Diesel tanks: a specialism of Pentas Moulding

The rotational moulding process is perfectly suited for the production of tanks. After all, every tank is hollow and that is a property that is created automatically by rotational moulding. Pentas Moulding specialises in the rotational moulding of tanks for CLAAS, among others. Innovation, efficiency and safety are always paramount.


The combustion engine remains

Despite the unstoppable rise of electric vehicles and other green fuels such as hydrogen, the internal combustion engine will continue to play an important role in certain areas of application in the coming years.

For example, think of land-based machines, tractors, self-propelled forage harvesters and combines. Heavy machines that do mountains of work in a short period of time, driven by the ever-increasingly unpredictable weather conditions. They need an enormous amount of energy to do that, energy supplied by the fuel in the tank.

The internal combustion engine is also developing. Biodiesel has long since ceased to be a buzzword and there are now various compositions. In addition, the addition of Ad-Blue ensures that the emission of particulate matter is kept to a minimum.


Higher capacity, higher safety

The increasingly intense weather in Western Europe and the increase in scale in agriculture require machines with an ever-increasing capacity. It must also be possible to work a long day without interruptions. In other words: you want to carry as much diesel as possible.

By opting for rotational moulding, there is a high degree of design freedom. At Pentas Moulding, we can fill every hole in the machine by using a tank. Give us the drawing of the bodywork and we will get started to use the space as efficiently as possible.

Naturally, the safety of fuel tanks is also subject to ever-increasing demands. We ensure that a TÜV certificate is issued and that each tank is 100% leak-proof tested.


Weight saving through rotational moulding

As is often the case in life, the interests are conflicting. The ever-heavier machines compact the soil and thereby put pressure on soil life. This is a bad development for agricultural land because the yield decreases year after year as a result.

By using plastic to achieve weight savings, you are already taking a step that can generate enormous profits. In collaboration with harvester manufacturer CLAAS, Pentas Moulding added to that.

We use the Finite Element Method (FEM) computer simulation to calculate peak loads, in order to be able to conclude whether the product is ‘fit for use’. We use this technique to save weight. Less weight in rotational moulding means a lower filling weight and inherently lower wall thickness.

According to the FEM simulation, lower wall thickness is possible in 90% of the tank surface. The key question remains how to deal with the 10% where the tax is too high. Pentas Moulding can solve this issue for you. By developing a rib structure based on the simulation, the above 10% is provided with a higher wall thickness to cope with peak loads. In other words: only extra weight, where necessary.

A saving of ± 35% has been achieved on a tank with a capacity of ± 1000 L. This is one of the reasons why we have become ‘Supplier of the Year 2018‘ of CLAAS.

This innovative strength once again underlines the specialisation in this branch of sport.

In addition to diesel tanks, we are also happy to produce your Ad-Blue Tanks, water tanks, oil tanks and/or hydraulic tanks in plastic. We are also ready for your battery housing in plastic.
