Mannloser Einbau / Montagesysteme



As an innovative company, FENOTEC GmbH is constantly on the lookout for new ways to make installation easier for tank protection specialists. Methods such as flanging through the ceiling and innovations such as the patented ready-made fleece for cellar tanks and the sewn fleece for cylindrical tanks simplify the installation of the leak protection lining considerably and accelerate the assembly.

Installation also possible without getting into the tank!

With our patented system of unmanned installation, the installation of a leak protection lining is also possible without entering the tank. Due to the increased risk of serious to fatal accidents during tank assembly, the major oil companies have started to prohibit tank access. On the basis of this requirement, fenotec GmbH developed a system for the unmanned installation of leak protection linings at the instigation of Shell and with the support of Tokheim Service GmbH & Co. KG.

The solution with a flexible installation chute made of foil, with the help of which the leak protection lining is pulled into the tank, is used both for the repair of defective and the preventive protection of older tanks.
This development guarantees that tanks will be refurbished to the highest safety and quality standards and that a double-walled tank will also be built at locations that are difficult to access.
The fact that all components are optimally prepared for assembly at the factory means that installation can be carried out very quickly. A precise description of the procedure and the prefabricated components reduce the probability of errors during assembly to a minimum. The final control over a vacuum makes it possible to check exactly whether the installation was successful and can withstand the requirements of operating a tank at a filling station over the years.

Sewn fleece for cellar tanks: the original – patented and proven a thousand times over

The prefabricated wall, floor and ceiling tracks are delivered in individual rolls. This guarantees an easy insertion of the intermediate layer even with small ceiling distances. After the wall track is clamped between floor and ceiling, the floor track is rolled out like a carpet. As soon as the cover is aligned, the fleece is rolled out on the cover. The fixation of the ceiling fleece is achieved with the dome neck and a Velcro strip on the cover. Inflate, set clamping ring… done!

Stitched fleece for cylindrical tanks: don’t do things by halves – take the original

Another solution that we have developed for our customers is the sewn fleece for cylindrical tanks. The intermediate layer is made like a second skin for the inner shell of the tank and inflated together with the inner shell in the tank.
There’s no faster way to get a tank fixed – guaranteed!

Flanging through the ceiling – a proven solution for 25 years

With the use of the flange system, the extension of the existing filling and ventilation lines or the installation of an additional dome cover can be dispensed with in many cellar tanks manufactured at the site. This considerably reduces assembly times.
