The CYCLOPS Z - Purge Indicator for use in Division 2 and / or Zone 2 hazardous areas, which monitors purge pressure in one (1) pressurized enclosure. Type "Z" purging reduces the classification within a protected enclosure from Division 2 and / or Zone 2 to non-hazardous. For Z type purging; failure to maintain pressure within the protected enclosure is detected locally by a green LED visual indicator and for remote monitoring a dry contact is standard on the CYCLOPS Z - Purge Indicator. The dilution 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 purge pressure. 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 230VAC. The CYCLOPS Z - Purge Indicator mounts directly to the enclosure being purged. This means no additional holes, sheet metal, or plumbing is required for installation of the CYCLOPS Z - Purge Indicator.
