Case Study: Mirae Asset Tower

AuCom soft starters improve system stability at Mirae Asset Tower.

Located only a block from AuCom’s China office in Shanghai, engineers at Mirae Asset Tower recently selected CSXi soft starters for their pumps and fans to protect motors from mechanical and electrical stress.

The project had a range of applications with 32 motors for pumps and fans (22, 30, 37, 40, 55, 60, 90 kW), so having the same starter across all applications was important for training and maintenance.

Sanch and AuCom’s Tommy Ma were able to provide advice to the Mirae Asset Tower site engineers to match the application and load on the pumps and fans with the relevant soft starter.

Safety and reliable performance are mandatory for the customer, but there are benefits for others involved in the installation. AuCom’s soft starters are easy to operate and set up, so installers can have a fast commissioning without a large investment in learning its operation.  The small overall size contributed to a neat and tidy installation.

Key facts:

  • Shanghai Pudong Mirae Asset Tower is a 31 storey office tower in downtown Shanghai, China.
  • It has a column-free design that creates a high efficiency ratio for floor area and a 2.85 m ceiling height.
  • Soft start applications are water pumps (cooling pumps and revolving pumps), fans (cooling fans, exhaust fans, ventilators).
  • AuCom supplied 32 CSXi units, ranging from 22 kW to 90 kW, providing soft start to the pumping stations.

“CSXi soft starters are very compact, which saves a lot of space.  It also provides more stable performance in operation, which is critical.” - Ms Gu Xiaolin, Mirae Asset Tower.
