MSI performs laboratory methods of testing fans for certified aerodynamic performance rating.  Below are examples and a description of our test facility capabilities.

  • Ability to meet guidelines per ANSI/AMCA 210-07 & ANSI/ASHRAE 51-07
  • Drive system/motor up to 150 HP available
  • Variable frequency drive system to accommodate various fan speeds
  • Remote operated throttling device to obtain multiple speed performance curves
  • Facility can accommodate test rigs over 40 feet
  • Up to a 300 channel LabView data acquisition system
  • Direct torque measurement radio frequency telemetry system using strain gauges
  • Full suite of pressure and temperature transducers including Bentley Nevada proximity probes for rotor axial and radial vibration monitoring system
  • Pressure sensing pitot tubes to supplement AMCA standard for low static head fan applications
  • Capability to obtain circumferential and axial velocity components
  • Real-time continuous vibration monitoring employing accelerometers.
