The Allegro 11-22E is part of the ALUP E Series
The Allegro 11-22E variable speed screw compressor is a highly efficient machine suitable for a range of industrial applications. The high performing screw compressor meets the compressed air demands of industrial applications such as small industries and many more. As most industrial applications have a fluctuating air demand, the Allegro E series provides the ideal solution.
This is due to the very high Free Air Delivery and competitive turndown of up to 78%. The Allegro E series provides a wide product offer with 4 power sizes and two pressure variants. There are three configurations available; floor mounted, floor mounted plus dryer (plus) and tank mounted (500L) plus dryer (plus).
Variable speed technology can cut energy bills by up to 35% when used in the right application. The variable frequency drive compressor matches air supply with demand, therefore, reducing energy consumption when the demand is lower. Receive improved efficiency thanks to the new direct driven transmission.
The Allegro 11-22E can be installed inside the factory or workshop without major disturbances to the working environment. This is thanks to the low noise levels ranging from 66 to 69dB(A). The almost silent machine can be installed close to the point of use. This will minimize installation and energy costs spent on covering pressure drops.
The gear drive is 3% more efficient than belt drive and there is no need for constant belt tensioning. There will be no long-term losses thanks to the combination of screw compressor technology and gear drive. With up to 30% less thrust load on element bearings, you can expect a longer element lifetime.
A new and powerful motor and air end combination provides top performance FAD and Specific Energy Consumption. This results in more air per kW and less energy per m³/h. The IE3 TEFC – IP55 Class F Siemens Motors are from a reputed supplier with worldwide support.
This new Allegro 11-22E variable speed screw compressor series has an integrated turbine cooling fan.
|The powerful radial fan guarantees:|
|Higher cooling air flow compared to traditional axial fans|
|Lower energy consumption|
|Better air diffusion|
|Use of 100% cooling surface|
|Easy access to the cooler for blowing|
|Due to its unique design, the entire series can operate with open doors|
The Air Control 5.1 controller comes standard on the Allegro 11-22E to provide extended control, monitoring and operation possibilities.
|In addition to all the features of the standard controller, the graphic controller offers:|
|Highly visual graphic interface|
|32 different languages|
|Central control possibilities (Master controller)|
|Up to 6 compressors|
|Start/stop timers2 progammable pressure bands|
|Graphic service plan management|
The energy recovery option can recover up to 75% of the energy consumed. This option captures excess heat and channels it to other applications allowing you to save energy and cut costs. The energy recovery option integrates a heat exchanger on the oil circuit, which heats up the continuous pressurised water flow. The energy recovery option offers significant reductions in energy costs.
An internal cyclonic water separator with automatic drain removes up to 90% of the moisture. Integrated dryers use low GWP (Global Warming Potential) gases, they are R404 A (11-15kW) and R410 A (18.5-22kW). An oversized dryer is isolated from the hot area of the compressor ensures maximum moisture removal. There is the option of two-line filters (G+C) filter to be integrated in the package.
Consumables are located behind one panel for efficient service. To facilitate any type of service, the front and rear panels are removable. Very large service panels make access fast and easy. These features make service and cleaning a simple, one-person job.
With the Allegro 11-22E variable speed screw compressors you will receive energy savings in a very short time. These energy savings will pay back the investment made in our Premium Inverter Driven Compressor and decrease function costs. We are your partners in compressed air and will support you from the very beginning. We offer quality products and exceptional service.
