Suction system

Suction system

For monitoring tanks

For tanks at service stations pressure leak detectors offer the optimum benefit-cost ratio. Several tanks with a leak detector are cheaply and safely monitored:
DL 330 and
DL 330 FC with filter control for an even more reliable operation and
DL 330 ELC FC with integrated manifold, dryfilter control, wheaterproof housing and separate indicating unit.

For tanks with a test pressure ≤ 400 mbar
DL 230 for tanks with a diameter ≤ 2 m and
DL 280 for underground tanks with a diameter ≤ 2,5 m.

Due to technical reasons sometimes monitoring with overpressure is not possible, e. g. if the test pressure in the interstice is too low or if the system has been switched over from liquid leak detection. Then we recommend monitoring with explosion-proof vacuum leak detectors.

For monitoring pipes

Pipes at petrol stations with suction system (pump in the fuel dispenser) are monitored with an adequate explosion-protected underpressure leack detector. Thereby a sufficiently high alert-underpressure is of great importance.

As an alternative following overpressure leak detectors might be used:
DLR-P 2.0 + 4.5 petrol station
DLR-P .. CV plastic pipes

Combined solutions for monitoring tanks and pipes
Up to 12 tanks and 12 pipes are monitored continuously and safely by leak detection systems LDU14 and
VLXE-SAB T../P.. Both systems are made for outdoor installation. As a result, assembly costs can be reduced. In case of pressure/vacuum loss an alarm starts immediately before any product can pollute the environment. LDU14 and VLXE-SAB T../P.. conform class I of European standard EN 13160.
LDU14 => Leak monitoring with pressure for 1 to 12 tanks and/or pipes
VLXE-SAB T../P.. => Leak monitoring with vaccum for 12 tanks and/or pipes max.
