depends on the type of scale you have HCL works on only CA, MG or silica deposits take a disperstant I think contact a good water treatment company such as Garratt Callahan

nucalgon makes various HVAC cleaners including scale removers designed for your application. Their calcisolve is outstanding stuff but very strong. it is less damaging then straight muiratic acid, but that is it's main ingredient.
I am maintaining some compression molders which cool via internal tubing which uses plain city water to cool. I just got the ownership of this equipment and in reading over the literature they recommend preventative maiteneance of cleaning the colils to remove scale and rust, of course this was never done under the previous owner. Any suggestions would help, they recommend boiler treater solution, but the more green the better. I had a suggestion of a 25% muiratic acid solution, but I am open to anything Thanks!
Also depends on the tubes themselves and what they are made of.. obviously aluminum tubing would require much different chemicals than copper tubing.. and yes I have seen aluminum in cooling towers and no I didnt understand it either. also is it growth as in algae or is it hardness as in calcium that needs cleaned.. algae you could use a chlorinating type , but if its a pass through system from city water hopefully you have a large budget for the bill. depends where you are I guess... if nothing else is the city water being utilized after the tower..? if not that could be used for countless things as well. as an idea after the fact. or even better yet, a closed loop would be the way to go, unless the water is way cheap , etc etc...

Just a small compression molder with a loop of tubing carrying heat away from the press face, actually might be non-potable semi-treated river water, I need to check in on that.
If river water it might not be very hard water. You need to know what the tube metal is too. If stainless you shouldn't use muratic (hydrochloric) acid, and 25% Muratic is way too strong....try 10% or less. Can you recirculate the acid thru it with a little heat, say 140-150F? You could just put a little acid in and see what kind of reaction you get, whether it does any cleaning, etc. What kind of volume to fill the tubing?
Why not just use vinegar ??
But it is most important to know the particular metal..A good balance is needed between durability and efficiency...
I've heard that the Denver water is soft, non-acidic, maybe the only place in you nation with "easy on the plumbing" water...

Well I have ran boilers for many years,,,first use a water softener(softened water=less deposits),,,watch how much makeup water is used,flush lowest point in system,under light load,,,and most importantly,have a good supplyer ofchemical,,as Freemont,Nalco etc,,and conduct dayly testing on water from system,and adjust chemicals as needed,,,,,,,,,,BL
