Maximize Protection of Secondary Containment

The Veeder-Root Secondary Containment Sensing System was designed to meet several regulatory requirements that require a vacuum on secondary containment system. This technology can be used across multiple platforms such as, retail, marina’s, commercial and industrial applications.

The Secondary Containment Vacuum Sensing System (SCVS) detects even the smallest leaks, preventing them from entering the environment — costing you money on repairs. Using installed submersible turbine pumps (STPs), a vacuum seal is created, which closes the interstitial spaces of your tanks, piping, sumps, and pans. Only available for new constructions sites.

Maximize Protection of Secondary Containment

Key Benefits

Maximized protection with a vacuum-monitored secondary containment system
Reduces exposure to risk by sending an alarm to your tank gauge when vacuum seal cannot be maintained
System alarms you when liquid is detected in secondary space
Facilitates periodic operability testing and simple to install

Certified for Use

Certified to meet California's requirement for secondary space monitoring for tanks and lines as required by AB 2481
Satisfies the requirements for Class I Leak Detection as defined by the European Standard EN 13160-2
3rd Party, National Work Group and LG113 listed

Operating Temperature Rating: -25 degrees C to +70 degrees C

The Vacuum Sensor is compatible with the following consoles:

TLS-450PLUS ATG*
TLS-350R ATG w/BIR**
TLS-350PLUS ATG**
TLS-350 ATG

*Supported with Version 9.A and higher software

**Upgrade Note: The Vacuum Sensor System requires the console to have version 24C software (or greater) along with an ECPU2 or ECPU w/ NVMEM 1 board.

Key Features

Vacuum Alarm: Alarms when vacuum cannot be maintained or when replenish rate exceeds 85 liters per hour – prevents leak from entering environment, reducing site’s exposure to costly repairs
Liquid Alarm: Alarms when liquid is detected in the secondary space – early notification of leak allows users to react and fix the potential issue before it reaches the environment
Simple Installation: Installs in STP sump and connects to the console through intrinsically safe wiring
Operability Testing: Facilitates periodic tests leveraging existing Veeder-Root systems
