Heat Transfer Liquid PROPYLENE Glycol

Heat Transfer Liquid – Propylene Glycol

A high-performance, industrial-grade heat transfer fluid formulated from USP/technical-grade propylene glycol, engineered for reliable thermal management across HVAC, refrigeration, solar thermal, food & beverage processing, and industrial cooling/heating systems.

Key Features:

• Efficient Heat Transfer – Excellent thermal conductivity and specific heat capacity ensure consistent, efficient heat exchange across a wide operating temperature range.
• Freeze & Burst Protection – Effectively lowers the freezing point of water-based systems, protecting pipes, coils, and equipment from freeze damage in cold climates.
• Corrosion Inhibition – Formulated with corrosion inhibitors to protect metal components (copper, aluminum, steel) from rust and scale buildup, extending system life.
• Low Toxicity – Propylene glycol is non-toxic and safer than ethylene glycol alternatives, making it ideal for applications where incidental food contact or environmental sensitivity is a concern.
• Wide Operating Range – Maintains stable performance from sub-zero temperatures up to elevated operating temperatures without significant degradation.
• Long Service Life – Resistant to oxidation and thermal breakdown, reducing the frequency of fluid replacement and system maintenance.

Glycol characteristic is to transfer heat from one place to other, due to that water-miscible glycol based coolant frequently used in heat transfer and cooling applications. Addition of Propylene Glycol in water enhances heat transfer parameters than water.

This Inhibited  Propylene glycol heat transfer fluid has an operating temperature range of -50°F to 325°F; with fluid freeze protection to below -60°F, and system burst protection to below -100°F. 

 

This fluid is specially formulated for HVAC systems to keep pipes free of corrosion without fouling.

 

 

This fluid is recommended for use in applications where low acute oral toxicity is important or where incidental contact with drinking water is possible.
