Atlas Copco has announced the launch of a new generation of its VSD compressors — the GA VSDS — which the company says “is the most energy-efficient, sustainable compressor on the market today”.

This 22-37kW GA oil-injected screw compressor range is the third generation of Atlas Copco’s variable speed drive (VSD) compressors, which significantly reduce energy consumption by adjusting their motor speed to the fluctuations in compressed air demand.

When Atlas Copco introduced the technology, a first-generation VSD compressor achieved energy savings of up to 35% compared to a fixed-speed compressor. That number increased to 50% with the company’s VSD+ range. Now, the new GA VSDS offers energy savings of 60% — and a high level of sustainability. The manufacturer says the new unit not only comprises a minimum number of components but also features an IE5 ferrite-assisted synchronous reluctance motor that does not rely on rare earth materials in its operation.

“With a free air delivery that is 21% greater than its fixed-speed counterparts, the VSDS introduces a host of smart features that allow it to adapt and optimise performance to user’s applications, requirements and conditions. For example, the smart temperature control (STC) system ensures that the compressor operates with an optimal oil temperature at all times, eliminating the risk of condensation while ensuring maximum compression efficiency.

“The GA VSDS also comes with the all-new boost flow mode, which gives customers the freedom to exceed their compressor’s maximum capacity temporarily and safely; and with sound levels as low as 63dB, the GA 22-37 VSDS can be installed on the production floor, where it occupies a minimum footprint, thanks to its compact vertical design.

“The units also offer connectivity features, such as the Elektronikon Touch controller, the EQ2i multiple compressor control (integrated as standard), Smartlink remote monitoring and analysis, and OPC UA integration for connected production environments.”
