Electrolux Professional Undercounter Dishwasher 502713 – Undercounter, pressure boiler, double skin, drain pump, det&rinse aid dispensers,720d/h-60Hz

Forty baskets and 720 dishes per hour at a fixed 90/120/240 second cycle choice set the workload for the 502713 undercounter dishwasher. With a 500 x 500 x 335 mm wash cell, it takes standard marine racks without wasted volume.

On a ship this matters because wash-up normally shares space with preparation and servery, not a separate scullery. At 600 x 615 x 820 mm, this machine fits under a standard counter run, so it can sit close to the points where racks are generated. The 61 dBA quoted noise level means it can operate in the same space as service without dominating it.

The unit runs on a 440 V/3 ph/60 Hz supply with 6.85 kW default installed power, so it drops directly onto a shipboard 60 Hz distribution rather than a shore-only specification. Of that load, 6 kW is boiler heating and 2 kW is tank heating, with a 0.736 kW wash pump driving circulation. The boiler holds 12 litres and the wash tank 23 litres, and at the specified 50 °C inlet water supply the pressure boiler lifts rinse temperatures into the 80–90 °C band. Wash temperature is held between 55 and 65 °C, which is the key number for soil removal and hygiene, not just comfort for the operator.

Rinse water consumption is quoted as 0 / 2.5 litres per cycle, with the 2.5 litres being the operating figure once connected. At the published 40 baskets per hour that equates to a predictable draw on the vessel’s fresh-water plant. The inlet water supply pressure range of 2–3 bar (29–44 psi) and the matching 2–3 bar line marked as minimum/maximum means the machine is intended for a stabilised ship system, not a domestic feed that may swing outside those limits. The drain line size is 20.5 mm, so the ship’s scupper and grey-water connection can be planned from the spec sheet without field improvisation. Cell dimensions of 500 mm width and depth match the basket size, and the 335 mm height leaves clearance for typical glassware and plates.

Packaging dimensions at 690 x 620 x 920 mm are logistics numbers rather than installation ones, but they do tell you whether the crated unit will pass through existing hatches and corridors without uncrating on the quay.

Build and control

• IPX4 rated against water ingress
• HACCP data logging
• Digital control display
• Automatic wash cycle
• Built-in drain pump
• Detergent and rinse-aid dispensers
• Double-skin insulated construction

This machine suits small to medium galleys that generate a steady but not excessive flow of racks, such as crew messes or speciality outlets, where undercounter equipment is easier to integrate than a hood-type or rack conveyor line. It is not the right choice where 40 baskets per hour is clearly below the peak demand, or where the warewashing station already has space and power reserved for a larger machine.
