ADDITIONAL PRODUCT DETAILS
Purge and Pressurization is a protection method used with Type 4, 4X and 12 (IP54 recommended minimum) enclosures. The enclosure is initially purged to remove any internal explosive gases or dust. Once this is accomplished, the enclosure is pressurized with a protective air or inert gas supply. This provides a positive internal enclosure pressure which keeps any external explosive gases or dust from entering the enclosure. The two methods of purge and pressurization offered are Leak Compensation and Continuous Flow.
Leak Compensation maintains positive pressure by compensating for losses. System consists of Control Unit and Relief Valve. Certification Type Y and Z models: • Flush (internal) or external mount models • Local visual alarm indicator and dry contact output for remote alarm • Typically recommended for enclosures with volume of 60 Ft3 or less. Certification Type X Model: • Provides power disconnect when pressurization is lost or not attained • Provides automatic purge process • External mount • Local visual alarm indicator and dry contact output for remote alarm • Typically recommended for enclosures with volume of 60 Ft3 or less.
Continuous Flow provides positive pressure via continuous protective air flow through the enclosure. System consists of Control Unit, Calibrated Outlet Orifice and Relief Valve. Certification Type Y and Z Models: • Flush (internal) or external mount models • Local visual alarm indicator and dry contact output for remote alarm • Typically recommended for enclosures with volume of 17 Ft3 or less
For all IEC and ATEC applications, the final or complete integrated assembly must be submitted to a notified body for certification.
