Properly-sized Enardo 2000 and Enardo 2500 Series

meet the API standard 2000 for emergency venting due to

fire exposure. Enardo 2500 Series handles high capacity

vacuum flow 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.
