Problem with a Rotary Screw Compressor

When we turn off the compressor, takes like 7 secons to discharge, then the engine automatically shut down, but at this moment for some reason the coolant comes out of the unit through the inlet valve.

We suspect that have to be a discharche valve or something like that, but we could not found it.

What cuases high a/e discharge fault on ingersol rand air compressor


Dirty coolers are always associated with high discharge temps,always make sure your coolers are clean
compressor oil filters being clogged can also raise your temp n cause the unit to over heat,and on the much bigger machines if the compressor oil pump fails then you will have severe over heating as the oil flow to the cooler is assisted by the pump!!things like regulating pressure should always be adjusted to the machines specs so it doesn't over pressurize n put load on your airend while the engine is at idle.

What does alarm start fault mean on the control panel on a ingersoll rand ssr ep-30 air compressor


I use to start up a 25 HP Ingersol screw type compressor. The only alarms I got were from power spikes which just needed the reset button to be pushed, then the on button - and the low oil sensor would shut it down and give an alarm when the tank was about half way down. They will blow up with no oil so there is a saftey margin on oil level.

I have an ingersoll-rand upright compressor model 2545k10-p, 10 hp, 120 gal, 175psi compressor, and the electric motor will run for about 15-20 seconds and then automatically shut off, and be really hot....


Does the motor rotate the compressor or just set there and hum? How old is this unit? Overload heaters may be to small or unit may be single phaseing. Is there air pressure in the tank when this happens.

My rotary screw air compressor model SSREP100H


It's just too hot. Blow out the radiator weekly. There is an oil temp switch that might need replaced but the radiator is the most common problem with screw compressors. You can check the settings in the control panel, where you turn it on and off. It should be set for a high temp of 185°.

Check if your compressor running in low pressure. If your discharge pressure drop @65psi the result is oil carry over.

1989 Ingersoll-Rand 185 cfm air compressor will not build up air


ITS A POSSIBILITY AND YOU BETTER HOPE ITS NOT SPINNING BECAUSE THE SCREW COMPRESSOR IS LOCKED UP. CHECK THE OIL LEVEL IN THE SUMP AND SEE IF THE ROTOR WILL TURN WHEN NOT RUNNING. TYPICALLY THE DIESEL ENGINE WILL TURN HIGHER RPMS WHEN IT HAS NO DRAG ( NO COMPRESSOR HOOKED UP ). YOU CAN GET THE PARTS FROM INGERSOL RAND OR ANY RENTAL YARD - UNITED, PENSKE, SUNBELT, ETC. THEIR MECHANIC SHOPS ARE USUALLY FOR HIRE AND CAN EVEN INSTALL IT FOR A CHARGE. ALSO MAKE SURE NOTHING BUILT A NEST IN THERE. IF YOU REMOVE THE SCREW, MAKE SURE AND WATCH FOR SHIMS. THOSE SHAFTS NEED TO LINED UP PERFECT TO REDUCE VIBRATION. GOOD LUCK
