Whichever way you turn it: It's the benchmark.
The new RadiPac

Impossible? Not any more!

The requirements for ventilation and air conditioning devices are constantly increasing, especially when it comes to energy efficiency. This is due to increasingly strict legal requirements, as well as the growing environmental awareness of users and the possibility of saving energy costs. The fans also need to be as quiet as possible, intelligent, and straightforward at the same time.

All of this poses major challenges for engineers. After all, every improvement in one area always means a compromise somewhere else. Can there be a fan that impresses in all areas?

ebm-papst provides the answer with the new RadiPac: Not only is it much more powerful than its predecessors, it is also especially energy-efficient, quiet, compact and intelligent. Simply benchmark, whichever way you turn it.

Your benefits

  • Sizes 310 to 630 s a motor-impeller combination and ready-to-install plug & play support bracket
  • Air flow up to 20,000 m³/h and pressures over 2,000 Pa
  • Temperature range from -25 °C to +40 °C
  • GreenTech EC motors from 500 W to 8 kW and a configurable control interface for analogue and digital signals
  • All versions are also available as a compact short version

The newly developed impeller plays an important role in increasing efficiency. A high-strength, glass-fibre reinforced composite material was used, enabling the complex shape of the five spatially twisted and strength-optimised 3D blades. Thanks to the rounded flow contour and the tapering profile of the blade outlet, flow losses have been drastically reduced and noise characteristics optimised.

In addition, the corrugated cover plate ensures the best possible filling level and thus considerable air flows of up to 20,000 m3/h. The sturdy material also enables high speeds and therefore pressures of more than 2,000 Pa – over the entire temperature range.

The driving force behind the new RadiPac centrifugal fans are high-efficiency GreenTech EC motors in the power range from 500 W to 8 kW. The integrated EC motors with external rotor design achieve efficiency levels in accordance with the requirements for efficiency class IE5 set out in IEC/TS 60034-30-2. On top of this, they don't need any rare earths and are also impressively compact thanks to the typical ebm‑papst external rotor design.

AHUs are also getting smarter and smarter. Digital networking of the fans with their surroundings is a prerequisite for intelligent additional functions and flexible control options. The high-performance electronics provide everything required for this, such as a configurable control interface for analogue and digital signals that can be individually adapted, as well as a serial MODBUS RTU interface. This enables operating data such as speed, power consumption or operating time to be read out and processed digitally, for example.

For the first time, an important intelligent feature of the new RadiPac is included as standard: automatic resonance detection. The integrated vibration sensor measures mechanical vibrations and detects resonance points within the speed range. During initial commissioning, these vibrations are recorded and simply “run over” in normal operation later. This prevents premature bearing damage and thus system failures while increasing the fan's service life.

Versions and accessories

In order to suit every installation situation, the new RadiPac is available in various designs – the choice is yours:

 

In the standard version, the most powerful motor is completely pulled out of the flow area. In the short version, the motor is immersed in the impeller. This makes the fans more compact but with a slightly lower pressure increase. However, they still offer a significant increase in performance compared with previous models. 

 

Both RadiPac versions are available as a motor-impeller combination or as a ready-to-install plug & play solution in a compact support bracket. The support plates are dimensioned to make the best possible use of space on a Euro pallet. This saves transport costs and improves the CO2 footprint.

 

The fans are also available with the FlowGrid air inlet grille, which works like a rectifier and reduces noise-generating turbulence in the inflow. The air performance and power consumption remain unchanged. In the completely enclosed version, the FlowGrid is also used as a guard grill.

Higher air flow

The success story continues.

ebm-papst has been continuously and consistently developing the RadiPac product range for many years – in terms of aerodynamics, motor technology and electronics. This made it possible to achieve another milestone with the latest generation – in terms of efficiency, noise characteristics and intelligence.

“Healthy air thanks to FanGrid”

 

When a huge axial fan broke down in the Skaraborg clinic in Sweden, the air conditioner could no longer produce the required air flow. But replacing the unit would have required modifications. It was time for a forward-thinking solution.
