Digestion towers & silos

Flexibility and precision

for digestion towers

For digestion towers Digestion towers are essential components of modern wastewater and biogas plants. They pose particular challenges for architects and engineers, as they must not only be technically sophisticated, but also durable and flexible in design. New buildings require precise planning and implementation, while renovations demand a high degree of adaptability to existing structures. With its free-form roof and façade systems, Kalzip offers the ideal solution to meet these requirements – with flexible structures that adapt perfectly to the complex geometries of digestion towers.

Functional and architectural

System solutions for silos and digestion towers

Silos and digestion towers are highly specialised structures in industrial and utility infrastructure. They must absorb enormous static loads, withstand weather conditions for decades and, at the same time, meet increasing demands for sustainability and cost-effectiveness. In addition to pure functionality, a precise and durable building envelope also plays a decisive role.

Kalzip roof and façade systems offer tailor-made solutions for this purpose. With conical standing seam profiles, special installation concepts and robust aluminium surfaces, even large round structures can be permanently protected. The systems combine technical precision with flexibility in design and create durable solutions for infrastructure buildings subject to high loads.

Kalzip systems are the ideal choice for digestion towers because they:

  • Combining flexibility and precision: our free-form systems enable complex geometries and customised designs for roofs and façades to be realised.
  • Guaranteed durability and robustness: Kalzip products are resistant to aggressive environmental conditions and offer a long service life – ideal for digestion towers.
  • Offering adaptability for renovations: Thanks to flexible roof structures, existing structures can be efficiently modernised and adapted to current requirements.
  • Combining aesthetics and functionality: our systems combine technical precision with a modern look that blends harmoniously into industrial environments.

Mit Kalzip gestalten Architekten und Ingenieure Faultürme, die sowohl technisch als auch visuell überzeugen und den Anforderungen moderner Abwasser- und Biogasanlagen gerecht werden.

FREE FORM SYSTEMS

WHY THE KALZIP FLEXICON FREE-FORM ROOF SYSTEM OFFERS MAXIMUM FLEXIBILITY IN PLANNING AND ARCHITECTURAL ELEGANCE

The Kalzip FlexiCon free-form roof system offers a technically sophisticated, precisely fitting and weatherproof solution for silos and digestion towers. The modular aluminium substructure allows precise adaptation to curved tower shapes and ensures reliable installation.

  • Large height differences can be compensated – ideal for curved and cylindrical silo tops
  • Three measuring points enable precise adjustment – ensuring permanent tightness under façade loads
  • XT free-form profiles adapt to organic contours – perfect for round and sloping towers
  • Economical substructure – reduces costs even with complex roof geometries
  • Durable, corrosion-resistant aluminium alloy – low maintenance in aggressive emissions
  • Complete engineering and project-related manufacturing – planning reliability and on-time implementation


The FlexiCon system offers maximum shape adaptation, a flat surface and the highest technical precision for silos/digestion towers – ideal for efficient and safe container roofing.

Kalzip freeform system

Colours, materials and surfaces:
Silos and digestion towers are striking structures in industrial and utility infrastructure. Kalzip offers a wide variety of surfaces and coatings – from natural aluminium to AluPlusPatina and metallic finishes. This gives even highly functional structures an architectural quality with a clear visual impact from a distance.

Product highlight for silos and digestion towers:

  • Free-form systems – enable precise and secure roofing of round and conical structures, even at great heights and with unusual geometries.

Combinability:
The free-form system can be combined with functional components such as maintenance openings or light wells. This results in durable building envelopes that combine robustness and flexibility.

Sustainability as a design feature:
Through the use of recyclable aluminium and energy-efficient structures, silos and digestion towers make a visible contribution to sustainable infrastructure.

Architectural trends:
In addition to pure functionality, visual appeal is also becoming increasingly important. Metallic surfaces and precise shaping give silos and digestion towers an architectural presence that highlights their technical capabilities.

This diversity gives rise to infrastructure buildings that combine maximum functionality with a durable and architecturally striking building envelope.

FAQ

What are the challenges involved in planning digestion towers?

Digestion towers require precise planning in order to meet complex geometrical and technical requirements such as stability, durability and protection against aggressive environmental conditions.

How can existing digestion towers be efficiently refurbished?

When renovating, it is important to use flexible solutions that can be adapted to existing structures while improving the functionality and service life of the digestion tower.

What requirements must materials for digestion towers meet?

Materials for digestion towers should be corrosion-resistant, durable and low-maintenance in order to withstand the particular stresses caused by moisture and chemical influences.
