Leak detectors for a clean and protected environment

WE PROTECT WHAT YOU DRINK

Creating double-walled tanks, pipes and collecting chambers that are safe to humans and the environment – that’s what we aim to achieve with our leak detectors and leak detection probes. SGB leak detectors monitor any type of double-walled tank and pipe for leaks. From small to major leaks – our leak detection systems raise an alarm before environmental or water pollution can occur!

Our varied product portfolio provides a secure technical and cost-effective solution for your application case:

• Leak detection systems for double-walled tanks/pipes
• Leak detectors for single-walled tanks with leak protection lining/jacket
• Leak detection systems for explosive areas/applications
• Leak detection probes for collecting chambers, access chambers, sumps
• Accessories and spare parts

All of our leak detection systems work on the pneumatic principle (pressure/vacuum). Air or gas is applied in the interstitial space (gap between the inner and outer wall) and monitored with a leak detector. If there is a leak, the pressure in the interstitial space drops and an alarm is triggered. This functional principle complies with Class I of the European standard EN 13160 – the highest leak monitoring standard.

• The inner and outer walls are fully and permanently monitored for leaks.
• No stored product can be spilled into the environment.

Terms

Brief and to the point in alphabetical order

Flat-bottomed tank
has a double floor or floor lining. The gap is suitable as an interstitial space.

Interstitial space
Gap between the inner and outer wall. Air, water and stored product must be able to pass through and the stability must be sufficient for any overpressure or vacuums.

Leak detectors/leak alarms
are comprised of electrical, electronic and pneumatic components and regulate/monitor a specified operating pressure in the leak detection system. They warn of impermissible pressure changes (leaks) with a visual and audible alarm, if necessary also with additional sensors in the suction line to the leak detector.

Leak detection systems
are comprised of leak detectors, connection lines, interstitial space, leak detection medium

Leak protection lining
is comprised of flexible or rigid tank liner, intermediate layer, fixing devices, suction and measuring line connections, a suction line for the leak detector to the tank floor, if necessary

Pipe, double-walled
has an inner and outer wall. The gap is suitable as an interstitial space.

Pressure leak detectors
trigger the alarm if the pressure drops below the permissible limit.

Tank, double-walled
has a second wall (at least up to the height of the permissible filling level). The gap is suitable as an interstitial space.

Tank, single-walled, with leak protection lining
has a lining inside the tank (at least up to the height of the permissible filling level). The gap is suitable as an interstitial space.

Tank, single-walled, with leak protecting jacket
has a jacket around the container (at least up to the height of the permissible filling level). The gap is suitable as an interstitial space.

Vacuum leak detectors
trigger the alarm in the event of impermissible pressure increases.
