Case Studies

Beijing Yanshan


The fan was running at full speed continuously, regardless of conditions. Beijing Yanshan decided to implement speed control to avoid wasting energy.

The Solution

The Company investigated several speed control technologies (including VFDs and Eddy Current Drives) before settling on MagnaDrive’s 20.5 ASD

The Results

  • The primary benefit that Beijing Yanshan expected was energy savings through speed reduction.
  • This benefit was realized very quickly: annual energy savings through use of the ASD was approximately $50,000
  • As a bonus, the customer also reported decreased vibration and noise – this has reduced maintenance downtime for the motor and fan.


Adjustable Speed Drive and magnetic coupling solutions from MagnaDrive are ideal for a wide range of applications.
