10.2.- COOLING FANS
The cooling fans must operate correctly to avoid overheating in the static generator
components.
The device has high-speed cooling fans, with an estimated useful life of 40000 hours.
Nevertheless, this useful life can be shortened depending on the conditions of use (temperature, hu-
midity, environmental pollution). In the event that the fans lose their efficiency, the device’s perfor-
mance will deteriorate.
The following symptoms in the static generator behaviour could indicate a deterioration of the fans:
Increase in fan noise.
Increase in temperature of the device under the same environmental conditions and load.
The SVGm regularly indicates a temperature alarm.
The set of fans must be replaced if they have exceeded their useful life or show signs of deterioration.
In such cases, CIRCUTOR will provide a spare part that consists of a set of fans so that the device can
be repaired quickly and easily.
For an installation with devices in parallel, all of the fans must be changed at the same
time.
