Reduces costs by 70%
February 1st 2008

At a block of managed business premises in Monmouthshire, Wales, the installation of two ABB variable speed drives has reduced the running cost of the air handling unit from £180 to just £50 a week. This is set to save over £6,000 annually, reducing CO2 emissions by 12 tonnes per year. ABB Drives Alliance partner APDS installed two new ABB drives, a 22kW drive on the supply fan and a 15kW drive on the air extract fan.

Running the unit according to demand and taking account of the reduced occupancy, the ABB drives have brought energy costs down by 70%.
