Refrigeration Compressor Fault Simulator | PolarX – 572
The Refrigeration Compressor Fault Simulator PolarX – 572 trains students to detect electrical issues in refrigeration systems using a real refrigerant compressor from practice (approx. 850W). This Refrigeration Compressor Fault Simulator enables simulation of faults including motor coil fracture, operating capacitor short circuit, welded start-up relay contacts, and condenser or evaporator fan faults. Electrical components, including start-up capacitor, operating capacitor, and bimetallic overheat protection, are wired and clearly visible, monitored by 5 Type-k temperature sensors. Optional LABVIEW-based DAQ software supports automated data measurement.
The Refrigeration Compressor Fault Simulator PolarX – 572 helps students detect electrical issues in refrigeration systems through a thorough understanding of component design, operation, and circuit diagrams. This Refrigeration Compressor Fault Simulator features a real refrigerant compressor from practice with all electrical parts wired and clearly visible.
Product Overview A thorough understanding of the design and operation of the various electrical components, along with the ability to read circuit diagrams, is necessary to detect electrical issues in refrigeration systems. This Refrigeration Compressor Fault Simulator assists students in learning this information. The electrical parts needed to start and run a refrigerant compressor are already wired and easily visible on a panel.
The necessary start-up relay and capacitor for the motor are examined. Circuit breakers and other common protection devices are also organized in an easily visible manner. It is possible to simulate various faults, such as a motor coil fracture, a short circuit in the operational capacitor, or welded contacts in the start-up relay. Voltages and resistances can be tested using a multimeter for defect indication (not provided).
