Heat Transfer Fluid Glycol in Ross Dependency, Crusader 97842 - Glycols

Glycol-based heat transfer fluids are commonly used for their excellent thermal properties and freeze protection. These fluids, often a mix of water and glycols like ethylene or propylene glycol, efficiently transfer heat in various industrial and HVAC systems. They are valued for their stability, corrosion inhibition, and ability to operate over a wide temperature range.

Size: Typically available in bulk quantities (drums, totes, tankers) or smaller containers (1L to 20L).

Grade: Industrial grade, USP/NF grade, food grade, or inhibited glycol (with corrosion inhibitors).

Viscosity: Varies with type (ethylene glycol: ~16.1 cP at 25°C, propylene glycol: ~40.4 cP at 25°C).

Buoyancy: Lower than water (ethylene glycol: ~1.113 g/cm³, propylene glycol: ~1.036 g/cm³ at 25°C).

Material: Ethylene glycol (EG), propylene glycol (PG), or specialty glycol blends.

Freezing Point: Ethylene glycol: ~-12.9°C (pure), propylene glycol: ~-59°C (pure).

Boiling Point: Ethylene glycol: ~197.3°C, propylene glycol: ~188.2°C.

Thermal Conductivity: Ethylene glycol: ~0.258 W/m·K, propylene glycol: ~0.147 W/m·K at 25°C.

Specific Heat Capacity: Ethylene glycol: ~2.36 J/g·K, propylene glycol: ~2.48 J/g·K at 25°C.

pH: Typically neutral (7.0) for pure glycol, adjusted with inhibitors for industrial use.
