Liebert MiniMate bursting coil
I have a question in regards to a 5ton Liebert MiniMate. It has a hot water heating coil and supplies air for a MRI scan room. We have had the heating coil replaced for times. For some reason the heating coil will burst the top loop and create a big mess. The paper filters are replaced every three months and the RF filters are vacumed every three months as well. The last time it busrt the discharge air temp was 80F. the cooling coil is never frozen and we are at loss. It almost seems that the heating coil is flash freezing internally but I am having a real hard time coming up with a reason. I'm leaning toward the heating valve being bad and water coming in at a real high pressure and vaporizing and the vapor freezing? Any ideas would be great. thanks.
