Upon inspection, the existing belt driven fan had suffered catastrophic damage due to the shaft shearing completely from the impeller. More critically, with the 9m3/s AHU being completely out of service, this prevented the supply of any heated air across the main store shopping aisles, signiﬁcantly impacting customer and staff comfort levels.
Due to the size of the existing fan, a like for like replacement would require a split casing and involve costly lifting equipment to allow the fan to be assembled in position. The innovative solution was to replace the existing belt driven fan and motor with a FAN WALL of ultra-high efficiency, direct drive EC. plug fans.
Improved Reliability: EC fans are direct driven which means no belts and pulleys
Effective Redundancy: If one of the four EC fans were to fail, the remaining fans can continue to operate to provide airflow
Future Proofing: Eliminates multiple points of failure such as belts, pulleys, and bearings becoming faulty
Reduced Maintenance: Lightweight and compact for easier manoeuvrability and reduced maintenance requirements.
