VSD Air Compressor Atlas G26VSD+ FF 26kw Screw Oil Injected Built-in Dryer
GA37-110 VSD+.pdf
A new standard in compressor efficiency
Innovative
GA26VSD+ compressors are equipped with a leakage-free drivetrain designed by Atlas . It relies on a patented Vacuum Ejector System (VES), which avoids oil leakage in GA 30-75 VSD oil-injected compressors.
Smart and intelligent
• Unique inverter for air compressors.
• Integrated graphic controller, developed by Atlas , with control logic adapted to fit different operating conditions.
• Modular design with proven performance and efficient material usage.
Efficient
• On average 10% lower Specific Energy Requirement(SER) than fixed speed compressors. Energy consumption is typically reduced by at least 35% compared to an idling compressor.
• Minimized efficiency losses through a direct drive with an permanet magnet motor equalizing IE4.
• Optimized inlet flow at air-end through use of sentinel Valve to minimize pressure and air loss.
Built-in Dryer
• With dryer built-in, can help customer to save money, and more convience.
Reliable
• Low maintenance: Vacuum Ejector System (VES) creates a leakage-free system for GA 30 -75 VSD.
• Proven durability with modular design to ensure maximum use of parts.
• W-fin cooler for dependable performance in harsh environments.

VSD for more than 35% energy savings
Atlas ’s GA Variable Speed Drive technology closely matches the air demand by automatically
adjusting the motor speed. This results in energy savings of on average 35% compared to load/unload machines
Why choose Atlas Variable Speed Drive technology?
• On average, more than 35% energy savings with an extensive flow range (25-100% for GA 30-75 VSD)
• Integrated Elektronikon ® Touch controller controls the motor speed
• Unique NEOS inverter (for GA -75VSD)
• Oil cooled iPM motor means compressor can start/stop under full system pressure without the need to unload
• Eliminates peak current penalty during start-up
A step ahead in monitoring and controls
The next-generation Elektronikon ® operating system offers a wide variety of control and monitoring features that allow you to increase your compressor’s efficiency and reliability. To maximize energy efficiency, the Elektronikon ® controls the main drive motor and regulates system pressure within a predefined and narrow pressure band.
SMARTLINK*: Data Monitoring Program
• Remote monitoring system that helps you optimize your compressed air system and save energy and costs.
• Provides a complete insight in your compressed air network.
• Anticipates on potential problems by warning you up-front.
* Please contact your local sales representative for more information.
The after cooler
The compressed air is still very hot at this point, about 80 degrees Celsius. The compressed air is now cooled by the after cooler before it leaves the compressor. The air temperature after the cooler is around 25 – 40 degrees Celsius.
Because of the cooling down of the air, a lot of water vapor has condensed against the inside of the after cooler. This water is carried with the compressed air towards the air outlet of the compressor.
Of course we don't want all this water in our compressed air system.
Moisture trap
For this reason, a water trap (also called a moisture trap, moisture separator or condensate traps).
This can be a mechanical or an electrical version. The condensate trap basically separates the water from the compressed air. The water is drained through a small hose.
The compressed air now finally leaves the compressor.
Oil flow
But what about the oil? Remember the compressed air/oil mixture was separated by the separator?
The separated oil is hot. Is absorbed the heat of the compression and can be as hot as 120 degrees Celsius (anything more and the compressor will shut down).
The oil is cooled by the oil cooler. The amount of cooling is controlled by a thermostatic valve. If the oil is still cold, the oil cooler is completely by-passed. If the oil is very hot, all the oil is led through the oil cooler. The thermostatic valve regulates the oil temperature.
