<p class=”MsoNormal”><span lang=”EN-US” style=”mso-ansi-language: EN-US;”>Hello everybody,</span></p>
<p class=”MsoNormal”>We have 2 Starting Air Compressors (Sperre – XA 150) that are aligned in a system to supply starting air for our 3 Wartsila Motors (W50SG).</p>
<p class=”MsoNormal”>In the last year, we replaced some spare parts (kit E) on both compressors. But they still have “High HP pressure” and “High HP temperature”, causing them to “trip”.</p>
<p class=”MsoNormal”>We have already checked the HP check valve, cleaning the HP radiator (it had oil), solenoid (adjustment), etc., and put it into operation. The equipment works for about 2 minutes, reaches 26 bar of pressure in the line and trips by HP Internal High Pressure (32 bar). This is repeated several times.</p>
<p class=”MsoNormal”>Has anyone experienced anything like this?</p>

We are using 2 SAUER compressors for our instrument air with no problems so far 2500 operational hours on them.

Contact Chris he is the US factory rep and is extremely helpful. He will get you an answer. They provide great OEM support. They have solved a number of issues we had after start up. We have 10-50DF engines and 4 compressors with 30K on our engines and have had trouble free luck with the compressors.January 24, 2020 at 5:04 pm #2185AnonymousInactive
Boneil, are your starting air compressors “Sperre”?January 24, 2020 at 6:03 pm #2186AnonymousInactive
They are the same compressors that you have Speere XA 150January 24, 2020 at 6:32 pm #2187AnonymousInactive
Do you never had problems with HP High Pressure or HP Temperature? The HP radiator don’t have oil, same time?January 24, 2020 at 6:52 pm #2188AnonymousInactive
We haven’t any problem like the one you described. Contact Chris and he will help you put this issue in the rear view mirror.
We had some intake valve failure after start up they found a solution replacing all of the intake valves in our 4 compressors and supplying replacement valves that we had in inventory at no cost to us. That’s why I think Chris is your answer.January 24, 2020 at 7:07 pm #2189AnonymousInactive
I contacted Chris and him recommended I talk to Olsen (Sperre’s service specialist). But, I was already talkink to him (Olsen). I’m waiting an answer.January 24, 2020 at 8:08 pm #2190AnonymousInactive
I have used him also and he is full of knowledge. He will get to the bottom of the problem for you.January 24, 2020 at 9:14 pm #2191AnonymousInactive
Ok, thanks a lot for you attention!!!January 25, 2020 at 10:30 am #2192AnonymousInactive
We are using XA 120 in our site, and we used to get this alarm also frequently.
What we noticed is that we had a build up in the coolers and also in the pressure switches.
We had to change the coolers and pressure switches frequently.
Seems that these compressors are only made for start up and they cannot run too long, otherwise it will build up burned lube through the whole system.
Did you change the pressure switches with new ones.January 25, 2020 at 4:27 pm #2193AnonymousInactive
Sure, we already change the pressure switches and we are cleanning the HP radiator every 2 days (oil), approximatelly. We also check (cleannig and adjust) the solenoid valve
Are you still having problems or have you managed to solve them?
