My freezer inner pipe leakage

[syaful]

any idea to detect leakage. my supervisor ask me to find the leakage. suspected area are on evaporator side. big leakage is no problem but for small leakage it give me a big problem. any one can help or should i throw away the unit before i become crazy guy sitting inside freezer for whole day?

And what is your present method of leak finding?

Feel for the oil deposits

Charge it with nitrogen, and use the old soap and water.

BEST IDEA, Charge it with nitrogen, and use the soap water.

Check at evaporator joints and condenser joints
