Using ABB variable speed drives is helping industrial and commercial HVAC applications saving energy and money. The way motors consume power (cube law) means that a 20% drop in speed of centrifugal pumps and fans can save as much as 50% in energy. Electric motors installed in new buildings are optimised energy-saving. This is not […]
University demonstrates massive energy savings still available by installing VSDs. Despite being promoted for energy saving for over thirty years, huge opportunities still exist for retrofitting inverter drives in building services. In a recent example, installing ABB drives at the university of Leeds reduced carbon emissions by over 809 tonnes p.a. and […]
Installing ABB drives and controls at a problematic biomass steam generating plan in Brazil has resulted in improved productivity, higher sales and lower energy costs. The Brazil plant produces saturated steam in two low pressure boilers. However, the outdated controls were inefficient and prone to frequent disruption and downtime, resulting in lost revenue. The […]
Finding energy savings may mean replacing healthy motors. Most new equipment using electric motors of any size is optimised for energy consumption. However, there are still opportunities for reducing energy use in older motors, even if they are operating healthily. You just need to look for them. Clearly the larger the motor, […]
For 2017, ABB has updated its checklist for building services consultants. When specifying VSDs, ABB Drives urges consultants to review their requirements and ensure the selected drives meet them. According to ABB, initial purchasing represents only about 20% of total cost of ownership of an HVAC system the balance being the operating and running […]
