The unit allows to study the main features of a rotary screw air compressor. The wheeled bench is equipped with a front panel, on which are placed the devices and all the necessary tools for carrying out the tests.
TRAINING PROGRAM
• System start up
• Inlet and Outlet compression temperatures measurement
• Inlet Compressor air flow rate measurement
• Power and efficiency of a rotary screw compressor
• Air flow rates with unified throttling devices measurements
• Compressor efficiency
• Compressor performance at variable speed.
TECHNICAL SPECIFICATIONS
