Purge & Pressurization System, 6000 Series, 6000-DV-S2-UN-WH-AC

6000-DV-S2-UN-WH-AC, Purge & Pressurization System, 6000 Series

• Certified for Class I, Class II, Division I; Zone 1 / Zone 21 to nonhazardous
• Intrinsically safe electrical/pneumatic manifold assembly
• Intrinsically safe user interface for programming and monitoring the system
• Enclosure volume up to 450 ft3 (12.1 m3)
• Control Unit monitors system operation and controls enclosure power
• Universal mounting (brackets included)
• 316L stainless steel Type 4X enclosure

The EPV‑6000 vent exhausts excess pressure from the enclosure and measures flow and pressure during operation. The 6000 series vent has a pressure transducer and thermal flow sensor that is connected to the 6000 EPCU. It is intrinsically safe through the galvanic isolation barrier within the 6000 EPCU.

The purpose of the Pepperl+Fuchs 6000 series Type X & Ex px, Class I/II, Division 1 / Zone 1/21 enclosure protection system is to allow the use of general purpose or nonrated electrical or electronic devices located in general purpose enclosures instead of explosionproof/flameproof, Type 7 or 9 / Ex d enclosures or other means of protection for the rated area. Other purposes include heat, moisture, and dust contamination prevention. 

The 6000 series Type X & Ex px purge and pressurization system protects general purpose equipment mounted in a standard enclosure. This allows the enclosure to be located and the equipment operated in a hazardous area. The hazardous area classification can be Class I, Class II, Division 1 / Zone 1, Zone 21. The 6000 series operates by controlling and monitoring compressed instrument air or inert gas through the protected enclosure(s) so as to remove and prevent the accumulation of flammable gas, vapors, or dust.

The 6000 series system features these main parts:

• Electronic processor (EPCU) housed in an explosionproof enclosure 
• I.S. electrical/pneumatic manifold assembly 
• I.S. user interface for programming and monitoring the system 
• 316L stainless steel (UNS S31603) type 4X IP66 enclosure for EPCU and connections (not included with component kit)
• Intrinsically safe pressure relief vent with flow and pressure monitoring at the exhaust. 

The user interface allows programming of up to 4 switch inputs, temperature modules, enclosure power contacts, 2 auxiliary outputs, and various operational functions. Through the user interface menus, configuration of the standard information for setup and operation of a system (purge time, flow rates, pressures, enclosure size, etc.) are easily programmed. Additional features allow inputs for system bypass, enclosure power on/off, temperature overload and activation of rapid exchange flow for cooling or auxiliary relay for separate cooling source, delay power shutdown, and more. The two auxiliary contact outputs can be configured to activate on most of the input switches or any of the configured alarm states for pressure, flows, and temperature. The power for the solenoid valve on the manifold unit, inputs, the user interface controller (UIC), and EPV-6000 vent are provided by the EPCU through the internal galvanically isolated intrinsic safety barrier. No additional I.S. barrier is required. The adjustable mounting bracket and the universally mountable vent make the 6000 system easy to install horizontally or vertically onto the enclosure. A component kit is available for custom installations that fit specific customer needs.The 6000 control unit can monitor multiple enclosures and control and accept inputs from two (2) EPV6000 vents. The 6000 series provides a complete system for purging and pressurizing enclosures for hazardous location operation.
