You might want to still look at the inorganic heat-treatment salts too. They are much cheaper, and likely to be easier and cheaper to dispose of. But: you would need to consider recovery from freeze at the very least. And clearly running a heating trace through a pump or valve is tricky. (One answer might to be a drain-back process before shut-down) [Digression] My dad was peripherally involved in a case where an oil tanker full of bitumen froze when the steam heating failed. The conductivity of solid bitumen was not high enough for the steam heating to re-melt it. They ended up cutting the front (tank section) of the ship off and replacing it. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
