TRUSTED POWER SUPPLY FOR CONSTRUCTION SITES Construction sites, whether they are in urban or rural areas, are heavily dependent on a dependable source of power. In South Africa, with its often erratic national power grid, it is vital that sites that use the grid as prime source of energy, can seamlessly switch to power generated on-site, while construction sites in rural areas need a power generator that is dependable and fuel efficient. The majority of construction sites are off the grid and requires gensets as the primary source of power. based on this modular concept – for example, one cylinder head can be fitted to the 9, 13 and 16 litre engine. There are various advantages: it makes maintenance and repairs more straight- forward, less spare parts have to be kept in stock,” explains Walter.

The modular nature of the engines make them interchangeable too. “In terms of capacity, we have anything from 250 kVA up to 700 kVA Prime Power. Some customers need say 700 kVA during the day and only 200 kVA during the night – thenwe can install twomachines that will take care of that need – when less power is needed, one will automatically shut down and “Everything starts with a very old saying: no machine is better than its own service. Here Scania prides itself in the fact that with every genset sold, we offer customised repair and maintenance contracts. This allows us to ensure that our customers’ uptime remains as high as possible,” says Walter. “Our Scania gensets are built with a clear focus on low fuel consumption, dependability and maximum uptime. We develop them further to satisfy the power load that is needed by the client in power generation,” concludes Walter. vice versa,” says Walter. Ensuring uptime

national grid, a changeover switch is installed,” explains Walter. Walter says that a robust open and more soundproof canopy version of gensets are avail- able in South Africa. “The canopy version is popular as it has a hook on top of the canopy – it is easy for a truck-based crane to pick it up and transfer it to the next construction site. It is a concept that is used widely elsewhere in the world. The robust open version can also be fitted into purposely built containers. Modular engines – perfect for gensets All Scania engines are modularised and based on a unique cylinder design that produces excellent performance and fuel economy. The fact that all the engine designs have the same chamber design, makes it easier to strike the right balance between performance, emis- sion and fuel economy. Scania engines develop high torque within a broad rev band – perfect for construction sites. “Scania’s 9, 13 and 16-litre engines are all

trial, marine and power generation, offers the construction industry a range of engines for power generation on site – that will suit the specific need of the customer. Scania gensets Rune Walter, export sales manager – engines for Scania South Africa, says Scania’s well- known modular design has redefined reli- ability, safety and efficiency. “Scania gensets are true Scania from inside out – our construc- tion customers are getting industry-leading quality in every detail and user-friendly inter- faces for maximum convenience and safety. Our gensets are easy to install, ready to run and deliver electrical power whenever and wherever it is needed.” The complexity of the genset installation is dependent on the construction site. “If the site requires the power generated by the genset to be distributed to their distribution board, is it a matter of installing four cables from the genset; while at a construction site that will also use the

Warranty • The standard warranty is 12 months – based on prime power operation and unlimited hours. If it is stand- by power, the warranty is for 24 months – a maximum of 200 hours power generation per year. • The gensets can also be sold with a 36 month warranty – on condition that the customer has a maintenance contract with Scania. It will then be on those main components on the genset that Scania looks after: radiator, intercooler, complete engine and alternator.
