Purge Solutions Now Have Certification Issued by UL for Its CYCLOPS Y and Z -Purge Indicators
Purge Solutions has been issued certification by UL, file number E347373, for its CYCLOPS Y Z – Purge Indicator purge / pressurization systems. These systems are low cost, are simple to install, are easy to use, are highly reliable and are maintenance free. Standard features include: an enclosure exhaust vent which is incorporated in the indicator casing, a local LED and remote dry contact status alarm. System options include a choice of 12 or 24 VDC and 115 or 230 VAC, anodized aluminum or stainless steel, continuous dilution or leakage compensation purge gas inlet kits.Â
The CYCLOPS Z – Purge Indicator is used to provide safe monitoring of electrical equipment in Division 2 and Zone 2 hazardous areas. The CYCLOPS Y – Purge Indicator is also used to provide safe monitoring of electrical equipment in Division 1 and Zone 1 hazardous areas. Both units can be used to prevent the possibility of fire or explosion inside the enclosure of energized electrical equipment. A protective gas supply is used to dilute potentially flammable materials to an acceptable level, creating a safe area for the electrical equipment within the enclosure. Positive pressure prevents the ingress of flammable materials in the surrounding atmosphere from entering into the enclosure, as long as positive pressure is maintained. After the enclosure is purged, power may be manually applied to the protected electrical equipment.
The CYCLOPS Y and Z – Purge Indicator provides an objective evidence of the presence of adequate positive purge pressure within the electrical equipment enclosure. A normally open differential pressure switch continuously compares the pressure inside the monitored enclosure with respect to the atmospheric pressure surrounding the enclosure. When the monitored enclosure registers a required pressure above the reference atmospheric pressure, a manually controlled dilution time cycle may then begin. After the manual dilution time cycle has elapsed and the required enclosure pressure is being maintained, power may be manually applied to the electrical equipment within the purged enclosure.
The CYCLOPS Y and Z – Purge Indicator is designed to indicate the presence of purge pressure from one pressure reference point. Several electronics enclosures can be installed in series with purge gas being introduced into the first enclosure and the CYCLOPS Y or Z – Purge Indicator monitoring the last enclosure in the series. Multiple electronics enclosures can now be monitored using only one CYCLOPS Y or Z – Purge Indicator and purge gas inlet source. A required pressure inside the monitored enclosures must maintain higher than the atmospheric pressure surrounding the enclosures. This application ensures that hazardous materials are not going to ingress into the pressurized and now protected electronics enclosures. If any of the enclosures installed in the series doors are opened, pressure will show to be below what is required in all enclosures.
