Saddle tanks

Tunetanken saddle tanks are fully moulded in fiber-reinforced composite material and are thus an optimal solution for storage of liquid media. Along with the strong composite material, the design secures a sealed and leakproof tank that is resistant towards corrosion, tearing and climatic influences.

Tunetanken saddle tanks are, therefore, well-suited for a range of different purposes such as storage of corrosive media e.g., acids/bases, saline solutions, process water, flocculating agents for wastewater cleaning or chemicals. Our saddle tanks are approved for contact with food in accordance to regulations applied by Danish Ministry of Environment and Food as well as are recognised by the Danish Smiley Identification system.

Tunetanken saddle tanks are built with saddles in order to secure the necessary stability in relation to size and foundation. This means that our saddle tanks are reliable all year round no matter the location as well as provide security for your daily work. Fully moulded design and smooth surfaces ensure that the emptying process is efficient as well as facilitate the cleaning.

With almost five decades of experience working with composite materials, together with the latest developments within the subject, we are your quality supplier when it comes to saddle tanks. We think of design and functionality when we produce your tank. This way, we make sure that your storage tank is also an investment into your future.
