The RSW concept has been developed to meet tomorrow’s demands for top-quality fish and versatility. The concept has been designed for installation aboard fishing vessels, where the most important single factor affecting the quality of fish is the post-catch refrigeration and temperature control processes.

Benefits:

• The quality of the fish on landing
• High COP value, which means lower operation costs
• Lower cleaning and maintenance costs
• Faster installation times

Our freezing cascade plants use a CO₂ refrigerant on the low-temperature side and a NH3 refrigerant on the high-temperature side. Compared to a normal plant (NH3 direct), the freezing capacity is 25% higher within the same floor space.

Benefits:

• Up to 30% capacity increase in the freezing plant
• 25% reduction in the required space for freezers
• Faster defrosting at lower temperature
• Operating with positive pressure, which ensures that air in the system is not an issue
• Wet return lines are reduced to half the diameter in comparison with ammonia / R22
• Coefficient of performance (COP) is increasing up to 15% at evaporation temperature of -45°C
• The increased COP gives savings in diesel and generator capacity – up to 10% saving in power
• In case of leakage, the cargo will not be affected
• CO₂ is a safe, natural and future proven refrigerant
• CO₂ gives a constant freezing capacity output in everyday operation
