The new generators, ranging from 875 to 1420 kVA, build upon the success of the original QIS range and offers low-noise levels and modular capabilities: with 30 per cent more interior space available to allow for expansions or the inclusion of extra communications modules.
“The latest additions to the QIS range offer a no compromise solution to noise. We have tested and certified a 1 MW generator at a noise level of 70 dB(A) at 15 metres distance, which means they are suitable even for use in residential areas,” said Julio Tome, Product Marketing Manager – Large Generators, for Atlas Copco’s Portable Energy division.
QIS models are intended for outdoor installation and undergo the most rigorous testing procedure on the market, including a transient behaviour test, ambient temperature performance test, water ingress test and certification, along with extensive noise testing. These features not only minimise environmental impact but also guarantee performance under any conditions.
They deliver fuel consumption savings of 5 per on average, are up to four times quieter; and have a 25 per cent smaller footprint than comparable models on the market. All of the generators feature premium engines with high load acceptance, in addition to an IP23 alternator with auxiliary winding that withstands 300 per cent overcurrent during the first 20 seconds. “This ensures an instant start, guaranteeing power and performance at exactly the moment it's needed”, explains Tome.
The compact design of the generators makes them ideal for overseas transportation, with integrated lifting slots to support the process. Moreover, the plug-and-play design enables simple and fast installation. All units also come with a spillage free-frame, made to contain all fluids inside the machine.
The new models are the QIS 875, QIS 1015, QIS 1115, QIS 1250 and QIS 1420. All offer 500-hour service intervals and are designed to perform reliably and efficiently in both standby and stationary prime power applications: across market sectors including data centres, healthcare, manufacturing, utilities and retail.
Service downtime is reduced further if end users choose to integrate optional features such as a heavy duty fuel filtration system with water separator, dual stage air filtration and oil drain pump. Additionally, all the latest models provide easy access to key internal components, for instance the engine, alternator (AVR and diode bridge) and radiator, via large service doors and panels.
