Designed with sustainability in mind, ZenergiZe range from Atlas Copco, Stockholm, Sweden, helps operators dramatically reduce their fuel consumption and CO2 emissions, while delivering optimal performance with zero noise and virtually no maintenance. Leveraging the benefits of high-density lithium-ion batteries, the ZenergiZe units are compact and light compared to traditional alternatives, yet capable of providing over 12 hours of power with a single charge. They are ideally suited for noise sensitive environments, such as event or metropolitan construction sites, telecoms, or rental applications, or to resolve low load problems.
The firm’s new ZenergiZe storage system has a footprint of just 1.4 m2, and the two models in the launch range offer rated powers of 15kVA and 45kVA, as well as energy storage capacities of 45kWh.
The size reduction – the storage system is 70% smaller and lighter in weight than traditional standalone generators – is achieved by the use of high-density lithium-ion batteries.
“Advances in lithium battery technology mean that we are now able to deliver a product with the high reliability that our customers have come to expect from us,” said Bárbara Gregorio Bondía, product marketing manager.
In its hybrid mode, a ZenergiZe unit in combination with a QAS80 generator can reduce fuel consumption by up to 50% over 12 hours. A ZenergiZe unit only emits 50% of the emissions of a standard standalone generator, said the company.
When used in the island mode as the primary source of power, the emissions reductions can reach up to 100 percent if the unit is powered by renewable energy sources.
The system enables smart load management by helping the generator reach peaks of power. This optimises the generator’s performance and extends its lifespan, while also allowing its size to be reduced by 40%.
The company noted that in low load applications, a ZenergiZe unit can provide the required power for more than 12 hours without needing to be recharged, and that recharging takes only 1.5 hours.
