ABB drives reduce running costs of air handling unit by 70% At a block of managed business premises in Monmouthshire in 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. With offices, production space and storage facilities, the Castlegate Business Park provides a range of accommodation for offices and light industry. Originally, the fans in the air handling unit were driven directly by the motor via a pulley system. Speed control of the fan was possible by varying the ratio of the drive wheels between the motor and the fan, but this had no effect on the speed of the motor and offered no potential for saving energy. The air handling unit was recently refurbished to meet a lower average demand. A current tenant of the centre had previously been engaged in the manufacture of semiconductors, an activity that generates large amounts of heat and a subsequent demand for air circulation.

As this activity had ceased, the air handling unit now had more capacity than required. Allan McCabe of Kier Managed Services Ltd is the facilities manager for the Castlegate Business Park on behalf of owner Robert Hitchins Ltd.: “I knew of ABB’s reputation but had only used their motors before, not their drives. I decided to ask their local representative to look at the potential for using drives on the installation, both to save money and to reduce the carbon footprint of the building.” 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%. The annual saving of over £6,000 will give a payback time of 16 months. McCabe verified the data himself using the same methods used by ABB and APDS. “We put a data logger on one of the three phases of the motor and got the same result as ABB had demonstrated.

As well as drastically cutting our energy use, it also reduced our carbon footprint.” Go to Energy HomeAir Zone International DBA Air Zone Industries International, Inc. (“AZII”).

While many businesses are searching only for the lowest cost, a more sustainable purchasing strategy takes five areas into account.Is the air handling equipment preassembled, or will it be assembled on site? Will you need special equipment to install your purchase, or is it plug and play? Knowing the answers will help you determine the cost of installation.Does previous air handling unit need to be removed to accommodate the new equipment? Having to demolish and remove older equipment can add to the costs.What are the costs to operate the new air handling unit, and how will the building’s environment impact those costs? While one option may be more expensive than another choice up front, understanding the costs to operate it can make the more expensive equipment a more attractive option in the long run.
