DOPA: tank transformation and double- floor

Wolftank's more than 25 years’ experience in refurbishing tanks has led to the creation of the unique technology DOPA® single wall to double wall transformation system, that can be used for non-pressurized (atmospheric) underground tanks used to store potentially hazardous liquids, such as automotive fuels or chemicals.


The DOPA® system improves contamination protection by continuous vacuum monitoring of the interstitial space. The technology permits the transformation of the entire inner surface or just the ceation of a second floor of a flat bottom tank, so that there is no need to replace the tank. The interstitial space is created on the bottom of vertical tanks to ensure integrity of the double bottom. This allows the system to achieve the highest standards of environmental safety (EN13160 class 1).
The DOPA® remote monitoring system works with Wolftank leak detectors, which provide automated and continuous 24/7 monitoring, so that the device may not be deactivated without causing an alarm to sound.


Wolftank presents DUPLO, to transform an oil/chemical tank into a double wall tank, and add a class 1 leak detection system, thus offering complete and continuous 24/7 protection of the facility.
DUPLO maintains the functionality of the system increasing its value
The DUPLO solution is technically equivalent to a second steel bottom for an above ground tank or to the replacement of an underground tank characterized by a significantly easier application process.
The class 1 leak detection system according to EN 13160 cannot by bypassed nor tampered with, and generates an alert if one of the two walls is compromised or the device has been tampered with or switched off.
The technology is successfully applied to both underground and aboveground tanks and to any storage facility being monitored under current regulations.
