The water supply to the container usually uses fresh water which is cooled by sea water. The intended incoming temperature is thus approximately 35°C. The water-cooled condensers of the container are resistant to sea water which would theoretically allow operation with sea water, but this method is usually avoided due to the risk of corrosion.
The maximum cooling water flow is approximately 30 l/min at a pressure loss of around 1.2 bar. The maximum return air temperature when cooling bananas is then approximately 45°C with a heat yield of approximately 24 kW.
