💡 Why do heavy duty APU cooling units fail prematurely under thermal stress?
Casual inspections reveal material shortcuts right out of the shipping crate
Poor metallurgy in lower grade housings oxidizes from repeated freeze thaw cycles
Misaligned shaft bearings wear faster when mismatched to OEM torque specs
Inadequate seal face hardness allows abrasive coolant particles to score the rotor
Substandard impeller casting unbalances the hydraulic load during peak RPM swings
