Evaporator coil tubes collapsing in large freezer
Evaporator coil tubes collapsing in large freezer
(OP)
Hope someone can help me. I am an engineer at a plant that manufactures food flavorings. Our large inside freezer 3000 sq ft, uses two evap coils 3' x 12' by 2' thick. They were installed in 1999. The coil has failed many of the copper tubes have collapsed. The maunfactur Coil Company Inc has never heard of this nor have the repair folks. Looking for reasons for failure, it is not ice builup the tubes have collapsed as if from vacuum, they have not been smashed.Maybe someone cam give me some insight. The coils are model DX58-H6-14389-SCA-R. Thanks John.

What is the temperature of the room in which the evaporator is located?

Bad heater can certainly contribute to the incomplete defrost but thats usually easy to identify with an Amprobe. Cold lubricant both harder to identify and more difficult to address...as are the tubes which now have a cross section like a cookie with a bite out of it.
Did this thing go through a change in refrigerant by any chance?

what can i do to prevent this, there are two coils in the freezer the other is keeping it going. the freezer is 140ft x 40 ft by 10ft high, thanks again, John

I'm just south of the KY border. That's a bad situation up there. Good luck!
