EC medium pressure axial fans

GreenTech EC technology in a new dimension: EC medium pressure axial fans Thanks to the new axial fans, our highly efficient GreenTech EC technology is now available for the first time for the medium pressure range. Not only does this create new possibilities, it also makes things easier. With the EC medium pressure axial fans from ebm-papst, you get … … a complete system, consisting of a motor, impeller and integrated variable speed drive. All from one source and ready configured. That means no extra components and simple commissioning. In addition, you can be sure that all legal requirements have been fulfilled in line with the Ecodesign Directive for fans. Standardised measurements and clear documentation are available. … high adaptability. Because different operating points can be set by way of speed adjustment. The system can also be mounted in any desired orientation. … high efficiency. This is ensured thanks to the GreenTech EC motor in combination with the integrated variable speed drive. … an integrated derating function. The perfect protection against overheating and mechanical overload. Medium pressure axial fans with GreenTech EC motors are used wherever high volume flows need to be moved against elevated pressures. Examples of this include shock freezers or cold storage facilities, as well as process cooling applications.     EC medium pressure axial fans: Top of the class in efficiency   50 Hz; According to IEC 60034-30 The legal requirements for energy efficiency are becoming increasingly strict. According to the Ecodesign Directive for motors (EU 640/2009), the minimum efficiency class IE2 is valid in Europe. The efficiency class IE3 must be fulfilled as of 2015. Similar legislation applies in other countries. In the USA, for example, the IE3 efficiency class (premium efficiency) is already obligatory. The good news is that GreenTech EC motors from ebm-papst already exceed the IE4 efficiency class (super premium efficiency) today. This gives you perfect planning security for many years to come. Efficient also means cost-effective. In addition, the fan speed can be adjusted to requirements, meaning that you only use the energy that you really need.   EC medium pressure axial fans: Continuously cost-effective The adjustment of the air flow to the current requirements is a decisive factor for a system’s energy consumption. For AC fans, this is often achieved by switching individual fans on or off. In contrast, GreenTech EC fans have an integrated variable speed drive, which can be used to adjust the air mass to requirements. When the fan speed n is reduced, the input power P e decreases drastically (P~n³). A simple sample calculation makes the enormous potential for savings clear: A system with four fans arranged in parallel consumes 40 kW in rated operation. If this system is operated over one year, with an average of half the time in the design point and the other half of the time at half the rated air flow, this results in energy savings of 65 MWh per year.

Low-pressure centrifugal fans

Backward-curved fan blades with a rigid, hybrid design RadiCal centrifugal fans with backward-curved blades are the new standard in ventilation and air-conditioning. RadiCal features include both noise minimisation and a further decrease in energy consumption. The RadiCal impeller with backward-curved blades is made of fibreglass-reinforced plastic, enabling an aerodynamically optimised shape that cuts the noise level in half and reduces power requirements significantly. Optimised RadiCal impeller with backward-curved blades The designs for the impeller and the backward-curved blades were optimised with complex simulation models adjusted using measurements on prototypes. The result is an optimal, low-loss flow of air through the impeller without the drastic cross-sectional jumps that cause losses in the impeller. A uniform flow profile without laminar separation results in fewer noise sources and better acoustics. The plastic's good damping characteristics also help reduce noise emissions. The impellers are produced from a special composite material, in a single piece without joints. This makes a high circumferential speed possible, so the fan has a high power density. Even without special varnish, the impellers are highly corrosion-resistant, for example if exposed to salt water or salty air. Direct solar radiation has no damaging effects on the UV-resistant material.   Compact low-pressure series with miniaturised motor-electronics combinations GreenTech EC motors are used in the RadiCal low-pressure centrifugal fans. In terms of efficiency, they exceed legally mandated ErP limits. With these, up to 50% less energy consumption can be achieved in comparison with AC solutions. The motors in RadiCal low-pressure centrifugal fans have been miniaturised and are much more compact than their predecessors. With the current dimensions, easy and trouble-free replacement of existing AC solutions is possible at any time. The motor's heat management system also has an optimised design. The stator is completely encapsulated in high-performance plastic. Air inlets in the rotor guarantee perfect heat dissipation for the motor, resulting in a further considerable increase in efficiency. The high level of IP protection permits the use of these fans even in critical applications. The RadiCal with GreenTech EC motor features continuous control with a 0-10 V or PWM input signal. Versions with two fixed speed levels are available up to size 250 mm, with the higher speed providing a power reserve in comparison with the AC version. From size 250 mm, control via an RS-485 interface using the MODBUS RTU protocol is also possible.

Centrifugal fans with forward curved blades

Centrifugal fans with forward curved blades always require a spiral housing. Their characteristic features are a low noise level, relatively small air flow with a high increase in static pressure, and space-saving application. Energy savings, convenient control and low noise - Cylindrical rotor fans with GreenTech EC technology Saving energy is becoming an ever increasingly important topic these days. Especially when it comes to air-conditioning and ventilation technology, great potential savings can be achieved by using energy efficient fans. For this reason, motor and fan specialist ebm-papst has recognised the issue, and has developed a complete series of dual-inlet, direct-driven cylindrical rotor fans with efficient GreenTech EC technology. Without changing the design of the unit, this allows a conversion from a conventional fan with asynchronous motor to modern energy-saving technology. With integrated motor electronics, the EC fans can be easily speed controlled via a 0-10 V signal or by the use of a potentiometer. As an option up to three air flow values can be programmed in "Constant Flow" mode. This means that if the system resistance changes, for example due to polluted filters, the fan keeps the programmed air flow by changing the speed automatically. Depending on the motor type used, the double inlet fans with state-of-the-art EC technology cover almost every conceivable application area. You can choose between eleven sizes with drive outputs between 85 W and 3 kW. Thus a customised solution is available for virtually any application, including compact air handling units, air curtains, fan coil units, air heaters for factory buildings or as a cooling fan for forced cooling of power converters, generators or telecommunications systems.
