Marine glycol solutions are specialized fluids used in marine refrigeration systems to prevent freezing and corrosion. These solutions are typically propylene or ethylene glycol-based, ensuring efficient heat transfer and system protection. They are essential for maintaining optimal performance in harsh marine environments.
Marine Glycol Solutions for Refrigeration Systems typically include the following specifications:
Size: Available in various container sizes, commonly 5-gallon pails, 55-gallon drums, or bulk quantities.
Grade: Propylene glycol (PG) or ethylene glycol (EG), with PG being preferred for food-grade applications due to lower toxicity.
Viscosity: Varies with concentration; typically 40-60 cP at 20°C for a 50% glycol-water mixture.
Buoyancy: Slightly denser than water (1.03-1.08 g/cm³ for 50% glycol solutions).
Material: Corrosion-inhibited glycol blends compatible with copper, steel, and aluminum components.
Freeze Point: Adjustable based on concentration; -34°C (-29°F) for 50% PG, -37°C (-35°F) for 50% EG.
Boiling Point: Elevated with glycol content; ~106°C (223°F) for 50% PG, ~108°C (226°F) for 50% EG.
pH Level: Typically maintained between 7.5-10.5 to prevent corrosion.
Thermal Conductivity: Lower than water (~0.34 W/m·K for 50% glycol solutions).
Compatibility: Suitable for marine chiller units, secondary refrigeration loops, and heat exchangers.
