Atlas Copco Poor Enclosure Ventilation

Generator enclosure is excessively hot inside, even at moderate load

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Blocked air intake or discharge louvers, Failed enclosure ventilation fan, Incorrect installation clearance, Accumulated dust on radiator

Safety first: High enclosure temperatures can damage components. Allow cooling before opening doors.

Inspect louvers: Ensure intake and discharge louvers are open, unobstructed, and actuators (if motorized) are working.
Check ventilation fan: For sets with separate enclosure fans, verify operation and replace failed motors or relays.
Clean radiator and alternator: Remove dust buildup that restricts airflow.
Verify installation: Confirm that the generator has the clearances specified by Atlas Copco for airflow.
