  • Infinitely variable speed control
  • Maximum air flow
  • Motor, electronics, and aerodynamics form a complete package

The advantages of the

EC medium pressure axial fans at a glance

Double flange housing

  • Low noise emissions thanks to integrated nozzle shape on intake side and minimal air gap due to perfect roundness
  • Integrated nozzle shape on intake side ensures high efficiency
  • Robust design with hot-dip galvanized sheet steel
  • Safe handling during transportation and assembly
  • Flexible arrangement with horizontal or vertical motor shaft and installation on both intake and outlet sides
  • Optional: Externally accessible terminal box with brought-out connections and interfaces

Impeller

  • High efficiency
  • Blade angle and number of blades ideally adapted to the motor and control electronics at the factory
  • Minimal vibration on account of dynamic two-plane balancing of the impeller-rotor unit
  • Robust design with blade and hub made of corrosion-resistant die-cast aluminum
  • Renowned blade geometry (airfoil)

GreenTech EC motor

  • Acoustically imperceptible clock frequency
  • Long service life thanks to maintenance-free ball bearings and brushless commutation
  • Optimized commutation for partial-load operation down to 1:10 with sustained high efficiency
  • Impeller fitted directly on the motor rotor for a compact design 
  • High efficiency level due to low copper and iron losses in the stator and no magnetization losses in the rotor through the use of permanent magnets
  • Insulated bearing system to prevent bearing currents ensures reliable operation

Electronics

  • Simple commissioning thanks to central terminal area for supply connection, alarm relay, open loop control and communication
  • Connection area physically separated from motor electronics
  • Infinitely variable speed, 0-10 VDC/PWM interface and MODBUS RTU
  • Different voltage configurations for worldwide use
  • Integrated derating function, locked-rotor protection and thermal overload protection for reliable operation

Motor mount

  • Robust design due to hot-dip galvanized welding 

Intake/outlet side guard grill (optional)

  • Contact protection according to standard DIN EN ISO 13857
  • Wide gap between guard grill and impeller
  • Robust hot-dip galvanized welded design

EC medium pressure axial fans: The efficient system solution

Infinitely economical

Adaptation of the air flow to actual requirements is a crucial factor with regard to the energy consumption of a system. With AC fans, this is often achieved by switching individual fans on and off. By contrast, GreenTech EC fans feature integrated, infinitely variable speed control enabling the air volume to be adjusted as needed. The power consumption Pe drops drastically (P~n³) on reducing the speed n.

The enormous potential for savings is illustrated by a simple calculation example: In nominal operation, an installation with four fans arranged in parallel has a power consumption of 40 kW. If, on an annual average, this installation is operated at the design point for 50% of the time and at half the rated air flow for 50% of the time, energy savings of 65 MWh per year can be obtained.

In an efficiency class of their own

Energy efficiency legislation is becoming ever more stringent. In Europe, the ecodesign regulation for motors (EU 640/2009) currently sets down IE2 as minimum efficiency class. With effect from 2015, the requirements of efficiency class IE3 have to be satisfied. Similar regulations apply in other countries – efficiency class IE3 is already mandatory in the USA, for example. The good news: GreenTech EC motors from ebm-papst already surpass the standards stipulated for efficiency class IE4, which means that you will be able to plan with more certainty well into the future.

And efficient does, of course, also mean economical. On top of that, demand-based speed adjustment ensures that energy consumption never exceeds what is actually required.
