Pepperl+Fuchs Purge Pressurization Systems Type X Purge

Type X

  • Type X purge systems reduce the classification within the protected enclosures from Division 1 to non-hazardous. General-purpose equipment can be operated within the protected enclosure.
  • Note: Vents are required for most purge enclosures
  • The Pepperl+Fuchs Type X purge system is fully automatic and performs critical purging, pressurization and monitoring of the protected enclosure. It is designed according to NFPA 496 and ISA 12.4 standards.
Pepperl+Fuchs Purge Pressurization Systems Type Y Purge

Type Y

  • Type Y purging systems  reduce the classification within the protected enclosure from Division 1 to Division 2. All equipment used within the enclosure must be Division 2 rated.
  • Note: Vents are required for most Type Y purge enclosures
  • The Type Y purge system:
    • Allows Division 2 rated equipment to be operated in a Division 1 location
    • Controls purging, pressurization & monitoring pressures
    • Rated for Class I/ II, Division 1 to Division 2 area applications
    • Purge enclosure sizes to 450 cu. ft.
    • UL, cUL, FM classifications
    • Conforms to NFPA 496 and ISA 12.4 standards

Pepperl+Fuchs Purge Pressurization Systems Enviro-Line Pressurization

Enviro-Line Pressurization Systems

  • Enviro-Line purging units is an enclosure pressurization system for non hazardous areas that operates on a supply of compressed instrument air or inert gas. It regulates and monitors the pressure within the sealed enclosure at a constant pressure in order to prevent the accumulation of damaging and caustic gases and dusts.
  • The elimination of these gases and dusts extends the life of expensive electrical equipment and instrumentation placed within the Enviro-Line purging unit.
  • Due to higher pressures inside the electrical enclosure, corrosive environments remain outside. The system maintains a constant 0.5" water pressure inside the enclosure for protection against gas and/or dust.
