We have looked at a Trane 60 ton chiller that possibly has multiple problems and we are working with the factory maintenance people who think that the low flow issues are due to the chiller barrel tubing being restricted. Are hands are somewhat tied due to the fact that the maintenance people want to do as much as they can do. We asked a lot of questions and made some suggestions and then didn't hear back. Recently I ran into one of the powers that be and he said that "Trane" told them that they could not clean the chiller barrel.
Has anyone ever heard of this? Isn't this a standard tube/shell barrel?
