Thermal Wrenches:
Have any of you tried the glycerin-based heat transfer fluid instead
of glycol? We're interested in its purported resistance to heat
degradation, perhaps extending the period between service changes. The
particular mfr and brand we're considering is Whitlam "Solar Hi-Temp.
It's rated for continuous operation up to 180˚ C and resistance to
degradation in short-term exposures up to 232˚C. What's the downside
(other than cost)?
Thanks,
Kelly Keilwitz, P.E.
