Purge Solutions, Type Y & Z Purge / Pressurization Systems are ATEC, CEC, IECEx, & NEC Certified for Global Installation and Use


The CYCLOPS Y & Z - Purge Indicator purge / pressurization systems have a low cost, are simple to install and use and are highly reliable and maintenance free. Standard features include an enclosure exhaust vent which is incorporated in the indicator casing and 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 and continuous dilution or leakage compensation purge gas inlet kits.

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 used to provide safe monitoring of electrical equipment in Division 1 and Zone 1 hazardous areas. purgesolutions.com/index.html 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 register's 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. More Product info is available at purgesolutions.com/index.html

The exhaust vent which is incorporated into the CYCLOPS Y or Z - Purge Indicator casing can exhaust purge gas from enclosures with volumes up to 15 cubic feet (425 liters). For enclosures with volumes above 15 cubic feet (425 liters) and up to 200 cubic feet (5,663 liters) an additional exhaust vent will be required to properly vent the larger volume of purge gas from the enclosures safely.

The CYCLOPS Y or Z - Purge Indicator uses two different purge gas methods to dilute the electronics enclosures and maintain the required pressure; continuous dilution or leakage compensation. Continuous dilution is a method that the same volume and pressure of purge gas are maintained during and after the dilution time cycle. Continuous dilution is normally used for maintaining and controlling heat buildup from the electronics within the pressurized enclosure by continuously exchanging purge gas through the enclosure to atmosphere. Purge Solutions offers three sizes of continuous dilution models a Small Continuous Dilution Purge Gas Inlet Kit for enclosures with a volume up to 15 cubic feet (425 liters), a Medium Continuous Dilution Purge Gas Inlet Kit for enclosures with volumes up to 75 cubic feet (2,125 liters) and a Large Continuous Dilution Purge Gas Inlet Kit for enclosures with volumes up to 200 cubic feet (5,663 liters). All three Small, Medium and Large Continuous Dilution Purge Gas Inlet Kits are available in materials of anodized aluminum or 316 stainless steel.

The second purge method offered by Purge Solutions for the CYCLOPS Y or Z - Purge Indicator is leakage compensation. During the dilution cycle leakage compensation allows a higher volume of protective gas supply to speed up dilution time, permitting a more-rapid application of initial power or restoration of power to protected electrical equipment, after service. When the dilution cycle has elapsed, the large volume of purge gas will be manually turned off. A volume of purge gas larger than the leak rate of the electronics enclosure will be introduced into the enclosure to maintain required pressure.

Leakage compensation is normally used to conserve purge gas when utilities are at a premium. Purge Solutions offers three sizes of leakage compensation models a Small Leakage Compensation Purge Gas Inlet Kit for enclosures with a volume up to 15 cubic feet (425 liters), a Medium Leakage Compensation Purge Gas Inlet Kit for enclosures with volumes up to 75 cubic feet (2,125 liters) and a Large Leakage Compensation Purge Gas Inlet Kit for enclosures with volumes up to 200 cubic feet (5,663 liters). All three Small, Medium and Large Leakage Compensation Purge Gas Inlet Kits are available in materials of anodized aluminum or 316 stainless steel.
