Reference: BUNDGUARD®
This preventive solution for risks related to oil spills is specifically designed for retention bunds located under electrical transformers.
It ensures constant monitoring of water levels and the presence of oil. It is particularly used to optimize maintenance operations and increase lifetime of filtres FILTRELEC®.
This compact system is fully automatic and provides efficient management of environmental risks.


The BUNDGUARD system consists of two main components: an electrical control box and a detection unit.
The detection unit monitors the fluid level in the bund in real-time and triggers high-level and hydrocarbon presence alarms.
The electrical control box is equipped with local indicators that allow easy visualization of the system status (visual alarms) such as remote interfacing with various control systems.
The BUNDGUARD monitoring system combined with the FILTRELEC® F50 mobile depollution system makes the depollution device autonomous and automatic. Additionally, this combination enhances its robustness by preventing the influx of concentrated oil into the filter.
In addition, in a bund or containment basin equipped with FILTRELEC® rainwater filters, the BUNDGUARD monitoring system alerts maintenance teams in case of filters saturation.
The quality of the equipment is systematically checked and recorded. Each BUNDGUARD is tested in the factory before shipment.
