Electrolux Professional Neutral Base Unit 589909 – thermaline 90, 300 mm Closed base, 1 Side - H=450

Three hundred millimetres of width and a height of 450 mm define the footprint of the thermaline 90 neutral base unit 589909. At 900 mm depth it matches the cooking modules in the same line, closing off one side and carrying only 9.5 kg of its own weight.

On a ship this format matters where every cooking top needs a structurally sound, hygienic support without adding unnecessary mass. A 300 mm element can fill a residual gap in a block or carry storage beneath a niche appliance while staying within the galley’s planned service corridor width. The 450 mm body height allows the designer to align this base with other thermaline 90 components on plinths or feet so deck cleaning access and USPH-style hygiene detailing can be handled consistently along the run.

The neutral base has no gas or electric function of its own, but it has to take the load and heat bleed of the module above it. Built in AISI 304 (1.4301) stainless steel, it uses a stainless steel internal frame to transfer that load into the deck or plinth beneath. At 900 mm depth the carcass ties into the thermaline 90 geometry, so tops, boiling pans, fryers or other modules sit flush without steps or overhangs that would trap soil. The 300 mm width gives just enough body to support an edge module or infill without turning into unused volume that has to be cleaned around for the life of the vessel.

DIN 18860-2 construction with a drop-nose worktop profile gives the unit a clearly defined edge and a consistent overhang against the recessed plinth zone. That geometry is what lets the cleaning regime work: high-pressure spray can reach the recessed base, while the drop nose stops water and debris from migrating into joints. Net weight of 9.5 kg keeps manual handling manageable during installation or refit without compromising the rigidity of the frame.

Build and control

• IPX5 rated against water ingress
• AISI 304 (1.4301) stainless steel construction
• Built to DIN 18860-2 with drop-nose worktop
• THERMODUL jointing for a seamless run of units
• Stainless steel internal frame
• Front access to components for service

THERMODUL jointing is the interface that lets this 300 mm closed base sit between active modules as part of a continuous line. It closes gaps that would otherwise collect food soil while still allowing a single piece to be removed later without disturbing the rest of the block. Front access to components means that if the base carries services or fixings for the top unit, those can be reached from the working side without pulling the block away from its deck fixings.

This is the right choice where a one-side-operated thermaline 90 line needs a narrow closed section to complete a 900 mm deep run, for example between two larger modules or at the end of a cantilevered block. It is the wrong part where the design brief calls for open GN storage or a wider cupboard, because 300 mm of closed base offers structure, not volume.
