Re: very big problem with refrigerator comp.heat up low cooling in REF portion
You didn't say what refrigerant they are using.
If its 134a, my guess is a blocked filter drier.

Re: very big problem with refrigerator comp.heat up low cooling in REF portion
Is the condenser inside the insulation? If this is so probably you have leaks and low refrigerant charge.
It is impossible to diagnose without more information. You need to install pinch off valves in one refrigerator and measure suction and discharge pressures and temperatures.
And refrigerant too as chemi-cool asked!

Chem, sssshhhhttt, you weren't mentioend in the list of persons to help
It's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.

It's impossible to make anything foolproof because fools are so ingenious...
Don't ever underestimate the power of stupid people when they are in large groups.
Please, don't teach me how to be stupid....
No job is as important as to jeopardize the safety of you or those that you work with.

Re: very big problem with refrigerator comp.heat up low cooling in REF portion
You have 250 units with the same problem.
Definetly a design problem. Let's see, a refrigerant cooled compressor that's overheating.
1. undesized condenser
2. condenser not designed for high ambient (if applicable)
3. return gas temp too high
4. compression ratio too high
5. suction pressure too low
P.S. what does "compressor oil chock" refer too?
