Better as coolant, water or water/ethylene glycol mix? urgent!
Better as coolant, water or water/ethylene glycol mix? urgent!
(OP)
Hi all
I am working on a guarded heat plate that is cooled with a heat exchanger type arrangement through the cold plates above and below the test specimens.
My question is this - I have to choose a coolant, the cooling unit has text on the side that recommends either water or water and ethylene glycol in a 60/40 mix. This coolant is to be at constant 15 degrees celsius. Which option would be best? Should I add a surfactant if I use water?
Initially I was going to test both, the water then the mixture but the existing test apparatus is quite fragile and I am afraid that running many tests will break it and I don't have a lot of time on the apparatus. Any advice or alternatives will be greatly appreciated and I'm sorry if this is very long-winded, it's my first post.
I would appreciate some quick responses as I have to make a decision tomorrow!

RE: Better as coolant, water or water/ethylene glycol mix? urgent!
On the other hand, you mentioned broken test apparatus. Consider the implications of a water leak versus an ethylene glycol leak.

Thanks to everyone who responded. I have went with water on the basis of the advice given, thanks again for the tips!
