The leak detection systems that we supply and install are all manufactured to the highest quality and monitor both double-walled pipework and fuel storage tanks with vacuum leak detection systems or pressure leak detection systems that adhere to the highest environmental protection levels in accordance with EN 13160.

Our leak detection systems consist of leak detectors and leak indicators that monitor fuel storage tanks and dual contained fuel lines continuously for all leaks. Leak detection systems for fuel storage tanks or leak detectors for fuel lines work on overpressure or under pressure and may be supported by a leakage sensor or a leak probe.

Millions of fuel storage tanks and dual contained pipework systems are monitored by leak detection systems that ensure the protection of our environment. As the leak indication is given by a leak indicator before the stored liquid can enter the environment, these systems are also well known as leak prevention systems.

LAD-R Double Skin Pipe Leak Detector – Pressurised

Leak Detection SystemsThe LAD-R pressure type leak detector contains the following elements in an impact-resistant housing display elements and controls, a printed circuit board with the electronic components for processing the output signal and connections for the remote pressure gauge with two switching contacts or individual high and low-pressure switches as required.

The LAD-R monitors the over/under pressure in the interstitial space of a pipe or storage tank and generates an alarm signal in the case of a pressure drop or increase.

The alarm is indicated audibly and visibly and is also available via a voltage-free relay contact (1 changeover contact). The switch points for low and high pressure can be adjusted via the two switching contacts of the remote pressure gauge by means of an adjustable spanner. The total monitored interstitial space volume must not exceed 1200 litres per LAD-R.

Constructed of aluminium, the manifolds are available with 1 to 6 connections and fitted with a 1, 5 or 10 bar pressure gauge according to requirements. Connections are designed for 6mm plastic or copper pipes.

Supplied with one way manifold as standard.

**Please note that the LAD-R is built to order – Delivery time is typically 10-14 days from when order is placed**

ASF Leak Detector Type D29 – Pressure Principle


  • The leak detector is used to monitor non-pressurized underground/aboveground double-walled pipelines.
  • For monitoring of water-polluting liquids, and flammable liquids having a flashpoint of < 55°C.
  • The interstitial space of the double-walled pipeline must be suited for the connection and operation of this leak detector.
  • The leak detector can be used for monitoring several underground pipelines utilizing a manifold.

The leak detector must be mounted outside the hazardous area (ex-zone).

Leak Detection SystemsOperating Conditions

  • The double-walled pipelines must be depressurized.
  • Leak detection fluid may not be present in the interstitial space of the container.
  • Appropriate manifolds together with a D29 leak detector may only be used for monitoring underground pipelines.


  • Installation of a potential free relay.
  • Installation in the protective casing with exterior alarm and heating.
  • Mounting kits for connection to pipelines and manifolds.

SGB Leak Detection Systems

Market Leading SGB Leak Detection

SGB leak detection is the market-leading brand, ensuring quality in monitoring double-walled pipework and tanks with a vacuum leak detector or a pressure leak detector to realise the highest environmental protection level in accordance with EN 13160.

An SGB leak detection system consists of a leak detector and a leak indicator, which monitors tanks and pipes 100% of the time continuously for any leak. SGB leak detectors for tanks or leak detectors for pipes are either working on over-pressure or under-pressure and also might be supported by a leakage sensor or a leak probe. Millions of tanks and pipe systems are monitored by a leak detection system to ensure protection of our environment. As the leak indication is given by an leak indicator before stored liquid can enter the environment these systems are also well known as a leak prevention system.
