I attend to 5 compressors,GA250 TYPES. One of them is behaving badly wth its persistent trippings indicating high temperature of 110° while accually it had tripped at around 99°-108°. it also tripps when started less than an hour after letting it cool to abt 65°. what could be the problem ..
a) oil is full
b) all electrical components are working
can u furnish me wth acceptable operating parameters of GA250 compressors ..the one I am monitoring is reading as follows this morning 08:58am ( ZIMBABWE)
COMPRESSOR OUTLET TEMP’ = 56°
DP OIL SEPERATOR = 0.38bar
DP AIR FILTER = 0.016bar
OIL INJECTION ELEMENT =3.3bar
ELEMENTS (1) = 87°
ELEMENT. (2) = 103° ( shutdown warning)
COOLING MEDIUM = 29°
OIL SEPERATOR = ( no reading)
OUTLET PRESSURE. = 4.6 bars
Is this an air-cooled unit? Please make double sure that the coolers are clean.
Both the outlet temperature and the element temperature are hot.. so it looks like the coolers are dirty.
Also, check the thermostat valve.
On the other hand, there is quite a big difference between element 1 and element 2.
Please check if there is no blocking of oil flow towards element 2.
All the best,
all coolers are changed , new oil is added, all filters are changed its now running well.
