Electrolux Professional Hood Type Dishwasher 505079 – green&clean, hood type Dishwasher

9.9 kW of installed electric load on a 400 V/3 ph/50 Hz supply sets the Electrolux Professional 505079 apart from lighter hood machines. With a 24 litre wash tank and a 12 litre boiler, it is sized for continuous work in a ship’s main galley rather than occasional back-up duty.

On board, warewashing is often constrained by both electrical capacity and fresh water. This hood type runs on a standard 400 V/3 ph/50 Hz line, which aligns with many marine hotel-service distributions specified out of European yards. Water use per cycle is quoted as 0/2 litres, so the higher figure can feed straight into the vessel’s water-making and waste-handling calculations. In a space where deck area and HVAC capacity are budgeted as tightly as kW and litres per hour, those numbers are not abstract — they dictate how many hoods can run in parallel and how close this machine can sit to other heat sources.

The tank heating elements are rated at 3 kW, maintaining wash liquor in the tank, while the boiler heating elements carry 9 kW to guarantee rinse performance at the specified 84 °C rinse temperature. The NSF/ANSI 3 compliant wash temperature is set at 75 °C, so thermal disinfection is built into the cycle rather than left to chemical dosing alone. Three programmed cycles are available, giving the galley flexibility between throughput and contact time within the same footprint. The machine accepts inlet water at 10–65 °C and an inlet pressure from 0.5 to 7 bar, which covers the typical range on a ship where pressure can vary with tank level and pump configuration.

With external dimensions of 746 mm width, 755 mm depth and 1549 mm height, the 505079 is compact enough to sit in a straight-run scullery without obstructing passageways, yet tall enough under the hood to take standard racks and typical potware. Net weight is 106 kg, rising to 125 kg in shipping configuration over a 1.23 m³ volume, so the structural load on the deck and the space needed for getting the crate through companionways can be calculated in advance. Heat rejection into the room is quoted as 2,000 W sensible and 500 W latent, figures that belong in the HVAC schedule because they add directly to the galley’s cooling load. Noise is kept below 68 dBA, which matters in open galley layouts where warewashing sits close to prep and plating.

Build and control

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

This unit is the right choice where the galley needs a dedicated hood machine working throughout service: three cycles, a 24 litre tank and a 12 litre boiler match that pattern. It is less suitable for very small pantries or galleys that only wash intermittently between short meal periods, where the electrical load and HVAC impact of a 9.9 kW hood could be disproportionate to use.
