DOWTHERM SR-1Dowtherm SR-1美国陶氏化学的低温冷媒，冷却液，机器防腐冷却剂
Inhibited Ethylene Glycol-based Heat Transfer Fluid
DOWTHERM* SR-1 heat transfer fluid
is a formulation of 95.5 weight percent
ethylene glycol and a specially designed
package of industrial corrosion
inhibitors. The fluid is dyed fluorescent
pink for leak detection purposes.
Solutions in water provide freeze
protection to below -50°C (-60°F) and
burst protection to below -73°C (-100°F).
Recommended use temperature range:
-50°C (-60°F) to 120°C (250°F).
Suitable applications: closed-loop,
water-based HVAC, process heating
and cooling, food industry applications
within temperature range

NOTE: These figures are examples only and may not be appropriate to your situation. Generally,
for an extended margin of protection, you should select a temperature in this table that is at least
3°C (5°F) lower than the expected lowest ambient temperature. Inhibitor levels should be adjusted
for solutions of less than 30% glycol. Contact Dow for information on specific cases or further
assistance.
