Fans End-of-Line (EOL) Functional Test Bench

Full functional fans testing

Extensive functional tests are critical to assure top quality products. Microplan’s EOL test benches will: - Discover all quality issues prior to product shipment, ensuring customer satisfaction - Automatically execute pre-configured End-of-Line tests with minimal operator input, skill or training - Store all test data by boiler barcode for maximum traceability and data analytics - Display explanation of each step of the test and provide instructions with illustrations or video if necessary. Because time is critical, Microplan has developed parallel execution software for maximum efficiency.

List of usual tests:

a) aspiration pressure measurement (with pipes connected to the fan);

b) outlet pressure measurement (with pipes connected to the fan);

c) select a restrictor (nozzle) among 3 different diameters;

d) measurement of the differential pressure across the restriction;

e) flow rate measurement at the outlet of the fan, starting from the measurement of a pressure difference across a flange;

f) measurement of the temperature of the air flow, humidity and ambient temperature;

g) measurement of the rotational speed of the fan, thanks to a laser beam that is reflected by a white point on the fan

h) producing a PWM signal to the fan;

i) reading the fan speed from a Hall sensor signal.
