Lack of fuel efficiency and managing variable loads are now a thing of the past with the addition of the QAS 60/35 VSG Variable Speed Generator to Atlas Copco’s QAS mobile generator range. The QAS 60/35 VSG Variable Speed Generator, is a game changer in terms of operational savings, performance and reliability.
According to Richard Crowe, Executive General Manager of Atlas CEA the proprietary Variable Speed Generator (VSG) technology embodied in the QAS 60/35 completely eliminates the inherent risks associated with low-load generator operations such as cylinder glazing, bore polishing, heavy carbon build-up, high oil consumption, low combustion temperatures and fuel waste.”
QAS 60/35 VSG, the game changer
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 per cent against traditional fixed speed generators.
At the same time, it helps increase reliability in applications with an average load of less than 20 per cent, such as construction projects, outdoor events or telecommunication service duties. 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 per cent.
“The QAS 60/35 contributes to operators’ uptime, productivity and revenues through service efficiency and an extended engine lifetime. A maintenance interval of 500 hours is made possible by the unit’s heavy-duty fuel filtration system and water separator,” says Richard. 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 it produces makes it the solution of choice when coping with sensitive loads such as electronic equipment applications,” adds Richard.
“The features that really set the QAS 60/35 apart are the VSG technology for low load operation and its power of connectivity. This latest addition is unrivalled when it comes to flexibility, thanks to modular design and paralleling capability that enables it to connect multiple generators in the simplest way for optimum efficiency,” says Richard.
