Chem-Frost™

Chem-Frost is a high-performance, bio-based inhibited glycol engineered for superior corrosion resistance within a greater temperature tolerance than standard glycol.

Chem-Frost™ DC

Chem-Frost DC is a high-performance, bio-based inhibited glycol engineered for superior protection for Direct-to-Chip applications in data centers. 

Chem-Frost™ FG

Chem-Frost FG is a high-performance, bio-based inhibited glycol engineered for superior freeze/burst protection and heat transfer in food processing environments. It provides reliable corrosion control in closed-loop heating and cooling systems with a greater temperature tolerance than standard glycol. Chem-Frost FG has been certified by NSF for incidental food contact (HT-1 Rating). The ingredients in Chem-Frost FG are recognized by the FDA as being Generally Regarded As Safe (GRAS) in accordance with 21CFR 184.166, 21CFR 182.6285, and 21CFR 182.3640. The formula incorporates our exclusive OYMI inhibitor, which provides added protection for yellow metals.

Du-Frost is a cost-effective heat transfer solution featuring an industry-standard inhibitor package that minimizes corrosion while providing excellent heat transfer in both hot and chilled systems. Low acute toxicity of propylene glycol makes it a safer-to-use alternative to toxic ethylene glycol.

Du-Frost™

The preferred choice for standard HVAC applications across commercial, institutional, and industrial environments.

Du-Frost™ HD

Designed for high-stress systems, Du-Frost HD features an enhanced inhibitor package that delivers longer fluid life, strong buffering protection, and superior high-temperature performance. 

Du-Frost™ DC

Designed specifically for Direct-to-Chip cooling systems in data centers, Du‑Frost DC is an inhibited glycol solution that helps safeguard critical cooling systems.

Du-Frost™ FG

Du-Frost FG is designed for use in food processing environments, providing reliable corrosion control in closed-loop systems where incidental contact with food products may occur. Du-Frost FG has been certified by NSF (HT-1 Rating.) The ingredients in Du-Frost FG are recognized by the FDA as being Generally Regarded As Safe (GRAS) in accordance with 21CFR 184.166, 21CFR 182.6285, and 21CFR 182.3640. The formula incorporates our exclusive OYMI inhibitor, which provides added protection for yellow metals.
