Case Studies

Grand Hyatt Hotel


The Grand Hyatt experienced a number of complaints that water pressure on the upper floors (during periods of high occupancy) was insufficient.

The Solution

  • The Grand Hyatt decided to install MagnaDrive’s 10.5 Adjustable Speed Drive in order to regulate water pressure and flow so that it could be tailored to occupancy levels and guest demand
  • The hotel had experimented with VFDs in the past but experienced problems.

The Results

  • The ASDs provide all rooms with required water pressure and flow regardless of occupancy level.
  • Water pressure is maintained in an even, consistent manner
  • System vibration levels were reduced by 70%
  • The Hotel saved approximately $11,000 in energy and maintenance costs per ASD every year.


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