Hi,
I wanted to get some insights with what might be the reason for high iron content in lubricating oil for ammonia systems. To lay it out straight the iron content is a repitative issue even though after changing the oil, oil filters and fine filter. The upper limit of Iron content is supposed to be 12 ppm, but it is coming to 35 ppm.
Details are as follows;
Compressor - Mycom N 2520LLC
Oil separator - OC2545.
Oil cooling - Thermosiphon Oil cooler.
Condensing temp:- +40 degC
Evaporating Temp:- -40 degC.
Oil Temp on higher side : 59 degC.(6 degC higher, may be due to conatmination)

Thanks.
