The Largo 11-22E is an efficient fixed speed screw compressor that provides high performance to your production. The Largo E meets the compressed air demands in a wide range of industrial applications. This range ensures industry leading performances in air delivery and energy efficiency. We ensure our customers receive unrivalled energy savings for their operations.
The ALUP E Series
The Largo 11-22E fixed speed screw compressors are part of the ALUP E series. The ALUP E series incorporates the latest technological developments in compressed air. The ALUP E also ensures industry leading performances in Free Air Delivery and specific energy requirements. Lowering your energy consumption not only brings financial savings but is also is a sustainable solution for greenhouse gas emissions.
Top Performance
The Largo 11-22E provides top performance both in terms of Free Air Delivery (FAD) and Specific Energy Requirement (FER). This is thanks to the new and powerful Motor x element. With this element there is more air for the same kW installed and less energy consumption for the same air delivery.
Low Noise Levels
The Largo 11-22E has low noise levels ranging from 66 to 69dB(A). Equipment can be installed almost anywhere in the factory or workshop without any major disturbances to the working environment. The silent compressor can be installed close to the point of use to reduce installation costs and energy costs.
Powerful Cooling
With dedicated radial fans, the Largo 11-22E ensures low noise levels and low oil and motor temperatures. The design of this new Largo E series has an integrated turbine cooling fan for powerful cooling.
| The powerful radial fan guarantees: |
| Better air diffusion |
| Use of 100% cooling surface |
| Easy access to the cooler for blowing |
| Due to the unique design, the entire series can operate with open doors |
| Higher cooling flow compared to traditional axial fans |
| Lower energy consumption |
Gear Drive Power Train
Thanks to the combination of screw compressor technology and gear drive, there is no long-term losses. With a gear driven power train, these screw compressors provide up to 30% less thrust load on element bearings. Gear driven power trains are 3% more efficient than belt driven power trains.
Efficient Control
The Air Control 5.0 is an efficient control system and is standard with the Largo 11-22E fixed speed screw compressor. The Air Control 5.0 controller guarantees simple and intuitive day-to-day operation.
| Besides monitoring, controlling and protecting the compressor the controller also offers: |
| Intelligent unload cycle management |
| Icon based display |
| Remote start/stop |
| Compressor status |
| Automatic restart after power failure temperature readings |
| Pressure reading and setting |
| Running hours and loaded hours |
| Service maintenance warnings |
| Failure warnings |
| Online Visualisation (webpage) |
| Networking possibilities (slave controller) |
| Integrated dryer control |
Energy Efficient Options
Integrated energy efficient dryers use low Global Warming Potential (GWP) gases, the R404 A (11-15kW) and R410 A (18.5-22kW). To ensure maximum moisture removal, an oversized dryer is isolated from the hot area of the compressor. An internal water separator with an automatic drain removes up to 90% of the moisture. Two-line filters (optional G+C filters) can be integrated into the package to ensure clean air.
Easy Access
All consumables of the Largo 11-22E fixed speed screw compressor is located behind one panel for efficient serviceability. The front and rear panels are removable to allow any type of service. Very large service panels make access fast and easy. Servicing and cleaning are very simple and only requires one person.
Energy Recovery Option
The energy recovery option can recover up to 75% of the energy consumed. With this option, excess heat is captured and channeled into other applications to save energy and cut costs. The oil-circuit is pre-cooled with an oil/water heat exchanger in this option. The energy recovery option is a simple mechanical system that requires no maintenance or electricity consumption.
