Product Description
Emergency pressure relief vents are designed to
provide an emergency pressure relief opening for
storage tanks when exposed to overpressures that are
not handled by standard tank vents.
2000 Series emergency pressure relief vent (EPRV)
provides pressure relief only. 2500 Series emergency
pressure relief vent with vacuum (EPRV-V) provides
pressure and vacuum relief.
Properly-sized 2000 and 2500 Series meet the API
standard 2000 for emergency venting due to re
exposure. 2500 Series handles high capacity vacuum
ow for emergency pump-out of product. These
vents provide quick easy access for tank inspection
and maintenance.
Remote Monitoring Option
The Smart Wireless monitoring option is available with
the Enardo 2000 Series. It allows the detection of the
Open or Closed position of the emergency vent from a
remote site. Under normal conditions, the emergency
vent should be Closed. An Open indication can alert
personnel that there is a potential safety or emissions
issue that should be further investigated.
