Energy saving inlet guide vanes

Inlet guide vanes save up to 9% in energy at reduced air demand.

They increase the turndown capacity of the compressor due to

accurate regulation of pressure and flow close to surge.

Optimize your installation

Tailored to the application, Atlas Copco has

developed complementary equipment for the optimal

quality air solution and the lowest cost compressed air.

Energy-free XD adsorption dryers

If your process needs dry air, add the unique and environment

friendly XD adsorption dryer, combining the best technologies –

heat of compression regeneration and twin tower design.

ES – Energy Saving control and monitoring systems

The Energy Saver compressor room controller communicates

with the individual Elektronikon®

controllers and optimizes the

energy efficiency of the complete system, reducing the overall

pressure band. Each compressor operates in its optimum

working zone and the net pressure is kept within tight

boundaries. The benefits are multiple: substantial energy

savings, improved reliability and increased lifetime of the

machines.

For each ZH hot air variant, there is a matching XD to

obtain the most stable dewpoint.

General range: 1400 - 7000 l/s (2900 - 14800 cfm).

The XD-S model uses the heat of compression for regeneration,

resulting in a negligible energy consumption; the dewpoint

is -10 to -20 °C, depending on the ambient conditions.

The XD-G model combines heat of compression and internal

heaters to offer a constant dewpoint of -40 °C, regardless of

the ambient conditions.

The ES allows for remote monitoring and condition based

maintenance: Atlas Copco’s AIRConnect TMand AIROptimizer TM

contracts provide for the ultimate peace-of-mind and the

lowest energy cost throughout the life cycle of your compressed

air system.

can do for you!

True performance

When specifying the true performance of an air

compressor, at least three parameters must be considered:

Capacity

The standard to which the capacity is measured

Working pressure

The point where the delivery pressure is measured

Power consumption

The compressor package power required at an effective

working pressure (including all internal losses from inlet

to outlet).

The main drive motor efficiency.

Atlas Copco ZH compressors are measured according to

ASME PTC 10, stipulating the FAD measurement at the

outlet of the package, net of all losses.

Atlas Copco specifications correspond to the capacity and

pressure which the customer receives, not to what the

compressor sucks in. Differences are substantial.

Intake volume

Inlet flow referred tocompressor element inlet

conditions. Seal leakages andinlet losses should not deprive

you the air you paid for.

Delivered volume
