If it is an older chiller I would suggest you budget money to the replace the unit. If it is relatively new (10 years) the repairs should solve the problem. If properly repaired there is no reason this problem should repeat.
Hope this helps. Tom
we have in the hospital carrier chillar type but after 6years we find coil leaking and when the maintance people try to remove the compressor they found water mixed with gas comeing when they take the compressor out but what happened after that they repair the compressor and repair the coil my question is to know if this problem will come agian mean we have to replace the coil or mantaining it enought and should the water going (in) to the chiller should be treated or not?
