Both come with a new compression element, an IE4-efficiency motor, oversized coolers, and a hybrid bearing that is claimed to extend the lifetime of the drivetrain by 33%. A 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 range of remote monitoring and system optimisation features.
According to Atlas Copco, the GA+ models deliver fixed-speed performance to provide more air, greater energy savings, and advanced connectivity - plus extra-long service intervals of 8,000 hours.
The GA+ 55-75 kW compressors come with a suite of features, including a smart temperature control system that calculates the oil-injection temperature based on operating conditions to help 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 leads to energy savings. Intelligent sensors will also monitor the pressure drop and any energy losses in the inlet filter, oil separator, and oil filter. Additionally, 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 compressors into their production network.
Ben John, business line manager, industrial air at Atlas Copco UK, said: “These new models set a new standard in energy efficiency, reliability and smart performance, giving our customers the peace of mind of having a best-in-class solution that significantly reduces their environmental impact and helps transition into smart, connected production processes.”
