Product Description

Best Purging Systems Type Y and Z Pressurization Units protect electrical equipment in Class I and Class II Hazardous Locations. When connected to a supply of protective gas these models will supply, regulate and monitor the protective gas supply to a protected enclosure; and are UL Listed and designed to meet or exceed NEC – NFPA 70, NFPA 496, EN 50016 and IEC 60079-02 requirements.

Each Unit features a regulator to set enclosure pressure along with a color-coded analog differential pressure indicator that displays enclosure pressure.  Our Vertical and Horizontal Configuration Units also feature a Differential Pressure Switch available in several styles to provide a signal to indicate enclosure pressure loss.

When utilized for Type Z applications, these Units reduce the hazardous location rating inside the enclosure from Division 2/ Zone 2 to non-hazardous. This allows non-rated equipment to operate in Division 2/ Zone 2 areas.

When utilized for Type Y applications, these Units reduce the hazardous location rating inside the enclosure from Division 1/ Zone 1 to Division 2 / Zone 2. This allows Division 2/ Zone 2 equipment to operate in Division 1/ Zone 1 areas.

IMPORTANT NOTE:  Model RR Redundant Regulators installed upstream of the Pressurization Unit or Model PV Spark Arresting Purge Vents installed on the protected enclosure are required for safe operation.
