Double-walled tanks (for heating oil, fuels and hazardous substances)

Above-ground and underground double-walled non-pressure and low-pressure tanks for storing heating oil, fuels, and flammable, toxic and corrosive substances form one of the key product groups in our offer.

We manufacture low-pressure tanks rated up to 0.5 bar and non-pressure tanks subject to UDT oversight. The double-walled design (tank within a tank) acts as an integrated containment bund — should the inner wall develop a leak, the outer wall retains the medium, completely eliminating any risk of spillage into the ground and environmental contamination.

As standard, our tanks are equipped with a leak monitoring system (interstitial sensor with alarm unit) and overfill protection. The tanks comply with current legal standards and UDT requirements.

We offer full flexibility in choosing the installation location:

Above-ground tanks — ideal for installation indoors (boiler room, industrial hall) or outside a building. The location provides easy access for operation and servicing.

Underground tanks — for customers who value aesthetics and space efficiency on their property. They feature additional anti-corrosion protection and a reinforced structure designed to withstand soil loads.

Below is our standard product range. We also manufacture tanks in intermediate sizes — depending on customer requirements.
