MINI X-PURGE - LEAKAGE COMPENSATION
The MiniPurge system provides a full purge and pressurize
system for Class I Division 1 Gp A-D, Zone 1 (21) IIC
applications. When fitted to a suitable enclosure the
system enables regular electrical equipment to be operated
safely in a hazardous location.
Certified in compliance with IEC, European and American
standards and codes, the system controls purge and
pressurization process. Initially the system provides a high
flow of protective gas, usually compressed air. The flow
through the enclosure is verified by measuring where it
exits at the Relief Valve. Provided the flow is sufficient the
indicator shows yellow and the purge timing proceeds. At
the end of the purge time the purge flow is switched off and
only a small air flow is used to compensate for any leaks in
the enclosure. This keeps the pressure inside the
enclosure slightly higher than the outside pressure,
preventing flammable gas entering the enclosure. Whilst
this safe condition is maintained the system output enables
power to be applied to the equipment, either directly or via
a separate interface unit.
For dust applications [Ex pD] see certificate for "conditions
for safe use".
Features
One Model number: includes the
Control Unit (CU) and Relief Valve (RLV).
Direct Mount: no interconnecting pipe
work. Reduced material and labor cost.
Size: Compact Control Unit and Relief
Valve (No real-estate wastage around
the purged enclosure).
316L Stainless steel housings and
fittings for use in harsh environments.
Purge Flow: measured at the Relief
Valve, outlet. Gives full compliance
with standards. See IEC / EN 60079-2,
NFPA 496 Chapter 3-4. "have
passed through the purge enclosure".
Multiple enclosures may be purged in
series.
Independent of supply voltage.
Global approvals so ideal for the OEM.
