The LNG-powered AIDAcosma cruise ship is equipped with Halton’s highly efficient HVAC solutions

With the well-known kissing lips, eyes and waves, the new AIDAcosma cruise ship has the instantly familiar paint scheme of AIDA Cruises. The 183,200-ton ship is the latest addition to the AIDA Cruises fleet and AIDA’s second ship fueled by low-emission liquefied natural gas (LNG). Halton Marine, the leading supplier of marine HVAC, had the privilege of supplying Halton galley hoods, canopies and dampers for AIDAcosma.

About AIDAcosma

AIDAcosma is a Helios class cruise ship built by MEYER WERFT in Paperburg, Germany, for AIDA Cruises. AIDAcosma was delivered to AIDA Cruises on December 21, 2021.

AIDAcosma operates with low-emission liquefied natural gas (LNG) just like her sister AIDAnova, which was the first ship in the world to use this innovative propulsion system. LNG is currently the shipping industry’s most advanced fuel for reducing emissions.

There are a total of 17 restaurants onboard, consisting of buffet restaurants, speciality restaurants and à la carte restaurants. New highlights include an Italian speciality restaurant, Mamma Mia, and Beach House Restaurant.

In late February, AIDAcosma will begin sailing from Hamburg, Germany, on a series of seven-day “metropolis” voyages.

Halton scope of supply

Halton Marine, the leading supplier of marine HVAC, had the privilege of supplying Halton galley hoods, canopies, fire dampers and airflow management dampers for AIDAcosma.

Highly efficient galley ventilation equipment

Halton’s energy-efficient galley ventilation equipment is designed to optimize air volumes inside the galleys, creating comfortable working conditions while minimizing the grease accumulation inside the hoods and ductwork, and improving fire safety and hygienic conditions.

AIDAcosma’s galleys are equipped with Halton’s KWH galley water wash hoods, KFM galley grease hoods, KVM extraction canopies and CCW-M control cabinets.

Thanks to Halton’s KSA Cyclonic Filter technology, the KWH and KFM galley hoods have efficient grease filtration. The KSA cyclonic filters are composed of vertical honeycomb sections. The filters are designed to force the exhaust air to swirl inside, causing the grease particles and other impurities to push against the honeycomb walls, separating them from the exhaust air. This effectively reduces the accumulation of grease inside the exhaust plenums and ductwork.

The KWH galley hoods use Water Wash technology to automatically wash down the grease filters without the need to remove the filters from the hood. The washing cycle, operated by a CCW-M control cabinet, is fully automatic and programmable for use in different operating conditions.

Energy-saving system

The galley hoods installed in the main galley of AIDAcosma are equipped with a M.A.R.V.E.L. demand-based ventilation system. The system adjusts the amount of exhaust airflow and fan speed for each hood as needed by identifying the current status of each cooking appliance in the entire galley. This results in substantial energy savings compared to traditional systems.

Ventilation fire safety

AIDAcosma’s HVAC system is equipped with Halton’s FDB2 A0(A60) fire and gas dampers and FDL A0(A60) fire dampers. The operation of FDB2 and FDL fire dampers is simple: they close when the temperature in the ductwork rises over the threshold limit. Halton’s fire dampers have a fusible link, which is selected according to the desired temperature. Once this temperature is reached, the damper closes.

Airflow management

AIDAcosma’s HVAC system relies partly on the airflow management dampers to regulate the airflow, temperature, air pressure, and safety levels in rooms and spaces serviced by the HVAC system. Halton supplied a wide range of dampers for various airflow management functions, including Halton’s UTG gastight shut-off dampers, as well as UTT, PTS, UKV and HFB airflow management dampers.
