reduces the classification from Division 2 or Zone 2 to non-hazardous.
Failure to maintain pressure within the protected enclosure is detected locally by a green LED indicator and for remote monitoring a dry contact is standard on the CYCLOPS Z – Purge Indicator. The purge time is a manual operation and once the enclosure has been purged of ignitable or flammable concentrations, only positive pressure 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.
The enclosure exhaust vent is an integrated part of the CYCLOPS Z – Purge Indicator casing, which comes standard in anodized aluminum and as an option in 316 stainless steel, with voltage options in 12 or 24 VDC and 115 or 230 VAC. The CYCLOPS Z – Purge Indicator mounts directly to the enclosure wall or door. This means no additional holes, sheet metal, or tubing for plumbing is required
The CYCLOPS Z – Purge Indicator provides an objective evidence of the presence of adequate minimum overpressure within the enclosure. When the monitored enclosure reaches the required minimum overpressure above the reference atmospheric pressure surrounding the enclosure, CYCLOPS’s green LED will light up. A manually controlled time delay may then begin. Typically, a minimum time delay is specified to ensure that at least four (4) enclosure volumes for Division or five (5) enclosure volumes is exchanged before power is manually applied to the electrical equipment inside the purged and pressurized enclosure.
