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 or map
- 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.
