Ex Pressurised Enclosures

  • The SPZ range of ex pressurised enclosures is available in different sizes and designs. All enclosures are certified for use in ex hazardous areas (Zone 1/21 and Zone 2/22).

    Ex Pressurised enclosures allow the installation of non ex-components directly in the hazardous area. The enclosures are certified and ready to use immediately after installation.

    The control unit works without a flushing phase and automatically starts when the gas detector has checked for potentially explosive gases. The elimination of flushing time and the use of flushing gas make´s the operation particularly economical.

Components used in these pressurised enclosure systems:

 

*  QPU Controller
The QPU controller monitors air pressure within the pressurised enclosure, cabinet or device. Once the cabinet or enclosure pressure builds up it allows the non ex devices to be activated.

*  Gas Detector
This preset gas detector measures gas within an enclosure. If no gas detected, the QPU Controller is activated.
  
*  Leakage valve controller
Designed to work with the QPU Controller, this automatically compensates for leakage in pressurised enclosures.

*  PRE Pressure Regulators

Diaphram pressure regulator controls input pressure to a constant working pressure.

*  Interface module
Designed to seperate active cables like RJ45, USB or directly via terminal. Shuts off active datalines within the enclosure if pressure is lost.
