Marine Zeotropic Refrigerants in Malabo - Refrigeration Systems

Marine zeotropic refrigerants are blends of different refrigerants with varying boiling points, used in marine refrigeration systems. These refrigerants exhibit temperature glide during phase change, improving system efficiency. They are designed to meet environmental regulations while ensuring reliable performance in marine applications.

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.
