Glycol Heat Transfer Fluid

6/7/2016

1 Comment

 
  • Choice of Dowtherm SR-1 for Industrial Grade and Dowfrost for Food Grade
  • Corrosive
    • ​All salts are very corrosive
    • Long term protection is impossible even with corrosion inhibitors
    • Glycols (without corrosion inhibitors) are corrosive to most metals
    • Oxidize to form acids --> low pH --> acidic pH is corrosive
    • Must use correct type of corrosion inhibitor technology
    • Corrosion damage can occur in less than 2 years
    • Worse for high temperatures and high exposure to air or dissolved O2
  • Dow heat transfer fluids are properly formulated with corrosion inhibitors and pH buffers which:
    • Passivate metal surfaces  prevent corrosion
    • Neutralize degradation compounds  prevent pH drop
    • Thermoxidatively stable provide long term protection
