Bunded Tanks

To understand tank bund alarms, you first need to know about bunded tanks. Bunded tanks are double-skinned and can be thought of as a tank within a tank. They offer double the protection of traditional single-skinned tanks.

Bunded tanks are already mandatory for new tank sales across Europe and, to ensure safety of people and the local environment, it is compulsory that these tanks are fitted with bund alarms.
