Evans NPG waterless cooling fluid

[kenmorton]

Anyone had any experience of this stuff? Does it do what it says on the label?

Never used it but read a fair bit on it. Non Propylene Glycol iirc.

Not quite so good as water ethylene glycol mix at removing heat hence the need to circulate it faster, but dosent require a pressurised system to prevent boiling which might be a bonus.

main benefit is cavitation reduction IIRC where it resists forming gas/steam bubbles at the surface of hot spots, meaning that a larger surface area of liquid remains in contact with the hot area transferring heat away more effectively.

The water wetter product does much the same by changing the surface tension of the liquid, again IIRC.
