Dowfrost HD

Dowfrost™ HD is formulated with 94.0% propylene glycol and an advanced industrial corrosion inhibitors. Dyed fluorescent yellow for leak detection, provides freeze protection down to -50°C (-60°F) and burst protection to -73°C (-100°F) when mixed with water. Low toxicity and environmentally safe, Dowtherm™ HD is widely used in industries where equipment longevity is crucial.

Key Features:

• Temperature Range: -50°C to 120°C
• High Purity: Made with a pharmaceutical-grade monopropylene glycol, DOW PuraGuard™ Propylene Glycol USP/EP, with a purity of 99.8%+.
• Fluorescent Dye: Yellow-green color for leak detection and system maintenance 
• Corrosion Inhibitors: Contains durable, food-safe industrial corrosion inhibitors, maximizing fluid and equipment life with metals commonly found in HVAC and industrial systems, such as stainless steel, copper, and aluminum.
• Low Toxicity: Safe for use in environments where reduced toxicity and environmental friendliness are important, such as food and pharmaceutical industries.
• Competitors often use recycled, industrial-grade, or bio-renewable glycols, which may not meet USP specifications. Dowtherm™ HD provides superior stability and reliability.

Applications:

• HVAC Systems: ideal for use in heating, ventilation, and air conditioning systems
• Food and Beverage Processing:Used in indirect cooling systems where low toxicity and compliance with safety standards are critical such as refrigeration, freezing, and cold storage
• Pharmaceutical Industry: Environments requiring precise temperature control, such as fermentation, cooling, or storage of sensitive materials.
