Aluminum combi tanks for machinery, equipment and vehicle technology

Aluminum combi tanks usually consist of two chambers. The chambers are used to separate different fuels or liquids. For example, combi tanks are used for the removal and storage of diesel and hydraulic oil in machines, plants and vehicle technology (vehicles). This combination in one tank unit is particularly suitable for tight spaces.

In addition to the legal requirements, aluminum combination tanks have to meet a large number of other requirements. Constant mechanical stresses, vibrations and temperature fluctuations present aluminum combi tanks with particular challenges in daily use. Added to this are the demands placed on strength by complicated designs for maximum filling volume.

We only produce individual solutions for orders of at least 50 pieces

Manufacturing process

Manual welding
As a welding company, we work with qualified personnel and draw on our many years of experience in welding technology. We work with the automated welding process and also manufacture hand-welded aluminum combination tanks. The manual welding process is recommended as a cost-effective, time-saving choice for one-off productions as well as small and medium-sized series. Hand-welded aluminum combination tanks are produced on current welding tables.  Our own fixture construction ensures dimensional accuracy. Repeatability can also be permanently met even with high tolerances.

Automated welding
The automated welding process is implemented by our state-of-the-art welding robots. Automated production is very fast and efficient. This pays off especially for high requirements that are to be produced cost-effectively with consistent quality at all times. The automated welding process offers the highest possible precision. This means that even very complex aluminum combi tanks with high tolerance requirements can be welded.

Manufacturing process

Corrosion protection and finishes for aluminum combi tanks

Surface treatments perfect durability, safety and appearance. A long-term corrosion-free, protected and stable surface promotes the durability of aluminum combination tanks. Surface finishes also give aluminum combination tanks a more pleasing appearance. With our own powder coating and painting facility, surfaces in all RAL colors can be finished quickly and to a high standard. For effective corrosion protection, we apply heat-resistant paints, powder coatings as well as pickling and passivation.

We examine the structural strength, fatigue strength and material efficiency of your design, among other things, already in the initial development phases with the help of FEM calculations. This gives you peace of mind during the test phases and also after your product has been put into operation by your customers. In doing so, we digitally illustrate the consequences of different mechanical, thermal and electrical impacts through linear and non-linear structural-mechanical modeling. This allows us to estimate the effects of the various loads on the entire product or component for any more or less complex geometry before we build prototypes.

The results of these considerations are also available as evidence for technical approvals, for product liability and production releases.

NovaNox® performs FEM calculations analytically based on general and international standards. This ensures comparability and reliable results. In detail we do for you

  • linear and non-linear structural mechanics calculations
  • Analysis of deformations, stiffnesses and stability
  • Consideration of natural vibrations
  • Transient structural analysis
  • Collision analyses
  • Temperature field calculation (thermal-stationary or thermal-transient)
  • CAE-supported fatigue analysis with nCode

You will receive technical drawings from us in 2D (in dxf, dwg and pdf formats) and in 3D (in step format). Depending on your needs, you will receive from us single part drawings, assembly drawings, general drawings or assembly drawings. In addition, you will receive detailed technical documentation for revision. This gives you the chance to adjust or add details before production. Then, when the production line starts rolling, you can be sure that everything will fit perfectly and be implemented without errors.

With our comprehensive technical drawings and detailed documentation, you achieve precise communication and greater efficiency throughout your entire development and manufacturing process chain. Each process stage receives the information it needs.

In order to produce a product that is as close to real life as possible, even at the prototype stage, we work seamlessly with you on the development, planning and design of the construction, the material and the manufacturing process. This ensures the best possible results and adherence to your schedule and budget.

Finally, we analyze the results of the FAI and fine-tune the manufacturing process for maximum efficiency and cost-effectiveness. In doing so, we help to noticeably reduce implementation times and successfully go into series production as planned. This preserves your project budget and provides additional security.

We take the entire process of component supply off your shoulders. We take care of all processes for you, from requirements planning to logistics. This includes our consignment warehouse to ensure your uninterrupted production processes with a total of 1,200 square meters of storage space. You save costs compared to your own storage capacities. And you can produce in larger batches more cost-effectively.

Your best possible component supply for series production is thus assured. We deliver your aluminum combi tanks from the consignment warehouse on time and according to your requirements. Your existing logistics processes are integrally taken into account. Thus you create the most convenient solution for a secure component supply with aluminum combi tanks from NovaNox® for the whole year.
