GRUNDFOS says older pumps not only consume too much energy, they can also be prone to failure that can adversely affect your business and your maintenance budget. By replacing them with new, energy-efficient pumps, you can get reliable, low-cost pump operation. This is what a large office building in central London did when they replaced obsolete pumps with new, energy- efficient models following a Grundfos Energy Check. The company says the pumps now operate to meet the actual demand, and the new pumps are delivering a saving 318,000 kWh per year after they followed through on recommendations they received having undertaken a Grundfos Energy Check. This amounts to a saving of £30k p.a., a large reduction in CO2 emissions and a payback of just 2.8 years. Grundfos says it is typically able to achieve savings of 30-50% for customers with an Energy Check, as it points the way towards the optimal pump replacement that provide great energy savings. In addition it says customers can achieve reliable operation, reduced downtime and reduced repair costs with the result of greatly improved system reliability. w | www.grundfos.co.uk Burner manufacturer EOGB ENERGY PRODUCTS has announced it has launched a new service to design, develop and integrate bespoke burner controls for commercial heating systems and industrial processes. Working in partnership with customers to understand their production process and specific heat control requirements, EOGB says its engineers can develop a Programmable Logic Controller (PLC) configured to individual requirements. These deliver a range of functions such as sequencing systems to control multiple boilers and furnace control systems to accurately regulate temperature. A graphical Human Machine Interface (HMI) can also be custom-designed to provide sophisticated management and a real-time view of system conditions and operational data, which engineers can access remotely from any internet connected device. t | 01480 477066 w | www.eogb.co.uk/bespoke-burner-controls/ ABB reports it has launched a Lunch ‘n’ Learn training session that shows how water companies can use variable speed drives (VSDs) to make dramatic improvements in their leakage rates. Topics covered include: how VSDs tackle common causes of leakage including elevated supply pressures and water hammer; the role of inbuilt VSD smart functions; the increasing use of cloud-based monitoring techniques in leakage prevention strategies; and how one ABB customer is set to save £4.5 million on repairs and energy costs by 2021 by using VSDs to maintain correct water pressure. The 45-minute session, reducing leakage through the use of variable speed drives, is free to attend and can be delivered at customer premises or an ABB facility.

Pressure on water leaks Working for a major transnational company active in water and waste management as well as energy services, HART DOOR SYSTEMS reports it has installed three Speedor Storms at an in-vessel composting facility capable of processing 60,000 tonnes of kitchen and green garden waste each year. Hart says its Speedor Storms are in demand for high-traffic situations where airborne smells, noise and vermin egress are issues and where high humidity and corrosive atmospheres are also bi-products. The company says Speedor Storm is designed for enhanced productivity, energy efficiency through reduced heat loss and overall environmental control. Main features include a unique guide system offering exceptional wind resistance through a reliable and clean inline drive system complete with integral safety brake and variable speed operation. t | 0191 214 0404 w | www.hartdoors.com Storms good for major company Taking control of combustion efficiency Could your pumps benefit from a health check? Energy, the Environment & Water March 2019 www.pwemag.co.uk Plant & Works Engineering | 39 Following a substantial research project with the aim of reducing exhaust gas emissions and improving the energy efficiency of burners, BABCOCK WANSON has announced the first of its new burners borne of this project: Optimo 2. Optimo 2 is designed as a fully configurable stand alone burner for medium size firetube steam boilers ranging from 2 to 4t/h output. Optimo 2 burners are available from 1500 to 3500kW output for new steam boilers and also as a retrofit solution to upgrade existing boilers to meet enhanced emission requirements. The company says designed with a high-performance combustion head, Optimo 2 emission rates are less than 100mg/Nm3 NOx throughout the firing range when burning natural gas. t | 020 8953 7111 e | info@babcock-wanson.co.uk w | www.babcock-wanson.co.uk Energy efficient burners
