New IP66-rated oil-injected screw compressor

Jon Lawson

Atlas Copco has launched its new GA 90+-160 VSD+ oil-injected screw compressor range. It features compression elements with Smart Injection technology coupled with highly efficient oil-cooled IE4 and IE5 motors that require no service interventions. The new Elektronikon Touch controller with integrated smart algorithms further reduces energy consumption. It is available in water- and air-cooled versions, with fixed or variable speed drive and with an optional integrated dryer.

“The latest generation of GA compressors are particularly well suited to metal processing and power plants, where the IP66 drivetrain offers complete protection from environmental dust and moisture to ensure reliable operation in ambient temperatures up ​to 55°C,” said Stef Lievens from Atlas Copco Compressors.  

Optimum efficiency is ensured through an efficient drive train, ​low internal pressure drops and precise control from the Elektronikon Touch. ​All components are designed for ease of service, with the most commonly serviceable parts grouped together for ease of access. Meanwhile, the patented portal design enables full access to all components when more extensive maintenance is required. This results in a service time that is half that of some other designs.

The GA 90-160 VSD+ range features the new Optimizer 4.0 central controller, which replaces the company’s ES16 central controller. It enables a compressed air system to be optimised through selection of the most efficient combination of machines, such as compressors, dryers, filters, controllers, energy recovery systems, generators, air receivers, coolers and boosters. Through a user interface the end-user can view the performance and energy consumption of each machine as well as of the whole system.

Optimizer 4.0 can also be monitored through a customer’s PC via LAN, a SCADA system or Atlas Copco’s Smartlink remote data monitoring system. It is fully Industry 4.0 compatible, enabling the digital integration of the air compressed system with other intelligent networked devices to improve equipment performance, enhance predictive maintenance and further increase energy efficiency.
It’s offered with a 5-year warranty.
