Axial fan airfoil high efficiency

Mobile applications

Forage harvester KRONE BiG X 1100

Mobile application is a broad term covering construction, forestry, mining and equivalent machinery.

Each machine is unique and has specific capabilities. Our strength is our ability to support our customers in identifying the fan solution which reinforces this uniqueness.

One of our core competences is to fully document our fans not only in terms of performance, but also in terms of strength. Detailed information on durability, natural frequencies, and data on deflection during operation can be provided by our experienced Sales Engineers.

Mobile applications generally call for robust axial fan designs. The combination of axial fan blades cast in glass reinforced polyamide PAG and hub parts cast in aluminium alloy AL means less wear on engines and bearings. This material combination offers an axial fan with high durability able to cope with the vibrations generated by machinery. In situations with extreme vibration levels the variant PAGST may prove to be the best option. All versions of PAG enable operating temperatures as high as 120°C.

Our axial fans are designed to comply with TIER IV regulations in the USA and the Stage IIIB regulations in the EU. The PressureMAX axial fan blade is specifically designed for these regulations, generating maximum pressure at high efficiencies.

Fan blade profiles suitable for mobile applications are typically our high efficiency airfoil fan blades within the H and Z series. Depending on the size of the required unit we offer: 2H, 3H, 3Z, 4Z & 5Z blades. When noise emission is a key success criteria we also offer fan blades from our sickle series such as 1H, 4H, 1Z, 2Z and 7Z.

For larger radiator applications we offer fan blades from our W series covering diameters from 550mm to 2140mm. The W series offers both airfoil and sickle type fan blades 1W, 2W, 3W, 5W, 6W, 7W, & 9W.

In situations with very restricted inlet conditions,our increasing arc type fan blades 6H and 6Z offer high performing solutions.

Radiator manufacturers

Designing fans for radiator packages is one of our core competencies. It is a major part of our business and we have excelled in selecting suitable fans for more than 55 years.

Engine manufacturers

The vibration level is typically relative high as the axial fans are often mounted directly on to the crankshaft of the engine, hence it is important that the axial fan is as light weighted as possible.

Wind turbines

This sub segment is very similar to the radiator manufacturing. However, as the wind turbines are often erected as off-shore installations the level of the demands are higher.
