Fixed-speed smart industrial air compressors

As manufacturing makes the transition to smart factories, Atlas Copco launches its new generation of GA 55+-75+ which now bring intelligent performance to the mid-size, fixed-speed industrial compressor market. Atlas Copco is also introducing a new and improved GA 55-90.

The new GA+ and GA are both best-in-class mid-size industrial compressors that deliver more air at a lower energy cost than their previous generation. Both come with a new compression element, an IE4-efficiency motor, oversized coolers, and an innovative hybrid bearing that extends the lifetime of the drivetrain by 33%. A wide range of options allows customers to tailor their unit to their applications and requirements. 

Both models feature the advanced Elektronikon Nano Touch controller, which is SMARTLINK enabled as standard, meaning that customers benefit from a host of remote monitoring and system optimisation features.

The latest smart solutions offer a new and improved, quality-without-extras, GA 55-90 kW range while at the same time, the new GA+ models deliver premium, fixed-speed performance to provide more air, greater energy savings, and advanced connectivity – plus extra-long service intervals of 8,000 hours.

What really sets this new generation of GA+ 55-75 kW compressors apart is their new suite of innovative intelligent features, including a smart Temperature Control System that calculates the ideal oil-injection temperature, based on actual operating conditions, to maximise efficiency.

Also featured is a Smart Unload algorithm. Traditional fixed-speed compressors will run in unload for a long, pre-set time before switching off. In the GA+ models, the Elektronikon controller will track the pressure in real-time and calculate the ideal time to unload. Less time in unload means significant energy savings. Intelligent sensors will also constantly monitor the pressure drop and any energy losses in the inlet filter, oil separator, and oil filter. Finally, a smart no-loss water drain ensures automatic removal of condensate, auto-cleaning, and the detection of any potential disposal issues. 

By incorporating OPC UA – the machine-to-machine communication protocol – the new range allows customers to integrate their compressor seamlessly into their production network. 

Furthermore, these new features allow the GA 55+-75+ to improve its Free Air Delivery by 3.9% and its Specific Energy Requirement by 2.3%, outperforming its previous generation and its current competitors. Within its segment, the GA 55-90 records equally impressive numbers, with a Free Air Delivery and Specific Energy Requirement improvement of 4.0% and 2.5% respectively.
