Full efficiency ahead: MARENUM as part of cruise ship equipment

Efficient refrigeration technology is needed to keep modern cruise liners on course in terms of heating, ventilation, and air conditioning (HVAC). Chillers play an important role in many aspects of cruise ship equipment, whether for passenger comfort or for the safe, economical, and hygienic operation of the entire ship. As part of the ship technology, they air-condition cabins and public areas, cool food, maintain safety-related systems at the required temperature, and support the management of temperature-controlled onboard applications. Our MARENUM chillers on two 200-meter-long cruise liners are a prime example of this. Four models on each of the two cruise ships guarantee a stable cooling capacity of ten megawatts, thereby contributing to the efficiency of the entire ship technology.

Efficient cruise ship equipment

In addition to reliable cooling performance, the specified energy efficiency ratings were among the factors considered by the customer when selecting ENGIE Refrigeration chillers. This is because energy resources on board are limited, and ship technology with specified energy performance characteristics supports the management of energy-related operating parameters and forms part of the vessel's overall operating concept. Finned tubes designed for seawater resistance and appropriately sized heat exchangers support system operation under specified conditions. A controllable 3-way valve guarantees trouble-free operation at seawater temperatures from -2 to 36 degrees Celsius. MARENUM also impresses with a well-thought-out maintenance concept that promises operational reliability and a long service life. This makes our chiller a key element of the refrigeration and air-conditioning equipment used on cruise ships.
