MiniPurge® Control Unit DataAction on Pressure Failure: Alarm and Trip (isolate power to pressurized enclosure), useradjustable Alarm Only.Type of Operation: Automatic leakage compensation using the Closed Loop AutomaticPressurization System (CLAPS System).Leakage Compensation Capacity: 500 NI/min initial maximum pressurized enclosure leakage.Enclosure Material: Stainless Steel 316L.Mounting Method: Wall mounting straps. Fixing holes as per drawing.Temperature Limits: -20oC to +55oCCompressed Air Supply: Clean, dry, oil free air or inert gas. Refer to Air Supply Quality sectionin Installation of the System.Supply Pressure: 4 to 8 barg (60 to 115 psi).Main Regulator: Set at 4 barg, 40 μm automatic drain supply inlet filter.Logic Regulator and Gauge: Fitted and set to 2.3 barg (33 psi).Process Connections: Purge supply and outlet to pressurized enclosure 1/2” NPT female.Minimum supply line 13 mm (1/2”) ID tube, inlet sized appropriately forflow rate.Reference points & signals 1/8” NPT female, minimum 6 mm pipe tobe used.Visual Indicators: Alarm (Red ) / Pressurized (Green ).System Purging: 4 LEDs that flash sequentially to indicate elapsedtime (black when not purging)./PA Terminal Box: Glass reinforced polyester box with terminals and accessible cableglands.
