Tony. I suspect its revving stronger now since its not under load.

The throttle should be controlled by a pressure switch / unloader, that throttles up the engine when there is demand for air, and throttles it back down when it reaches the normal cut out.

This is something a diesel mechanic should be able to work on for you. Impossible from a desk here in North America.

Cheers,

Bill

Hi Greg... I was not able to find any info about your IR air compressor.

Is it a 15 HP, two stage compressor? If so, or even if not, where is the PRV located that keeps blowing open?

What is the pressure showing on the tank gauge when the PRV blows open?

Please post your info as a comment here so I can follow the thread.

Thanks,

Bill

IR compressor, 15hp blowing buss fuses

IR compressor, 15hp, 200 volt 3 phase, twin head compressor.

50 amp fuses in electrical disconnect are blowing occassionally and are very hot to touch.

Not always the same fuse. Not blowing on startup, but during normal running...loading is equal on all phases. Motor is hot to touch, but not excessive.

Wire is sized above spec. Thermal switch is sized above spec. Electrical disconnect is rated 60 amp....should we perhaps be using a higher rated electrical disconnect (100 amp)??
