BundGuard® protects your site 24 hours a day, 7 days a week, 365 days a year

Market-leading BundGuard® is a cost-effective, self-contained and easy-to-fit automatic submersible pump and alarm unit that is installed in a sump, within a bund and works continuously and automatically 24 hours a day, 7 days a week, 365 days a year.

BundGuard® is designed to be used in conjunction with an on-site drainage interceptor in order to maintain the 110% capacity within an oil storage bund. If there is no underground interceptor tank, Andel also supplies the FilterSepta®, a cost-effective above ground filter that will guarantee a Class 1 discharge of water from the bund to surface water adhereing to EN858-1:2002.

Over thirty thousand BundGuard® units are already protecting customer assets, site operators and the environment

The Andel BundGuard® system was first conceived and developed in 1992. A direct response to the UK electricity industry’s growing need for an effective solution for the serious water-removal problems at sub-station sites across the UK.

Since then over thirty thousand BundGuard® units have been installed both nationwide and overseas, protecting customer assets, site operators and the environment.

To be compliant with current UK regulations, all above-ground oil storage tanks that contain more than 200 litres of oil, must have secondary containment or a bund to contain oil leaks and spills. Most bunds are exposed to the elements and consequently are likely to collect and fill with rainwater. As a bund fills with water, the containment capacity is reduced and the risk of oil escaping by overtopping the bund wall in the event of tank failure is greatly increased. It is therefore essential that robust measures are put in place to extract rainwater from exposed bunds.

Andel BundGuard® 5

Through Andel’s policy of continual improvement, listening to customer feedback and advances in available technology, Andel launched BundGuard® 5.

BundGuard® 5 offers customers the option of a number of added features that provide enhanced control with advanced communications and functionality.

BundGuard® 5 has the capability to operate two pumps simultaneaously, as well as the option of using larger pumps where required and is equipped with advanced communications and display features.

BundGuard® expels water from the containment area

Using advanced circuitry and micro-controller technology, BundGuard® discriminates between oil and water, keeping oil contained and expelling water from the containment or bunded area.

The robust, submersible stainless steel sensor unit monitors the different liquid levels via a series of conductive probes. The control unit activates the pump as required to remove only clean water, safe to sewer or interceptor, depending on site circumstances. Failsafe systems and a range of visual and relay alarm outputs ensure complete safety and allow onward communication to remote monitoring systems.

BundGuard® not only gives total peace of mind and ensures compliance with regulations throughout the UK, it also removes the need for regular bund emptying by waste contractors, reducing costs, environmental impact and carbon footprint. In the absence of an on-site drainage interceptor tank, Andel recommends the FilterSepta®, a cost-effective, above-ground Class 1 interceptor and filter.

Andel has a team of experts that can adapt BundGuard® to deal with a variety of site conditions and special requirements:

• Semi ATEX units – sensors and pumps for zone 0 areas and control panels fitted in non-hazardous areas
• Units linked to pH sensors
• Units linked to Ammonia Sensors
• Units linked to detect unwanted contaminants in a site’s trade effluent
• Control units can be supplied in GRP enclosures to National Grid specifications
• Automatic sump frost protector systems for extreme weather conditions
• Adapted to include power coupling for portable generators

Special builds

Special-builds can be linked to sensors to detect unwanted contaminants in a site’s trade effluent, where if high levels are detected, the system will deactivate the pump so the contaminants are contained and do not reach the drainage system.

A bespoke system, using the National Grid specification control units in GRP enclosures was built to interface with the glycol system alarms, so that if the glycol system alarms trigger, a signal is sent to immediately disable the BundGuard® pump. The system also alerts the site to initiate a response.
