Hello,

I'm doing an extreme version of the Drewmeister AC-X, but pressure testing my rig with regular water has scared me half to death about 3 times now so my attention is turning to dielectric coolants. I understand that fluorinert is 300 a gallon along with Exxon Coolanol, Fluid Xp is 100 a gallon, and PC ICE is like 80 a gallon, but, the thing is, I need 2 gallons, and if I have another spill I can't be forking out 200 dollars or more everytime. Besides, I read PC ICE is really just conductance free, not really dielectric, and Fluid XP I have found few reviews on. Not only that, but I think slipperiness of the coolant is also another consideration along with the fact I am using a sealant on my heat exchanger, and the coolant must be inert with respect to the strength of the sealant.

Searches for a cheaper less commercial alternative have turned up mineral oil which I have read spoils overtime and only reaches -20c im looking a -50c or more, and the synthetic blends and full synthetics I have had trouble finding. Besides, I'm not sure with the viscosity of these fluids that they are even a viable option. Another cheap alternative I came up with was brake fluid or silicone brake fluid which comes in a variety of dots, but I also have concerns about pump heat, life and compatibility with my white water les especially since I am determined to get my hands on an Iwake RD-30. I tried ask a scientist the website but they said my question was outside the scope of thier site prolly cause I could make some money with the ans

So, I'm kind of at a loss at this point

Any help anyone could provide would be greatly appreciated.
