According to ABB, their variable speed drives VSDs save more than energy. Users recognise ABB drives for their ability to run motors at speeds that match the demand of the process. As a result, they will lower the running cost. Yet, in addition to speed control, the drives include functions that make many traditional components […]
Although UK car demand may be falling, the need for parking spaces remains as high as ever. Town centre parking space is at a premium, so car park operators are finding ways to fit cars into smaller spaces. Improving car park ventilation has an important part to play both by improving air quality and saving […]
In 2021, the installation of ABB VSDs to improve energy efficiency provided a payback period of three years. This was acceptable as the savings would continue through the life of the installation. However, recent electricity price increases mean that for Severn Trent Water (STW) VSD payback periods tumble. STW is saving 15,000 kWh annually […]
Anglian Water trials using variable speed drives (VSDs) to control the speed of Archimedes screw pumps, resulted in a three-month energy savings of £26,000 across three wastewater treatment sites. It also helped to reduce wear on the associated belts, drive chains and bearings. Each site uses three Archimedes screw pumps each controlled by a 90 […]
Most motor driven machines benefit from the use of variable speed drives (VSD). In some applications it is from energy savings and in others, improved control of the application. According to ABB, variable torque loads offer the most energy saving and efficiency benefits. This category includes pumps, fans, and air handling units. Pumps VSDs […]
