Marine Zeotropic Refrigerants are blends of two or more components with varying boiling points, leading to temperature glide during phase change. Common examples include R-407C and R-410A.
Key Specifications:
- Size: Typically stored in cylinders ranging from 10 kg to 1,000 kg.
- Grade: Industrial or commercial purity (99.5%+).
- Viscosity: Varies by blend (e.g., R-407C: ~0.013 cP at 25°C).
- Buoyancy: Heavier than air (density ~1.2–1.5 kg/m³ at STP).
- Material Compatibility: Compatible with POE oils, steel, copper, and aluminum; avoid elastomers like natural rubber.
Refrigeration Systems:
- Size: Ranges from small (1–10 kW) to large industrial systems (100+ kW).
- Grade: ASHRAE/ANSI standards compliant.
- Viscosity (Oil): POE lubricants (ISO VG 32–220).
- Buoyancy (Leak Behavior): Refrigerant tends to settle in low-lying areas.
- Material: Systems use copper tubing, steel piping, and aluminum heat exchangers.
