CS4 coolant
- Thread starter Poke-E

In for the answer as well. I saw a video somewhere where the guy used automotive coolant and cut it with distilled water until he got a neutral ph. Don’t know if this is the best recommendation or not if using an actual coolant?

Any extended life pre mixed automotive coolant or distilled water with water wetter works. Automotive stuff will probably give you better anti corrosive properties.

When it comes to cooling water for long term use, you need to be concerned about a few particular issues.
pH, TDS and anticorrosive chems. Automotive antifreeze mixed at the proper dilution rate provides all three with no need for testing.
If you use distilled or RODI water and a whetter only, you risk a high/low pH and a lack of TDS.
It's unknown if the cheap chinesium PC coolant whetters have any anticorrosives at all so be aware.
Total Dissolved Solids (TDS) is essential to your system and the lack of them will cause erosion of the water jacket metals as the ions from the water jacket will be removed to satisfy the missing solids in your cooling water. This is different from corrosion.
I've spoken about heat transfer a few times here but here's a quote to help you understand the concept better:
"In thermodynamics, the heat transfer coefficient or film coefficient, or film effectiveness, is the proportionality constant between the heat flux and the thermodynamic driving force for the flow of heat (i.e., the temperature difference, ΔT)."
We casually express this as Delta T and at the core, it means the differential temperature of the cooling water before it enters the head and after heat transfer has happened and the temperature of the cooling water as it exits.
We know from a billion of automobiles and trucks worldwide that a ΔT of 20°F is sufficient to cool the ICE and keep them running at temp indefinitely (less fuel, oil and wear).
So it is with our water cooled compressors, cold faucet water, ice, cooling etc are not needed to cool the head. Just water that is room temperature is capable of a 20° ΔT.

Thought that I read that Zerex G48 anti freeze mix 70/30 with distilled water. This is supposed to give the neutral pH recommended.
No 1st hand experience, not having a CS4

This is true of all antifreeze as far as I know.
Keep in mind that using mixed antifreeze with less water than recommended will result in poorer heat transfer.

Welllllll... It says to us PH neutral coolant. That seems to be not so easy to find unless you want to buy a $300 5 gallon bucket of it.Like the correct grease to use in it ain't that covered in that units manual ?. Lol.

Can't you mix baking soda (base) or a acid and just the pH strips ?
Seemed this was 4th grade science?

I think there's kits at garden centers , pool supplies, Amazon ...

Anyone know what the pH is for Zerex G48 premix (do not add water) ?
Still waiting on my ordered CS4

This compressor is not made out of exotic metals, just grab some pre-mixed universal coolant.

": For the first use, it must be filled with 500ml of neutral distilled water (can not contain impurities such as minerals )or antifreeze ( PH is about 7)."
Quality premix coolant should do . At least it would for me ..lol

The pump & compressor housing is made of aluminum so you probably want an anti freeze that is formulated for aluminum. Maybe contact GXPump & ask for recommendations.
