Refilling Eisbaer 140

Hello,
I've had my Eisbaer 140 a little more than a year now and when Argus Monitor maximises the pump speed control it gurgles so I think it's time to top-up with some fresh coolant. Since I'm only toppping up, is it okay to use demin water only (I have access to industrial quantities of the stuff...) or will it be the case that the anti-microbal components will also have evaporated too? Or should I completely drain and refill with a recommended product?

On a different theme, is there such a thing on the market as a quick-fit 45 or 90 degree elbow that I can join in line with the quick-fit fittings of the Eisbaer AIO? Seems like a better place to break in to the system rather than have to remove the pump from the CPU in order to raise the filling port to the highest point for proper priming

My system is very cramped and would benfit having an elbow here:

Also, how "water solid" should it be, i.e. if I leave no room for expansion at all, then when the coolant heats the system will then become pressurised quickly. Typically how much volume should I leave as air (i.e space for the water to expand in to)

Hi there,

Yes i would definietly recommend this. After you dranin the AIO you can fill the system with distilled water and some anti corrosion fluid.

Well i really dont know but we do not have such a connection. I never saw something like this before.

You can fill the system completely. An amount of water will disappear after a while because of diffusion.

Metropolis,
Many thanks for your advice,

What particular product would you recommend? As I understand the subject, automotive antifreeze (be that ethylene gylcol or "OAT" etc) isn't appropriate for this application. CKC apparently contains the required chemicals, though obviously already mixed with demin water.

I was assuming the quickfit might be universal and therefore I might have options here:

Okay, thanks.

You are very welcome,

I would recommend to use distilled water like CKC together with some anti corrosion fluid. You can use also antifreeze.

No, the quick coupling connections are not universal ( there might be some products on the market which are universial but we dont have something like this) .

With the above information in mind, I am cautious so as not to add in the wrong chemicals and cause a problem. Can you advise the composition of the metal components of the Eisbaer 140 (Aluminium, Brass, copper).

I know anti-corrosion/bio-cide should be used, but generically speaking it would seem anything containing Copper(II) sulphate or chlorine/chloride should be avoided with aluminium components.

(perhaps CKC does contain Copper(II) sulphate??).

I don't want to or need to use a colourful extravagant solution, just whatever is required for reliable operation without corrosion or fungal buildup

Eisbaer AIOs have pure copper radiators with brass threads. We dont use Aluminium on end customer parts.
