Wartsila’s User Group Forums General Starting Air Compressors (Sperre – XA 150) Reply To: Starting Air Compressors (Sperre – XA 150)


Dear Emir,

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.
