Hello, can someone please tell me the necessary steps to cleaning a chiller barrel? Please assume that the chiller does not have any leaks and that the chiller has been brought offline for service. Thank you.

I’m confused by “Necessary Steps”.

Are you asking about punching tubes?

[klove]

If this is a flooded chiller (water in the tubes), and assuming that the tubes aren't fouled with any hard deposits, brushing the tubes with a rotating nylon bristle brush (wet) is the industry accepted standard. Goodway, Elliott, and Thomas C. Wilson are a few of the companies that offer tube brushing equipment.

If you have tube fouling that requires chemical cleaning, now it's time to call someone proficient in that type work.

If you have a DX chiller (water on the outside of the tubes), it's also time to call someone that is proficient in that type work.

i like to get a box of rags and a mild detergent and just give it a good wipe.:yes:

You’ve asked vague questions and received vague answers. Read the attached manual and get back to us.

A tube brushing machine and a lot of brushes. If scaled after first brushing your going to need scale dissolver. Run this through the machine and keep it a bright yellow color for three or four days, then rent you a tube extractor, a tube expander and buy a bunch of tubes and replace them all because you have burnt holes in all of them with the acid. (DONT DO THIS) I don't think this can be taught on the web. You need to get someone who knows what they are doing, to show you, (probably more than once) how to do it properly.

Ever read the MSDS on hydrochloric acid! You will think twice about messing with acidizing. I mean hydro what I have never heard of it! I highly recommend using spin grit brushes. They can get through some pretty tough stuff where the blue brushed cant budge.

Been a fan of the spin-grit brushes since they came out.

[Marcie]

Thank you very much.

Hello, Thank you for asking who I am and inquiring my motive for being on this forum. I am a Project Engineer and manage design and construction projects for a Government Agency. I have over 10 years of experience providing engineering and management related services to private and Government agencies in the United States. I have a B.S. in Mechanical Engineering and would like to bridge the gap between classroom study and real world practices. Prior to joining my current organization, I served 7 years in the U.S. Army where I had to opportunity to provide humanitarian services in Central America, conduct law enforcement in Japan, and serve in the Southwest Asia during three campaigns of the Gulf War. In closing, I will probably ask questions that seem vague; however, I hope to become more astute in my understanding of HVAC principles, etc. My purpose for joining this forum is to learn and I humbly ask questions from an operations standpoint as I am not qualified to personally do any of the technical work/tasks that I inquire about because I do not have the necessary training.

So did you get what you’re looking for? :lilhelp:

Marcie, you said two things that make people on this site flame up, that being government and project engineer. Most of the time the chiller barrel is part of a closed loop system and generally does not require that much maint. Not that this isn't your problem it is just not that common. Most of the time and what everyone else is talking about is on the condenser side. This is an open loop with water being pumped out to a cooling tower and exposed to atmosphere. Without good chemical treatment this eventually leads to heavy scaling of the tubes and corrosion of the tube sheets. Unless you are responsible for your own chemical treatment, I would recommend the company that does yours or maybe not as it seems they haven't done that good of a job. There are water treatment professionals eagerly waiting on your call. When the guys were requesting more information about yourself, I think they meant for you to completely fill out a membership application. Three threads is real weak here when your asking for advice that could potentially end up costing someone several thousands in damages if done wrong. Then he says but I only did what they said on the web site.-GEO

issue me a purchase order, and i will send two guys to come pull the head and perform proper cleaning, AND let you watch and learn. since this is govt, we will need to follow all safety rules, so give me an idea on tonnage, and access, and ill get er done.

Have you tried to download the IOM from carrier.com? There is alot of great information if you are willing to read the maintenance section.
