DOWFROST™ is a premier glycol-based heat transfer fluid, ideal for applications where incidental contact is possible as safety and non-toxicity are critical. 

  • High-Quality Ingredients: Made from food-grade raw materials conforming to FDA CFR 21 and NSF guidelines
  • Pharmaceutical Grade: Utilizes DOW PuraGuard™ Propylene Glycol USP/EP
  • Temperature Protection: Provides freeze protection to below -60° F (-51° C) and burst protection to below -100° F (-73° C), depending on concentration
  • Operating Range: Suitable for temperatures between -50° F to 250° F (-46° C to 120° C)


Engineered for closed-loop HVAC systems, DOWFROST™ HD offers robust performance and protection.

  • Quality Formulation: Made with DOW PuraGuard™ Propylene Glycol USP/EP
  • Wide Temperature Range: Effective between -50º F to 325º F
  • Freeze and Burst Protection: Similar to DOWFROST™, it protects against extreme temperatures
  • Corrosion Inhibitors: Provides additional protection for systems containing copper components
  • Low Toxicity: An environmentally friendly option for sensitive environments like schools and hospitals


For applications requiring long-lasting corrosion protection, particularly for aluminum alloys, DOWCAL™ 200 is the solution.

  • Corrosion Protection: Offers efficient and long-lasting protection, especially for aluminum
  • Low Toxicity: Free of nitrite, borax, and CMR (carcinogenic, mutagenic, and reprotoxic substances)
  • Wide Operating Range: Effective from -50° F to 350° F (-46° C to 121° C)

DOWFROST™ LC 25 Heat Transfer Fluid

Designed for maximum thermal transfer and control, DOWFROST™ LC 25 Heat Transfer Fluid is ideal for cooling equipment.

  • Thermal Stability: Operates efficiently within a temperature range of 0°F (-20°C) to 195°F (90°C)
  • Pumped Refrigerant & Glycol Loop Heat Exchangers: Facilitates effective heat exchange in advanced cooling systems
  • Cost-Effective: Offers a more economical cooling solution compared to air-only systems
  • Bio-Fouling Resistance: Resists and prevents the buildup of biological contaminants

DOWTHERM™ SR-1 Heat Transfer Fluid

A premium formulation, DOWTHERM™ SR-1 is composed of 95.5% ethylene glycol with industrial corrosion inhibitors.

  • Leak Detection: Brightly dyed fluorescent pink for easy identification
  • Temperature Protection: Provides freeze protection down to -60°F (-50°C) and burst protection down to -100°F (-73°C)
  • Corrosion Resistance: Formulated with heavy-duty industrial inhibitor packages that prevent corrosion
  • Wide Operating Range: Suitable for temperatures from -60°F (-50°C) to 250°F (120°C)
