CUMMINS TO POWER UP MEE 2018 WITH LATEST PRODUCTS

Lithium-ion (Li-ion) energy storage integration for high reliability.” The newest member of the Galaxy V family of power protection solutions, Galaxy VX, seamlessly integrates into the electrical, physical and monitoring environments of customers’ operating data centres, industrial or facilities applications. Built with growth in mind, the robust solutions feature a modular, distributed- component design that scales power system redundancy and capacity through incremental 250 kW-per unit power cabinets. In addition, by featuring two I/O cabinets, Galaxy VX eliminates the need to change the I/O cabinet when upscaling the power rating, enabling power cabinet internal redundancy. This architecture enhances overall system reliability, reduces mean time to repair (MTTR) Pacific. One project is the development of solar agro-mills for the country’s main crops, which cannot be eaten without processing. Agro-milling enables women in the area to reduce manual labour through cleaner, simpler, safer and quieter solar-powered micro-milling technology. The mills are leased to local female entrepreneurs using pay-as-you-go financial technology to create an affordable finance package. A mill therefore serves the needs of the wider community, and becomes the entrepreneur’s livelihood. To deliver what the entrepreneur needs to run her business, it is essential that the system includes technology, which effectively measures the dc energy being consumed. The system therefore needs connectivity – which is where the power of the Internet of Things (IoT) becomes imperative. Using a SIM card, the data can automatically be collected and sent directly to VIA. Vanuatu has several mobile network operators. The problem, however, is that no one operator covers the whole area. This means entrepreneurs leasing mills cannot be assured of their connectivity. With Eseye’s help, VIA has used AnyNet technology to supply pay-as-you-go solar technology. The SIM’s enhanced features also enable IoT devices to remotely and securely activate, provision, authenticate and certify devices or ‘things’, in field, over-the-air. Integration with AWS Cloud Services simplifies project set up and deployment by reducing the need for investment in specialist in-house infrastructure and development resources. By adding AWS’ software tools and cloud the business establishes the means to simply and quickly analyse data and to scale instantly, and securely, on demand. unit where the heat pump is mounted on top of the water tank. Heat pumps are proven to use roughly a third of the electricity required to heat the same amount of water in a conventional geyser element. The range includes two 60 °C integrated heat pumps for residential use, 55 °C and 60 °C split hot water heat pumps for residential, hotel and commercial use, 70 °C split hot water heat pumps for hotel and commercial use and 80 °C split hot water heat pumps for laundry, diary and medical use. The heat pumps are manufactured using the latest technology and best possible materials. All parts and components are carefully selected and tested to ensure ultimate efficiency, reliability and durability. EVI technology combined with highly Enquiries: www.eseye.com

SCHNEIDER ELECTRIC has expanded its Galaxy V-Series uninterruptible power supply (UPS) solutions for data centre and industrial applications. Galaxy VX’s extended power ranges, available from 500 kW to 1500 kW, answer the need for high availability by providing complete, versatile, power support for a diverse data centre market, including mid-to-large and hyperscale data centres that require an increasing amount of power for continuity and reliability of service. “As cloud computing and co-located IT models continue to expand in the enterprise, there is a growing focus on energy efficiency to support the move to hyperscale data centres globally,” says Riaan de Leeuw, VP for IT Division - Anglophone Africa Schneider Electric. “The Galaxy V-Series global platform offers high-efficiency modes, scalability, modularity and V illage Infrastructure Angels (VIA) exists to provide rural villages in developing countries with the infra- structure they need to reduce poverty and improve living standards. This includes help- ing people to access electricity for the first time. Eseye, IoT M2M connectivity specialist, has helped VIA to set up pay-as-you-go so- lar technology in rural villages. VIA turned to Eseye to deliver highly secure and reliable global cellular network data through its AnyNet Secure™ SIM. The AnyNet technology provides automatic routing onto up to 440 cellular operators in 190 countries and links seamlessly to the AWS Cloud. Smartly designed technology, finance and IoT also has the capacity to supply power to an entire micro-energy infrastructure. Jeremy Potgieter, Eseye, Regional Head, SADC, says the VIA project is an excellent example of what can be achieved in Africa, using the same approach: “Pay-as-you-go solar technology can be applied in several instances across Africa.” These kinds of labour saving assets have the potential to free 300 million women worldwide from one hour each day. Those collective 100 billion hours every year could be used to generate additional income or to give more attention to other activities. “We are able to measure the daily power generation from solar panels and the daily power consumption via customers. This gives us an understanding of whether the service is being over or under-utilised, so we can provision the system accordingly,” says Stewart Craine, managing director at VIA. VIA, in partnership with the International Renewable Energy Agency (IRENA), and grant support of the GSMA Mobile for Development Utilities Innovation Fund began building projects in Vanuatu in the South HYDRATHERM’S units have been shown to pro- duce savings of around 70% of total hot-water costs, a significant contributor to electricity bills. And because they use less than a third of the energy of an ordinary geyser, the units qualify for installation in terms of SANS 10400XA and XA2. The company’s full-service solutions are ideal for hotels, laundries, dairies and hospitals, the retail and manufacturing industries, and private homes at a highly competitive level of investment, says managing director Llewellyn Ward. “We aim to minimise payback periods and maximise returns.” The HydraTherm range of high quality, efficient hot water heat pumps includes traditional split pump technology, where an external heat pump is piped to a separate water storage vessel, and an integrated

and enables higher levels of protection and fault tolerance. Galaxy VX offers three flexible operating modes to optimise IT environments, including double conversion mode, eco mode and ECOnversion mode.

C ummins will showcase its latest QSG12 genset at Middle East Electricity (MEE) 2018. This represents a major advantage for Tier 4 Final and Stage IV equipment installations by restoring the envelope size of the QSM11 predecessor used for Tier 3 and Stage IIIA ap- plications. Higher-efficiency air-handling and advanced combustion enable the QSG12 to return to the simplicity of a waste- gated turbocharger, and achieve near-zero emissions without the need for a cooled Exhaust Gas Recirculation (EGR) system. As a result, internal loads on the QSG12 are reduced to free up extra power potential, while heat rejection is lowered by over 40% compared with engines using cooled EGR. To be held at the Dubai World Trade Centre in the UAE from 6 to 8 March 2018, MEE is a perfect platform for Cummins to debut its refreshed product line-up for the power-generation sector. “Our new product range is based on the QSG12 power plant, which has a much higher power density. This means that we now have a true prime-power capability to offer our customers, based on an emissions- optimised and a fuel-optimised variant,” Alok Joshi, Cummins Power Generation, Director, Africa and Middle East explained. “It is a definitive step forward for us, and also a much-improved product. It even has the capability to run parallel with other gensets and grids.” Cummins is a long-time exhibitor at MEE, having had a presence there for the past seven years. “It is a major event for us as it talks to the industry we are in. A lot of diesel genset manufacturers are also present, many of them powered by Cummins. Hence, it is a good platform to launch new products, and to engage with other OEMs.” Joshi said that the genset market is growing in Africa because of the unreliability of power grids and in the Middle East as a result of growing industrialisation. However, prevailing economic and political conditions continue to hamper growth in major markets. “The biggest growth area at the moment is in West Africa, where the focus is on markets such as the Ivory Coast and Senegal.” Commenting on Cummins’ participation at MEE, Joshi said that the company wanted to be perceived as the power solutions provider of choice for a wide range of applications and industries. “It is not just about supplying products, but also about project execution on the ground, and how we are able to support those products throughout the lifecycle of a particular installation,” he concluded. Cummins will showcase its latest Q series gensets at Middle East Electricity 2018 in Dubai.
