New Variable Speed Generator from Atlas Copco

Published: 17/6, 2019

Lack of fuel efficiency and managing variable loads are now a thing of the past with the introduction of Atlas Copco’s QAS 60/35 VSG Variable Speed Generator. The superior low-load performance of the QAS 60/35 VSG, which features automatic variable speed control from 950 to 2550 rpm and an integrated energy storage system, enables fuel consumption levels to be reduced by up to 40% against traditional fixed-speed generators. At the same time, it helps increase reliability in applications with an average load of less than 20%. The integrated energy storage system helps increase peak power capabilities by 70 per cent, matching the performance of a 60 kVA prime power generator. In addition, the QAS 60/35 VSG enables operators to reduce their carbon footprint, by offering CO2 emission reductions of up to 40%.

The plug-and-play, environmentally-friendly QAS 60/35 VSG is housed in a robust, sound-attenuated Zincor steel enclosure that is up to 55% smaller than comparable units. The QAS 60/35 contributes to operators’ uptime, productivity and revenues through service efficiency and extended engine lifetimes. A maintenance interval of 500 hours is made possible by the unit’s heavy-duty fuel filtration system and water separator. Similarly, engine lifetime is extended as a result of the dual stage air filter and safety cartridge features. Moreover, the new QAS 60/35 VSG allows customers to downsize and optimise their fleets, as one unit can replace up to six power nodes of a typical fixed speed generator from 9 kVA to 60 kVA. With a 1-to-1 ratio motor start capability, the QAS 60/35 VSG is the ideal source of high starting current for the electric motor drives of site equipment such as construction tools, cranes, pumps, or electric compressors. What’s more, the stable frequency and voltage makes it the solution of choice when coping with sensitive loads such as electronics equipment applications.
