The SmartPurge II is our most advanced purge unit. First it purges the enclosure of hazardous gas, then maintains a positive gas-pressure preventing hazardous gas entering the enclosure.
Install uncertified equipment in Class I Zone 1, Zone 1 hazardous areas. The SmartPurge II features:
- Universally Applicable: Leakage compensation or continuous flow purging;
- Quickly Purge: Reduce downtime, due to high air-flow capacity:
- Leakage Compensation 110-510 NI/min, 3.9-19.1 cu ft/min;
- Continuous Flow: 10-510 NI/min, 0.35 – 19.1 cu ft/min.
- Field Programmable:
- Field program timers and control signals to connect & disconnect power depending on purge system status via interposing relays. Relays rated up to 6A at 250 VAC or 5A at 30 VDC.
- Configurable inputs/outputs
- Two selectable alarms;
- Auxiliary inputs for override keyswitch, door switch, or intermediate pressure switch.

SmartPurge II Additional Components
When ordering, select the appropriate system components:
- Cable Glands – SP2-GK: Select the most suitable cable glands for your hazardous area application. IECEx and ATEX certified cable glands supplied separately to the SmartPurge II controller unit.
- Digital Valve – SP2-DV: This intrinsically safe device switches between purge-flow and leakage compensation.
- Continuous Flow Kit: SP2-CF: For Continuous Flow applications. This is suitable for low flow rate applications. e.g. Cooling, or diluting hazardous gas generated inside the enclosure, requires a continuous air flow.
