Inverter Technology set to save Asphalt Plant in excess of £66k per annum

Industry: Asphalt Plant Applications: Burner Fan & Coater Drum Amount saved each and every year: £66,736 Investment Pay Back Time: Under 12 months An Asphalt plant in the north west of England is predicted to reduce the cost of replacing burnt out motors and improve its plant uptime by fitting inverters to a coater drum motor and a burner fan motor. Inverter Technology set to save Asphalt Plant in excess of £66k per annum Coater…

Switched On Energy Saving

With rising energy costs, is it time to look at using inverters to control motor speed? Energy costs are still rising and are predicted to double in the next fifteen to twenty years. With new legislation, in the form of DCP161, companies who exceed their available capacity levels will be financially penalised paying up to three times higher for the excess than their standard kWh rate. Electric motors play an important role in our everyday…

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…

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…

Do You Know Where Your Next Big Energy Saving is Coming From?

Expanding your electrical infrastructure to support many fan and pump systems can have an impact on the overall system efficiency. This, in turn, could increase the amount of energy you use. Martin Richardson, Water Framework Manager, ABB Limited, shows you where to look to control costs. The need to save energy remains as important as ever – but what happens when all the obvious boxes have been ticked? Let’s consider motor-driven applications. Installing variable speed…

Water Industry System Efficiency

There is a new consideration for water utilities when determining their next move towards using less energy. It is tucked away within something called electrical system efficiency. An electrical system is needed to power pumps and typically comprises a transformer, variable speed drives (VSDs), electric motors, switchgear and cabling. Quite often when specifying such a system, designers simply multiply the catalogue efficiencies for each component to get an overall system efficiency. For example, if each…

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…

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…
