New cooling technology available for passenger ships

The GadCooler is a new energy efficient cooler for ships. Based on absorption technology it uses waste heat to provide air conditioning cooling and refrigeration for all types of ships. It can handle all or a part of the cooling needs onboard. GadCooler provides major fuel savings for shipowners.

The system uses non-toxic fluids, is practically maintenance-free and can be installed during a normal service docking. The return on investment is short making GadCooler an obvious choice for shipowners when looking for further savings in operational costs.

The GadCooler has been developed by Gadlab Engineering, with patent pending. Heat in the form of steam, rest heat from the engine cooling water or heat from other sources such as boilers is utilized to provide chilled water using a non-toxic absorption fluid as transfer media, replacing the need for onboard cooling compressor capacity.

The system has been successfully applied onboard Eckero Line's cruise ferry Finlandia providing remarkable fuel savings. "GadCooler has fulfilled and even exceeded our expectations in providing cooling at low costs. We expect remarkable savings from the system installed," says Peter Lundberg, Chief Engineer at Finlandia. A GadCooler unit with a capacity of approximately 500 kW provides much of the cooling capacity needed onboard the vessel, operating between Helsinki and Tallinn with up to 2,000 passengers and 650 vehicles onboard.

In summertime cooling is typically a major onboard consumer of fuel. On big cruise ships operating in tropical conditions cooling can consume as much as some 10 MW of power. Normally cooling is provided by using cooling compressors. “GadCooler utilizes existing heat sources for providing cooling in a non-toxic absorption process, resembling the operational principles of gas refrigerators. Only a small amount of energy is needed for the transfer pumps resulting in fuel savings and also in less emissions,” notes Johan Aberg, Naval Architect at Gadlab Engineering. “We have developed the GadCooler to operate in a maritime environment. This requires specific design considerations to be incorporated. The result is an energy saving, efficient, quiet, and vibration free cooler with a short pay-back time for the owner,” summarizes Managing Director Markus Nuotio.

Gadlab Engineering provides the complete system including connection design with existing onboard systems. The GadCooler is fitted with a smart control system which optimizes the cooling efficiency. The GadCooler has received system approval by DNV GL. It is available as one or several units, each with a cooling power of up to 5,000 kW, still providing a practical system size for convenient installation.

Halton offers two new solutions for 'show galleys'

The popularity of TV cooking shows has inspired many people’s interest in cooking. Therefore, most of the major cruise lines are nowadays offering cooking demonstrations at sea – chefs preparing food and dishes in front of the passengers. Some of the cruise lines provide different types of culinary schools all the way from lectures to hand-on classes. The passengers' access to the ship's operational galley is not allowed and therefore the experience must be taken outside of the operational galley. Halton offers two interesting solutions for front cooking areas.

Halton JES is a high-efficiency jet extraction system that is designed for front cooking areas or architectural cooking concepts integrating appliances with medium input power like grills, woks and heating plates. Compared to traditional hoods, JES promotes the feeling of openness. Its design and the combination of glass/stainless steel make JES aesthetically pleasing and give the cooking area its unique style.

The performance of JES is impressive. The smoke test demonstrates the synergy of JES's three features; the proximity of glass plate to the smoke source naturally increases its capture efficiency, the aerodynamic nozzle determines the aspiration direction and the glass plate amplifies the cyclone efficiency thanks to the creation of a beneficial airstream along its surface, in the direction of the nozzle. Halton JES can be equipped with a fire suppression system and UV-light technology and thanks to its reduced dimensions and its modularity, JES can be customized to meet the customer's needs. Halton JES is in use on board several major cruise ships.

One of the Halton’s latest innovations is called Halton MobiChef. The system was launched for landside applications in 2014 and ever since that it has won several awards. The Marine version of the MobiChef will be available in summer 2016. The system unleashes cooking from any ventilation ductwork and is a completely autonomous mobile cooking station. In addition, the MobiChef combines Halton’s experience and knowledge in the field of ventilation with emission control for professional kitchens and galleys.

Halton’s MobiChef can be used with all electric cooking appliances, from light-duty table top equipment to traditional 700 and 900 mm deep modular equipment. E.g. fryers, grills and woks are easily managed by this innovative mobile cooking station. This is possible thanks to Halton Capture Jet technology which ensures the highest efficiency in capturing smoke and cooking odours and a highly efficient, fully integrated and compact recycling unit which makes MobiChef completely independent from any central ventilation system.

To prevent spillage of smoke, heat and impurities, Halton MobiChef cooking area is closed on the front and the sides are “locked” by Halton’s Capture Jet technology. Capture Jet creates an air curtain which captures efficiently smoke, heat and impurities released by the cooking appliances and steers them through the high efficiency filters into an integrated recycling unit.

The touch screen

Halton’s touch screen is based on the use of clear visuals that allow easy control of the main functions. The remaining lifetime
of the filters is clearly displayed so that maintenance operations can be easily planned.

Halton MobiChef controls ensure that one is always working with the correct airflow, no more, no less. The speed of the fan is adjusted automatically to compensate for filter pressure losses as the filter gets dirty. The exhaust airflow is then kept constant, ensuring that the capture efficiency remains at its maximum level whatever the state of the filters.

MobiChef advantages:
– Enables cooking outside of galleys
– The extensive use of glass
– The completely autonomous mobile cooking station with plug and play technology
– Utilizes Halton Capture JetTM technology to prevent heat and impurities produced by cooking appliances from spreading
– The integrated and compact recycling unit
– No need to be connected to the ship's ventilation system
– The intelligent touch screen with clear visuals to control main functions

Halton introduces completely new cabin ventilation system for cruise ships

HVAC consumes a substantial part of energy on board. Intelligent, modern ventilation system enables not only lower running costs but it improves safety and comfortable indoor climate conditions.

As a result of continuous research and development work, Halton Marine introduces a completely new cabin ventilation system for cruise ships at SMM 2016 exhibition held in Hamburg, Germany in September. The company believes that the new system will become an extremely interesting choice for cabin ventilation in the future as it offers enhanced cabin air comfort with the highest operational efficiency. In practice this can mean less investment and operational costs compared to more traditional systems like fancoils.

Halton will arrange a seminar on the new cabin ventilation system during SMM 2016. The participation requires pre-registration. For more information, contact Halton Marine (This email address is being protected from spambots. You need JavaScript enabled to view it.).

With nearly 20 years of experience in cabin ventilation, equipment and system deliveries for over 100,000 cabins on board, and full-scale indoor air laboratories in three continents, Halton’s expertise can offer real return on investment.
