The Efficient Largo E Fixed Speed Screw Compressor Series

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.

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.
