Electrolux Professional Undercounter Dishwasher 502744 – Undercounter, atmospheric boiler, double skin, drain pump, det&rinse aid disp,USPH,540d/h-50Hz-Mar

Thirty baskets per hour at 18 dishes per basket sets the 502744 at 540 dishes/hour in a compact undercounter footprint. With external dimensions of 600 x 615 x 820 mm, it slots under a standard counter while still taking 500 x 500 mm baskets in a 335 mm-high wash cell.

On board, that combination of throughput and size matters in smaller sculleries and officer messes where a hood-type machine would dominate the deck. The 400 V/3 ph/50 Hz supply aligns with vessels built around a 400 V distribution rather than a 440 V marine grid, which makes it suitable for ships that already carry 400 V galley equipment or for shore-based catering in shipyards and offshore facilities operating on 50 Hz. A quoted noise level of 61 dBA keeps sound pressure manageable in open galleys where the machine runs through service.

Installed power is 6.85 kW, with 6 kW dedicated to the atmospheric boiler and 2 kW to the tank heating elements. The boiler holds 12 litres, the wash tank 23 litres, and the machine is designed for a 50 °C inlet water supply. That upstream preheat means the boiler can bring rinse water to a controlled 80–90 °C band without relying on an oversized element. Three programme cycle times — 120, 180 and 240 seconds — let the operator balance throughput against soil level and contact time within the 30 baskets/hour rating.

The cell takes 500 x 500 mm racks, so standard glass, plate and cutlery baskets fit without adapters. Water consumption per cycle is listed at 0 / 2.5 litres, which reflects the fresh-water draw for the rinse; in a context where fresh water is bunkered or generated, that figure feeds straight into daily water production and waste tank calculations. The inlet water supply pressure is specified between 0.5 and 7 bar (7–102 psi), matching a wide range of shipboard hydrophore and booster configurations without additional pressure regulation, and the drain line size is 20.5 mm, which should be allowed for in the scupper or drain manifold design.

Build and control

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

Double-skin construction improves thermal and acoustic insulation, which reduces both heat rejection into a small galley and operator exposure to pump noise. The built-in drain pump helps where the deck drain is higher than the machine’s base or where long horizontal drain runs are unavoidable. HACCP data logging and Wash Safe Control rinse temperature monitoring give a record of 68 °C wash temperature and 80–90 °C rinse performance, which is increasingly a requirement on inspected vessels rather than a convenience.

This machine is a good fit where 30 baskets/hour is a genuine upper bound — small galleys, officer messes, or galleys that spread washing across the watch. It is not the right choice for a main scullery on a large passenger vessel, where a hood-type or rack conveyor rated for higher basket counts is typically needed.
