ABB guide to VSDs in retail environments. According to the Carbon Trust, the retail sector accounts for about seven percent of the UK’s carbon emissions, with the biggest energy users being refrigeration and heating, ventilation and air conditioning (HVAC). Refrigeration accounts for about 40 percent of energy consumption, but for certain retailers […]
ABB drives reduce chiller compressor running costs by £6k p.a. Poole’s Pies of Wigan, in the UK, employs 100 staff and can produce 200,000 meat pies a day, as well as 80,000 other puff pastry products. Since refrigeration systems typically run 24 hours, most fan and pump applications are potential […]
An Improved Approach for Connecting VSDs and Electric Motors When electric motors are connected with Variable Speed Drives, some precautions must be taken. Motor cable length can create short time over-voltage at the motor terminal. This phenomenon results in premature ageing of the motor winding insulation, and, if not properly designed, will lead to […]
A US based maker of custom ventilation and refrigeration systems for potato and onion storage uses ABB’s advanced drive technologies are used to provide precise, on-site and remote environmental control that helps ensure vegetable quality and reduce mass loss (shrinkage), while saving energy. Each potato and onion variety has its own temperature […]
In a wastewater treatment plant, spiral pump gearbox failures occurred repeatedly in the sludge recirculation pumping station, causing the site to use submersible pumps to maintain the flow. The introduction of vibration monitoring was key to preventing further wastewater pump failures. The maximum service life of a gearbox is about two and a half […]
