The UPP leak detection system monitors the interstitial space that runs the entire length of any UPP secondary contained pipework.
Using pressurised air or nitrogen, the system monitors the pressure within the interstitial space. Any reduction in pressure indicates a leak has occurred either in the primary or secondary pipe and a visual alarm is shown on the system’s display screen. An optional external audible alarm will sound allowing the site operator to take the relevant pipelines out of service.

A pump housed inside the unit maintains the pressure in the system, meaning no external pressurised air or gas cylinders are required, reducing running costs for the operator.

It is possible to connect one unit to several double wall pipe lines on a site using manifolds (with individual line gauges for easy identification of leaking lines) or using interconnecting tubing.

Both LD-UPP-3 and LD-UPP-2 leak detectors comply with EN13160 and fulfil the highest environmental protection level.
