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.
