Allegro 31-110 Screw Air Compressors

The Allegro 31-110 screw type air compressor range provides high-quality compressed air for a wide range of industrial applications. The Allegro 31-110 screw compressors stand out as they have been built around innovative features. This screw compressor range is the result of continuous investment in product development.

Better Energy Efficiency

You can expect a lower pressure drop in the Allegro 31-110 thanks to the removal of valves downstream air end. This will result in better energy efficiency to your compressed air system. A repositioned outlet grating also results in less pressure drop, lower power consumption of the cooling fan and better energy efficiency.

Radial (or Turbine) Fan

Instead of an axial fan, the Allegro 31-110 screw air compressors use a radial fan (or turbine). The radial fan is located above the main motor and distanced from the cooler. 

The benefits of using a radial fan are:
Superior energy efficiency
Better cooling
Low rotation speed
Uniform diffusion of the air
Better efficiency
100% use of the cooler
Lower operation temperature
Lower energy consumption
Expand lifetime of the machine
Reduced noise levels

High-Quality Cooling

There is a separate oil and air cooler in the Allegro 31-110 screw air compressor range. This ensures high quality cooling and a long lifetime of the coolers. Gliding rails on the coolers are included for easy and safe removal. There is also improved motor cooling in these screw compressors thanks to a separate cooling flow.

High Inlet Filtration Quality

The Allegro 31-110 screw air compressor range provides high inlet filtration quality. An encapsulated air filter preserves the machine against dust. A pleated 2-micron media allows for a larger filtration surface area. 

The benefits of high filtration include:
Expanded oil lifetime
Expanded filters' lifetime
Rapid access for maintenance
No tooling required
Maintenance cost reduction

Small Installation Footprint

One frequency driven machine for one load unload machine allows perfect fit of the installation. The frequency driven machine can be one size bigger than the load unload machine in all the installations. With a small installation footprint, the Allegro 31-110 screw air compressor can be placed against a wall. Insulation foam reduces the noise of the screw compressor.

Multiple Compressor Controller

Compressed air installations with multiple compressors can now be controlled with the EC0ntrol 6. This is a simple and central controller which reduces energy consumption in installations of up to 4 or 6 compressors. 

Control features include:
Single pressure measurement point
Minimised pressure band
Stable system pressure
Equalisation of running hours
Multiple IVR speed control
Clear and visual graphical display
Online monitoring and controlling possible

Intelligent Monitoring

With the Airlogic, you get intelligent control of the Allegro 31-110 screw air compressor range. The Airlogic is a full colour 4.3” HD touch display control system. 

The features of the Airlogic include:
Intelligent unload cycle control
Warning indicators
Graphical indication service plan
Built-in online monitoring

Intelligent Connectivity System (ICONS)

The Intelligent Connectivity System is ready to go and allows you to benefit from all the advantages of ICONS:
Remote monitoring that helps you optimise costs and ensures a longer machine life
On-time maintenance which optimises costs and ensures a longer machine life
Potential problems are recognised before they can pose a threat to the stability of your production

Eliminate Risk of Leakages

 An in-house designed oil separator vessel integrates minimum pressure valve (MPV) to eliminate risk of leakages. Cast iron parts allow for a long lifetime of the part. The oil separator vessel has been designed for optimal oil separation. An integrated imperium inverter is installed in a separate cubicle to ensure optimal cooling and an easy maintenance.

Variable Speed Technology

A major focus of your compressed air installation should be the energy consumption. Energy costs represent 70% of the total operating cost of your air compressor over five years. Variable speed technology, like the Allegro 31-110 screw air compressor, can cut energy bills by 35% in the right application. The variable frequency screw compressor matches air supply with demand therefore reducing energy consumption when the demand is lower.

Energy Recovery Option

Another way to control energy consumption is with the energy recovery option. The energy recovery option captures excess heat and channels it to other applications. This will allow you to save energy and cut costs. The energy recovery option integrates a heat exchanger on the oil circuit, which heats up the continuously pressurised water flow.

Integrated Dryer Option

The Allegro 31-75 screw air compressors are available with an integrated air dryer option. This option offers significant advantages compared to a stand-alone dryer.

These advantages include:
Condensation removal at source minimising pipework corrosion
Reduced footprint, up to 1/3rd of a stand-alone dryer
Intelligent dryer control
Higher operating temperatures compared to stand-alone
Single service visit which reduces maintenance costs
No installation cost

Wide Range of Options

Our industrial screw compressor options include quality components. An internal water separator is optional in the Allegro. This can be combined with an automatic drain to ensure there is no air loss during condensate removal.
