Rotary Screw Variable frequency Compressor Atlas GA37VSD+ FF 37kw
A new standard in compressor efficiency
Innovative
GA37VSD+ 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.
Atlas ’s GA37VSD compressors feature smart drive and intelligent
control for unprecedented reliability and efficiency. Variable
Speed Drive is integrated as standard, along with an Integrated
Permanent Magnet motor and a unique air compressor inverter. As a
result, the GA 7-75 VSD
reduces energy consumption by an average of at least 35%, setting a
new benchmark for cost savings and sustainable performance in the
compressor industry.
SIL Smart inlet lock system for GA VSD compressors
• Superior designed vacuum and air pressure controlled valve with
minimal pressure drop and no springs.
• Smart stop/start which eliminates back-pressure oil vapor.
Separate oversized oil cooler and aftercooler
• Low element outlet temperatures, ensuring long oil lifetime.
• Removal of nearly 100% condensate by integrated mechanical
separator.
• No consumables.
• Eliminates possibility of thermal shocks in coolers.

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.
Optional multiple compressor controller
The optional multiple compressor controller gives you easy,
centralized control to reduce system pressure and energy
consumption. Only one license is required for installations of up
to 2 (EQ2i), 4 (EQ4i) or 6 (EQ6i) compressors.
