For high temperature liquid heat transfer - from ambient to 1000 oF - American Hydrotherm offers the only nonflammable, noncorrosive thermal liquid system available that operates at essentially atmospheric pressure - for both endothermic and exothermic reactions. Control Systems are designed for maximum safety - they satisfy all current IRI, FM, NFPA, UL, OHSA requirements (and any special requirements specified by purchaser)
  
This exclusive process lowers the freezing point of an anhydrous salt mixture (freezing point 288 oF to 460 oF) to any desired level down to ambient by dilution with measured quantities. Since circulation is established even before the heat is activated, heat-up to process temperature throughout the entire system remains uniform, eliminating any possibility of thermal shock (broken welds, ruptured tube, leaky tube sheets etc..) or freeze ups.
  
Condensate vaporized from the salt solution during heat-up may be re-condensed in a holding tank for use in diluting the salt during cool down. Ability to control the freezing point of the salt eliminates the need for any jacketed lines.
  
Typical applications include Catalytic Converters and Sulfur Distillation, Organic Oxidation e.g. Phthalic and Maleic Anhydride, Ammonoxidation Reactors, for Acrylonitrile, Alkyl Amine Converters, Organic Chrorinations and Caustic Soda Evaporation, Production of Melamine, Pyridine Base, Methyl Ethyl Ketone and Resorcinol, Nuclear Energy Applications, Waste Heat Recovery, Off-shore Production Platforms.
