Atlas Copco Stationary Air CompressorsGA30-90C WorkPlace Air SystemTM

30-90kW/40-125HP oil-injected rotary screw compressors

Introducing the WorkPlace Air System ™

The corner stones of the WorkPlace concept

Low noise

The noise level of the WorkPlace Air SystemTM is little more than that of a sewing machine

thanks to advanced design techniques and modern materials and components.

Outstanding performance

The WorkPlace Air SystemTM combines the most coveted screw element design with the most

advanced control system, resulting in more air for less power.

Complete integration

Both air treatment and condensate management equipment can be fully integrated into the

compressor canopy, reducing space and simplifying installation work.

Best customer choice

The WorkPlace Air SystemTM is available from 7.5-125hp, as either air or water cooled with a

wide range of operating pressure between 60-188 psig to meet any customer requirement.

Atlas Copco's unique WorkPlace Air SystemTM

delivers unrivalled user value. The WorkPlace Air

SystemTM allows the compressor to be moved out of

the compressor room and installed directly at the point

of use.

The dramatically low noise level eliminates the need

for a separate compressor room, while the integration of

all necessary air treatment and condensate management

equipment significantly reduces the required

installation area.

The only compressed air system that can be placed anywhere

Total system control and monitoring

The unique Atlas Copco Elektronikon® control system not only optimizes the running of the

compressor, the air treatment and the condensate management equipment, but it also allows

total remote monitoring, control and protection.

Faster, less expensive and easier installation

The cost and complexity of the installation is minimized by integrating all necessary air and

condensate treatment equipment. This integration also eliminates the interconnecting piping

and dramatically reduces the footprint of the whole installation.

Reduced running costs

Atlas Copco GA VSD compressors offer even further opportunities to reduce the energy cost of

operating an air compressor. Most production facilities show an air demand profile with wide

fluctuations that traditional compressor regulation systems can not follow in an energy efficient

manner. A GA VSD compressor is able to follow fluctuations in demand efficiently by varying

the speed of the drive motor to perfectly match the compressor's output to the varying plant

demand. Energy savings with GA VSD compressors of up to 35% are not uncommon over

traditionally regulated compressors. In addition, the integration of air treatment equipment

reduces costly pressure drops and risks of leaks which often account for 10% of the total

compressed air consumption.

Outstanding reliability

The complete WorkPlace Air SystemTM range is designed, manufactured and tested in

accordance with ISO 9001, ISO 14001 and ISO 1217 ed. 3 annex C respectively. Each and every

unit is tested before leaving the factory, ensuring that the high expectations of today's industry

are not just met, but exceeded.

Reduced maintenance costs

The WorkPlace Air System is designed with maintenance costs in mind. Long service intervals

combined with a mechanical friendly layout, ensure low costs and minimal down time.

Total Air System ControlElektronikon® - The superior choice

Atlas Copco’s patented Elektronikon® is an advanced

microprocessor based, real time operating system, which

allows comprehensive control and monitoring, through a

clear and simple user interface.

Total air system control

Elektronikon® goes beyond the traditional boundaries of

a compressor controller. Signals from related equipment, such as

coolers, filters or dryers can be sent back to the Elektronikon®,

which can then be configured to display readings or even take

certain actions based on the incoming signal.

A full complement of digital input and output signals facilitates

simple remote control.

Built in multi-compressor sequencer

Each Elektronikon® has the unique MCC, Multiple Compressor

Control, built in. MCC efficiently coordinates individual regulators in

a multiple compressor installation.

The MCC reduces the system operating pressure, increases the

pressure stability and optimises the maintenance schedule.

All this results in considerable savings on the operation of your

compressed air plant.

Complete remote monitoring and interface

If remote monitoring is required, there is no better alternative.

With the addition of one ComBox, an Elektronikon® installation

can be accessed directly from a PC or via an existing building

management system, using a choice of protocols.

Through participation in our various AirMonitor services,

an Atlas Copco compressed air system can be monitored

over the Internet.

Integrated service scheduler

Elektronikon® closely monitors the compressors, taking notice of

the run hours, both loaded and unloaded, as well as the status and

performance of certain crucial parts. Based on this information,

the optimum time for preventative maintenance is calculated and

displayed on the screen, ensuring continuous, smooth and trouble-

free operation of the unit.

Full equipment management and protection

Elektronikon® provides total control and complete protection of the

machine. Continuous and extensive monitoring ensures that the

operating efficiency is maximized at all times.

A complete compressed air solution contained in a single package

The high cost of low quality air

When the air that surrounds us is

compressed, its vapor and particle

concentration increases dramatically.

The compression process causes the oil and water vapors

to condense into droplets, and then mix with the high

concentration of particles. The resulting mixture is an

abrasive, oily sludge that in many cases is also acidic.

Without air treatment equipment, much of this corrosive

sludge will enter the air net, corroding the pipe work,

damaging pneumatic tools and potentially compromising

final product quality.

The quality air solution

The WorkPlace Full FeatureTM machine offers a unique air

treatment solution. In addition to the compressor, all air

treatment and condensate management equipment can be

integrated into the compressor canopy, ensuring that your

compressed air supply is both clean and dry. Aside from

providing clean, dry, compressed air, the Full Feature

machine offers a more optimized, quiet and space saving

package, which is fast, easy and less expensive to install.

When quality air is required, there is no better choice

than a WorkPlace Full FeatureTM machine.

Individual applications require individual solutions

An integrated heatless desiccant dryer, complete with

filtration, provides process quality air for the most

demanding applications. Complete with dewpoint

dependant switching control as standard, the units are

extremely energy efficient, ensuring maximum air for

minimum power.

Condensate quality must meet legal measurements.

The optional OSD oil-water separator raises the

condensate quality to surpass legal requirements, so

there is no need to worry about discharging oil

contaminated condensate.

Integrated filtration removes both particles and oil from

the air, eliminating the risk of damage to equipment and

contamination of the final product.

The integration of a refrigerant dryer eliminates virtually

all water from the system and prevents corrosion in pipes,

tools and instruments.
