Tests and performances

Testing bench and performance check

Involved in its quality process and beyond the systematic mechanical tests, NEU-JKF Fevi provides its customers with the means to verify and validate the proposed aeraulic solutions but also to confirm the expected contractual performances.

The test bench in some words

Tests and measurements

# Fan tests

# Simulation bench for system pressure losses

# Measuring unit

# Sound level measurements

Tests and controls

# SCHENCK vibration analysis (pre-balanced rotors)
# COFREND penetrant testing Level II
# Temperature rise control of bearings
# Acoustic performance
# Sealing (shaft passage & envelope welds)
# Customer reception
# Additional tests on request (US, radio, magneto ..)

The test bench ensures the end of the fan manufacturing process. It guarantees the contractual data.
