Purge Units

Overview

Best Purging Systems Type Y & Z Purge Units are intended to protect electrical equipment inside Class I enclosures up to 250 cubic feet. Best Models YZ102, YZ103, and YZ104 operate by supplying clean instrument air or inert gas to remove flammable gases within the protected enclosure.

When used for Type Y applications, these Purge Units allow Division 2 / Zone 2 rated equipment to operate in Division 1 / Zone 1 hazardous areas. These units reduce the classification within the protected enclosures from Division 1 / Zone 1 to Division 2 / Zone 2.

When used for Type Z applications, these Purge Units allow nonclassified equipment to operate in Division 2 / Zone 2 hazardous areas. These units reduce the classification within protected enclosures from Division 2 / Zone 2 to Unclassified.

Type Y & Z Purge Units protect delicate equipment against combustion, heat, moisture, dust build-up and corrosion. Best Purging Systems offer the safest and most economical means of installing electrical equipment in hazardous locations, eliminating the need for explosion-proof boxes and intrinsic safety barriers. Best of all, they’re designed to meet or exceed NEC – NFPA 70, NFPA 496, EN 50016 and IEC 60079-02 requirements!
