VSDs ‘set a new standard’ in compressed air efficiency

Home Engineering HVAC VSDs ‘set a new standard’ in compressed air efficiency

ATLAS Copco’s new GA 22 – 37 VSDs (Variable Speed Drive) air compressor range deliver energy savings of up to 60% and an increase in Free Air Delivery (FAD) of up to 21%, compared to fixed-speed models.

That’s according to Atlas Copco Compressor Technique’s Business Line Manager for Industrial Air Division, Zandra van der Westhuizen, who said this puts the range in an efficiency class of its own.

“Considering that over 80% of a compressor’s lifecycle cost results from the energy it consumes, and that compressed air generation can account for over 40% of a plant’s total electricity, the unprecedented efficiency of our new GA 22 – 37 VSDs series is unarguably a game changer,” she said.

Additional benefits include “unsurpassed reliability” and smart connectivity features which bring Internet of Things (IoT) capability to the devices.

Van der Westhuizen said the GA VSD machines also perfectly align with Atlas Copco’s environmental standpoint.

“The 80% heat recovery capability and advanced connectivity features of these machines further boost efficiency levels, assisting customers and end-users in attaining their sustainability and productivity goals.”

Other innovations include the incorporation, for the first time ever in a compressor, of a Ferrite-Assisted Synchronous Reluctance motor. Unlike traditional Interior Permanent Magnet motors, the rotor uses ferrite materials to help preserve precious resources.

A significant reduction in the amount of energy needed is achieved thanks to Neos Next inverter technology, while the Boost Flow Mode allows users to safely boost their air compressor. This enables VSDs compressors to temporarily exceed their maximum capacity when stretched to the limits by production demand.
