Kairak condensing units

Hey guys I have never worked with a Kairak condensing system before. Its a big condensing unit with like 3 compressors in it. two walk in coolers and a walk in freezer with some cook line equipment share this ‘rack’ system they call in here in TN. I replaced and expansion valve because of freezing up and low pressure. No luck with the new TXV I checked all 4 evaps in the walk in coolers and they all are running the same. about 0 deg saturation on suction and 90 deg on the head side.404A, Another complaint their having is the walk in freezer with 2 evaps is running about 20 deg. Ive asked my manager if the system could be low on charge he said no the receiver on the condenser is just over40 percent full. Anyone work on these before?
