Electrolux Professional Free-Cooking Top 589891 – thermaline 90, 1000 mm Electric Free-cooking Top with Smooth Plate, 1 Side

16 kW on a 1000 x 900 mm plate is the defining figure for the thermaline 90 free-cooking top 589891. The smooth surface runs from 80 °C up to 350 °C, so it can cover gentle holding and high-temperature finishing on the same footprint.

On a shipboard galley the 440 V/3 ph/50/60 Hz supply aligns with standard marine switchboards, which simplifies both newbuild specification and retrofits. At 250 mm body height this top fits the thermaline 90 modular system, so it can sit over bases or blocks built to the same depth. The 160 kg net weight is part of the structural calculation for flanged feet or a welded plinth, and it is also a consideration for installation on upper decks where point loads are checked by the yard.

The working band from 80 °C to 350 °C allows this free-cooking surface to pick up low-temperature items without scorching and then step straight into searing. Temperature is delivered across the full 1000 mm width, which lets a galley run multiple zones in practice even though the surface itself is smooth. The 40 A current consumption needs to be allowed for in the panelboard design alongside other thermaline 90 modules drawing from the same section. Being one-side operated, the 589891 is intended for a traditional line rather than a pass-through island.

Construction in AISI 304 (1.4301) stainless steel with a stainless steel internal frame gives this unit the stiffness needed for heavy daily use in a seagoing environment. Wetted parts in AISI 316L stainless steel are specified where contact with water is expected, which matters aboard where chlorides from saltwater and air can shorten the life of lesser alloys. Built to DIN 18860-2 with a drop-nose worktop, the module mates cleanly with adjacent thermaline 90 units using the THERMODUL jointing system, so soil and liquids do not collect in open seams between appliances.

Build and control

• IPX5 rated against water ingress
• AISI 304 (1.4301) stainless steel construction
• AISI 316L stainless steel in wetted parts
• Built to DIN 18860-2 with drop-nose worktop
• THERMODUL jointing for a seamless run of units
• Stainless steel internal frame
• Digital control display
• Overheat cut-out
• Standby mode for reduced idle consumption
• Front access to components for service
• Metal knobs with hygienic soft-touch grips

IPX5 protection lets the unit stand up to hose-down cleaning regimes common in marine galleys, within the limits of that rating. Digital control with metal knobs gives clear temperature setting while still being operable with wet or gloved hands, and the overheat cut-out protects both the plate and the ship’s electrical system from misuse. Standby mode reduces idle consumption, which is relevant on vessels where generator loading and fuel burn are watched closely.

This is the right choice where a galley needs a high-output, smooth free-cooking surface integrated into a thermaline 90 run, fed from a 440 V/3 ph/50/60 Hz supply. It is not the right unit where the requirement is for two-side service on an island or where a textured grilling surface is mandatory; those layouts call for different tops in the same family.
