Benefits of Inverter Control on Archimedes Screws

Introduction Invented thousands of years ago by the Greek mathematician Archimedes on the occasion of his visit to Egypt. It was used to lift a pool of water to higher levels, usually to transfer water into irrigation channels. It consists of a screw (a helical surface surrounding a central cylindrical shaft) inside a hollow pipe. The Roman screw was also used to dewater mines in Spain. The screw is usually turned by windmill, manual labour, cattle, or by…

Who Says Inverters Dont Save Energy on Archimedes Screws?

Archimedes’ Screws (normally called screws) are widely used by the water industry, usually used for pumping at the inlet of Water Recycling Centres to lift the flow and allowing a subsequent gravity fall through the works. These screws are known for their efficiency, simplicity, ability to handle high suspended solids and capacity to cope with a wide range of flows. Who Says Inverters Don’t save Energy on Archimedes’ Screws? In the past, tests with inverter…

IDS Prevent Imminent Catastrophic Failure of Crusher Drive

After visiting a Tarmac quarry to carry out minor ancillary works, IDS Service Manager, Andrew White, advised the client that the 9-year-old ABB ACS800 drive that control 2 Crushers should be serviced. These drives control Crusher 2 & 4, which are responsible for half of the production at the Tarmac site. Considering this advice, the client asked IDS to provide a quotation for a service and maintenance agreement; and we were soon awarded the contract….

Drives floor energy costs for high rise

A 17-storey office complex has dramatically reduced energy costs by using variable speed drive controlled pumps and fans. A London office complex has saved £15,000 on electricity costs in six months following the installation of 18 ABB variable speed drives (VSDs). The drives, ranging from 5.5 kW to 37 kW, are used on hot water and chilled water pumps as well as air extraction systems. The £48,000 project is expected to pay for itself within…

Variable speed drive cuts risk of sewerage leaks

A pump control system based on an ABB variable speed drive is helping Severn Trent Water protect local homes from the risk of sewerage overflow Severn Trent Water has cut the risk of flooding homes with sewage overflow by installing an ABB variable speed drive (VSD) within a pump control system. The new control system is switched on if the primary programmable logic controller (PLC)-based wash water control system fails, avoiding the need to use…

A-maizing Energy Savings at Grain Processing Plant

Grain processing plants are saving energy with ABB Inverters from IDS. We surveyed the site where we found two dust extract applications. Previously we have found these applications to be high energy consumers, which we were confident we would be able to reduce by using ABB inverters to judiciously reduce the motors’ speed. Energy Savings at Grain Processing Plant Once we had performed a pre-logging exercise to validate the assumptions made the energy saving findings…

Variable speed drives boost hotel water supply while reducing running costs

Daresbury Park Hotel & Spa halves energy use and improves pump system uptime A 53 percent cut in energy use and a significant improvement in the uptime of a hot water pumping systems is the result of installing ABB drives at hotel in Warrington. When the 200-room Daresbury Park Hotel & Spa was acquired by the Britannia Hotel Group in 2015, it soon became apparent that the existing pumping arrangement was in need of an…

Waste company increases productivity by eight percent with ABB drives

ABB drives increase process speed and accuracy, improving productivity and efficiency An eight percent increase in productivity is achieved by installing two ABB variable-speed drives on a waste sorting machine. Wastecycle is a waste reclamation and recycling company with two plants, in Nottingham and Leicester. The company collects and processes 450,000 tonnes of waste each year, over 200,000 tonnes of which is recycled into products such as fuel for power plants. The variable-speed drives (VSDs)…

Working Together to Save Energy in a Laboratory facility – Camfil and IDS

Camfil Farr have a range of energy efficient filters which in combination with ABB inverters allow the same quantity of air flow whilst consuming less power. Working together IDS and Camfil carried out an energy efficiency motor audit and a filter energy survey on a local laboratories’ applications, mostly air handling units. We submitted our findings to Camfil who together with their filter energy survey made a complete offering to the client. The client was…

Drives reduce energy and cut maintenance and ammonia discharge

Anglian Water has cut aerator energy use in half with variable speed drive technology, while removing the threat of blockages A sewage treatment works operated by Anglian Water has halved its aerator energy costs, reduced maintenance and cut ammonia to almost zero levels following the installation of an ABB variable-speed drive. The drive was installed on a 4 kW sewage aerator at the Swallow unmanned treatment works in Lincolnshire. Wayne Barley, northern energy and efficiency engineer for Anglian Water, says: “The vertical rotor…
