DOWFROST

DOWFROST is a brand of inhibited propylene glycol and ethylene glycol heat transfer fluids manufactured by The Dow Chemical Company (Dow). The product line is engineered for closed-loop, liquid-phase heating and cooling systems where freeze protection, corrosion inhibition, and thermal stability are required. DOWFROST fluids are formulated with a proprietary inhibitor package designed to protect system metals—including steel, copper, aluminum, and solder—against corrosion and scaling over extended service intervals. The brand encompasses several series: standard DOWFROST (propylene glycol), DOWFROST HD (high-concentration propylene glycol for extreme temperature ranges), and DOWCAL 200 (a freeze protectant concentrate). Products are available in concentrations from 25% to 94%, with temperature service ranges typically spanning -50.8°F to 325.4°F (-46°C to 163°C) depending on formulation. Select SKUs carry food-grade certification (NSF/ANSI 61 or similar), making them suitable for applications involving incidental food contact or potable water systems. Fluids are dyed yellow (standard) or blue (food-grade) for leak detection and system identification. 3G Electric stocks 29 SKUs of DOWFROST fluids, including both food-safe and non-food-safe variants, in packaging sizes from 1-gallon containers to 55-gallon drums and 265-gallon totes. The range covers pre-diluted ready-to-use concentrations and concentrates for custom blending. All products are supplied with manufacturer lot traceability and material safety data sheets (SDS). 3G Electric provides logistics support for bulk orders, including drum and tote delivery to industrial facilities, with export documentation for global shipments. For plant engineers and maintenance managers, DOWFROST fluids offer predictable thermal performance, low toxicity (propylene glycol base), and compatibility with standard gasket materials (EPDM, Buna-N). The inhibited formulation reduces the need for frequent inhibitor testing compared to uninhibited glycols. Procurement specialists can select from multiple concentration levels to match specific freeze-point and burst-protection requirements without over-specifying inhibitor levels.

Pertanyaan yang Sering Diajukan

Pertanyaan umum tentang DOWFROST dari 3G Electric.

What is the difference between DOWFROST and DOWFROST HD?

DOWFROST HD is a higher-concentration variant of the standard DOWFROST propylene glycol fluid. While standard DOWFROST is typically supplied at concentrations up to 70%, DOWFROST HD is available at 94% concentration, allowing for custom dilution on-site or use in systems requiring extreme freeze protection. Both series use the same inhibited glycol base, but HD formulations are designed for lower burst temperatures (down to -100°F) and higher thermal stability. The HD series is also dyed yellow, whereas food-grade DOWFROST is blue or clear.

Is DOWFROST food-grade propylene glycol safe for potable water systems?

Select DOWFROST SKUs are labeled as food-safe and carry certifications such as NSF/ANSI 61 for use in potable water systems. These food-grade variants are formulated with propylene glycol that meets USP/NF specifications and are dyed blue or clear for identification. They are suitable for closed-loop systems where incidental contact with drinking water or food products may occur, such as in beverage processing or HVAC systems serving food facilities. Non-food-grade DOWFROST (yellow) should not be used in potable water applications.

What temperature range can DOWFROST heat transfer fluids handle?

DOWFROST fluids are rated for continuous operation from approximately -50.8°F (-46°C) to 325.4°F (163°C), depending on concentration and series. For example, a 30% concentration DOWFROST fluid provides burst protection down to -50.8°F, while higher concentrations extend the lower limit. The upper temperature limit is consistent across most formulations, but prolonged exposure above 325°F may degrade the inhibitor package. Always consult the specific product data sheet for exact temperature limits based on concentration.

Can DOWFROST be mixed with other glycol brands or uninhibited glycol?

Mixing DOWFROST with other glycol brands or uninhibited glycol is not recommended. The inhibitor package in DOWFROST is specifically formulated to protect system metals; mixing can alter the inhibitor balance, reduce corrosion protection, and void the manufacturer's warranty. If system fluid must be topped off, use the same DOWFROST series and concentration. For complete fluid replacement, flush the system thoroughly before introducing new DOWFROST.

What packaging sizes are available for DOWFROST through 3G Electric?

3G Electric stocks DOWFROST fluids in 1-gallon containers, 5-gallon pails, 55-gallon drums, and 265-gallon totes. The 1-gallon size is typically for DOWCAL 200 freeze protectant concentrate. Larger drums and totes are available for both standard DOWFROST and DOWFROST HD, including food-grade variants. Bulk orders can be arranged with logistics support for delivery to industrial sites globally.
