New standard for compressor efficiency
Atlas Copco's GA45-75VSD permanent magnet inverter compressor's ingenious drive and intelligent control give it unprecedented reliability and efficiency. The series is a variable speed drive compressor with built-in permanent magnet motor (iPM) and a unique compressor-specific frequency converter. The GA45-75VSD can reduce energy consumption by at least 35% on average, setting a new benchmark for cost savings and stability in the air compressor industry.
Innovation
The GA 45-75 VSD compressor is equipped with a leak-free drive system designed by Atlas Copco. It features a patented Vacuum Return System (VES) that eliminates leakage from the shaft seal of the oil-injected screw compressor.
Sophisticated, intelligent
• Special frequency converter for air compressors
• Atlas Copco color screen controller with variable speed control logic for different operating conditions.
• Adopt market proven and efficient design and parts
Efficient
• Compared to the fixed speed, the series is 10% lower than the power consumption (SER) at the maximum air volume. When the demand for gas is drastically changed, the average energy saving of the compressor driven by the variable speed is at least 35%.
• Minimize efficiency losses with IE4 efficiency grade motors and direct drive.
• The unique intake valve optimizes air flow into the screw rotor, reducing pressure drop and air loss.
reliable
• Low maintenance: a leak-free drive system with a vacuum return system.
• Modular design to maximize the use of proven designs and parts for proven models.
• W fin cooler ensures stable performance in harsh environments.
Permanent magnet drive VSD series saves more than 35%
Atlas Copco's GAVSD is perfectly adapted to the customer's air demand changes by the variable speed of the motor. It can save energy consumption by more than 35% on average.
Why choose Atlas Copco's variable speed technology?
• The average energy savings exceeds 35% when the demand for gas consumption changes drastically (25-100%).
• Elektronikon controller controls motor speed
• Unique NEOS inverter
• Oil-cooled iPM motors can be started/stopped at full system pressure without unloading
• No start peak current
