Electrolux Professional Hood Type Dishwasher 505080 – green&clean, hood type Dishwasher

Nine point nine kilowatts on a 440 V/3 ph/60 Hz supply sets the 505080 firmly in the marine hood-type class. With a 24 litre wash tank and a 12 litre boiler, it is sized for continuous service in a galley that needs compact, stand-alone warewashing rather than a full rack conveyor line.

Running at shipboard 440 V/3 ph/60 Hz avoids the transformer and frequency issues that come with adapting a shore-spec machine, and it matters because both the 3 kW tank heating elements and the 9 kW boiler elements are working continuously during peak wash-up. Inlet water supply pressure is specified from 0.5 to 7 bar, a wide enough band to cope with pressure fluctuations on a vessel’s ring main. The machine also has to be tied into the galley HVAC calculation: it releases 2,000 W of sensible and 500 W of latent heat into the room when operating, which will show up directly on the air-conditioning load profile.

The boiler and tank volumes drive how the dishwasher behaves over a service. A 24 litre tank gives a stable wash bath, and the separate 12 litre boiler feeding 84 °C rinse water maintains final sanitizing temperature. The wash temperature under NSF/ANSI 3 compliant operation is 75 °C. Water supply temperature can range from 10 to 65 °C, which means the unit can work with relatively cold feed from the vessel’s potable water system without external preheat. Water consumption per cycle is listed as 0 / 2 litres, corresponding to the selectable operating modes published for this model family, and is where freshwater planning starts for a ship making its own water. Three cycles are available, matching different soil loads and turnaround needs.

Physically, the 505080 sits at 746 mm wide, 755 mm deep and 1549 mm high. That footprint fits a standard single-person wash-up corner and leaves space for inlet and outlet tables in most galley layouts, but it still needs the deckhead height and hood opening clearance checked at design stage. Net weight is 106 kg, rising to a 126 kg shipping weight with a packed volume of 1.23 m³, figures the yard will use when planning intake routes and any lifting required.

Noise level is quoted below 68 dBA, a figure that matters in an enclosed marine galley where dishwashing runs alongside preparation. The drain line size is 20.5 mm, so the scupper or waste connection in the pot-wash area must be detailed to suit rather than assumed.

Build and control

• IPX5 rated against water ingress
• HACCP data logging
• Automatic wash cycle
• Detergent and rinse-aid dispensers

This hood-type machine is the right choice where wash-up is batch-based around service peaks and deck area will not justify a rack conveyor. It is less suitable where the vessel’s profile or service concept demands a continuous high-volume flow of racks; in that case, a rack-type machine from the same green&clean series is the better fit.
