Minimises consumption of purge gas.  \nATEX, IECEx, cULus, UKEX, PESO, CCC & INMETRO certified.  \nSimple installation  \nAll-in-one unit contains the purge gas inlet, overpressure relief valve and control system – eliminates the need to install and connect multiple components.  \nSimplest configuration – setting the purge timer is the only user input.  \nThe SmartPurge Z is a fully certified purge and pressurization system for Zone 2 and Class 1 Div 2 hazardous area applications. When fitted to a suitable enclosure, the system enables standard uncertified electrical equipment to be operated safely in a hazardous location.  \nThe SmartPurge Z uniquely contains all elements of a purge and pressurization system; control unit, purge inlet and purge outlet with an overpressure relief valve, in a single robust GRP housing. Additionally, the system provides automatic switching between purge mode and control of leakage compensation flow rate.  \nSimple to install and configure, and able to purge a wide range of enclosure sizes, SmartPurge Z is ideally suited for use with OEM systems , gas analysers, DCS systems, and other electrical enclosures.  \nHow does it work?  \nWhen purge is started the system supplies a high flow of purge gas, usually compressed air, and monitors that flow at the outlet valve. Providing that flow is sufficient, the purge timer is started. The purge timing is simple to set during commissioning of the unit. Purging in progress is indicated by flashing green LEDs.  \nAfter the purge time is complete, the purge gas flow stops and the system switches to Leakage Compensation mode, controlling a lower flow of purge gas, sufficient to compensate for any enclosure leakage. This flow rate is automatically adjusted in real time to compensate for enclosure leakage, including any change in enclosure integrity. This pressurized mode is indicated by solid green LEDs.  \nThe enclosure pressure is continually monitored. Any fall below the low pressure alarm level is indicated by red LEDs. Contacts are included to permit connection to a remote alarm system.  \nTypical Applications  \nControl panel purge Process gas analysers DCS systems  \nLabel printers; PCs; monitors  \nSimplifying Complexity.  \nDelivering Safety.  \nMKTG_17042026_V1 .2  \nSmartPurge® Z Product Datasheet Zone 2, Class I Div 2  \nSpecifications  \n\n| Hazardous environment | Zone 2, Class I Div 2 |\n| --- | --- |\n| Ambient temperature range | –20°C to +58°C (-4°F to +136°F) |\n| Hazardous area approvals | IECEx; ATEX; cULus; UKEX; PESO; INMETRO; CCC |\n| Purging mode | Automatic Leakage Compensation |\n| Purge gas supply | 4.0—5.0 barg (58—72 psig) instrument air supply (or other inert gas) .
