Blower & Fan Performance Testing Overview

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.
