High-performance cooling fans for electronic systems

09-07-2025 | Inelcohunter | Industrial

Inelco Hunter now offers the DiaForce range of cooling fans from EBM-Papst. Designed specifically for cooling electronic systems, their high performance means that a single fan can replace two conventional fans.

Systems that process vast amounts of data are becoming increasingly powerful, and cooling is becoming a considerable challenge in various industries, including telecommunications and automation. To increase cooling capacity, two axial fans are often connected in series, usually with counter-rotating blades. This double-fan layout increases the pressure, but also results in higher noise levels. These fans can be used as an alternative to twin conventional axial fans.

The secret of the DiaForce lies in the combination of a high-performance motor with a unique impeller and housing geometries. The innovative design of the components for the flow machine minimises the main vortices that cause noise. This ensures a notable noise reduction, and it also increases pressure and efficiency.

One particular advantage in terms of aerodynamics is that the DiaForce offers an air performance curve with no dip. The high maximum cooling capacity is often not required in normal operation because these fans are frequently used in partial-load operation. However, a sufficient power reserve is crucial to ensure that the cooling system delivers adequate cooling and continues to function sufficiently under conditions outside the normal operational range.

In addition to the DiaForce 120, two further sizes – 40mm and 80mm – are now also available. The compact DiaForce 80 excels in applications such as server trays and high-performance power supply units with high performance and pleasant noise characteristics. The DiaForce 40 is a smaller addition to the product range, benefiting routers, switches, network technology, industrial automation, control systems, and robotics.

In addition to offering fans as standard boxed products, the company provides a High-Level Assembly (HLA) service to assist customers with customisation and adaptation. The HLA service involves integrating various components into larger assemblies, often PCBs within enclosures, and potentially including testing and full customisation. The company's HLA service enables the creation of fully functional, turnkey systems, and its in-depth engineering support ensures rapid implementation, thereby accelerating the customer's time-to-market.
