Grasso Compressor fault
Hi
can some one please explain what the following fault is i am experiencing.
Intermediate pressure limiter HP compressor active
Will this effect the compressor ability as we are experiencing problems achieving temperature on a polobed full of brine. They assure me the brine strengh is correct.
The Booster compressor capacity slide value is 88% but the HP compressor only goes to 44% but the compressor is achieving a suction pressure setpoint of 0.55Last edited by Markridgway; 08-05-2014 at 04:08 PM.

Re: Grasso Compressor fault
could you write suction pressure and intermediate and also high pressure .
you wrote your booster compressor running with %88 and second stage compressor running with %44
what is the set point of them ?
what type of compressor you are using .
what is the temperature of them ( suction-intermediate -high).Last edited by mbc; 08-05-2014 at 06:01 PM.

Hi
I do not know the system, but alarm would seem to indicate the inter cooler is out of spec..
Start with re calibrating pressure and temp inputs to control system.
