Ebmpapst wons “the product innovation award” in shanghai CRH 2017 for its radical centrifugal fan in scroll housing
As technological leader for ventilation and drive engineering, ebm-papst is in demand as an engineering partner in many industries. With over 15,000 different products, we provide the right solution for just about any challenge.
Their fans and drives are reliable, quiet and energy-efficient.
Designed for the future: RadiCal with scroll housing.
The ecological demands placed on residential ventilation equipment have become much more stringent. It needs documented improvements in energy efficiency and has to be automatically adjustable. And, of particular importance for residential use, it has to be especially quiet. The backward-curved centrifugal fan with scroll housing from ebm-papst is considerably more efficient than forward-curved fans and allows ex-act balancing of the intake and outflow rates. A crucial benefit: On backward-curved fans, air flow sensors previously had to be retrofitted in a costly and time-consuming process. With the new plug & play solution from ebm-papst, this and other features are already integrated. Typ-ical applications for RadiCal include central ventilation systems for single- and multi-family houses as well as industrial applications.
The RadiCal series of backward-curved GreenTech EC fans now comes installed in a special housing. This all-in-one single-source solution consists of an impeller, a GreenTech EC motor with integrated control electronics, and a scroll housing, all of which are perfectly matched for ideal efficiency and acoustics.
There are three high-efficiency GreenTech EC motors to choose from, with 85, 115 and 170 watts. They shine with an efficiency over 30 % higher than that of comparable EC centrifugal blowers. Special features include air flow measurement with a vane anemometer (patent pending), a MODBUS-RTU interface, and connections for additional sensors for optional temperature and humidity monitoring.
An extra benefit, especially for residential applications, is the significantly reduced noise level. In comparison with EC centrifugal blowers of the same size, the RadiCal is 3.5 dB(A) quieter. And it also has an ace up its sleeve for installation: no preparation required thanks to plug & play. Incidentally, the RadiCal with scroll housing is also available with a 2-pole, single-phase asynchronous motor.
