Electrolux Professional Neutral Base Unit 589898 – thermaline 90, Sink unit on closed base, 1 Side

Four hundred millimetres of deck width for a full sink module is what defines the thermaline 90 unit 589898. At 900 mm deep and 700 mm high, it ties into the rest of the line as a one-side operated sink on a closed base, not as an afterthought bowl dropped into a counter.

On a ship, those 400 mm are usually the margin between having a hand-wash or utility sink at the cooking line and losing worktop to a larger module. This unit keeps the footprint tight while still bringing a 3/4" incoming cold/hot water line and a 1" drain into the block. Because it sits at the same 900 mm depth as the rest of thermaline 90, it aligns with adjacent cooking modules and can be joined in a single hygienic run.

External dimensions are 400 mm in width, 900 mm in depth and 700 mm in height, with a net weight of 38 kg. That weight is low enough for straightforward handling during installation but substantial enough that, once fixed to a plinth or deck, the sink becomes part of the galley structure. The 3/4" inlet water line size and matching 3/4" incoming cold/hot water line simplify tie-in to the ship’s service manifold, while the 1" drain line size gives the fall and capacity needed to clear the bowl without backing up into the work area.

Being part of thermaline 90 means the sink unit shares the same construction logic as the cooking modules. The top is built to DIN 18860-2 with a drop-nose worktop profile, so edges are defined and clearable and junctions to adjacent units are predictable for the yard. The 900 mm depth also means this neutral module can sit in the middle of a thermaline 90 line without creating a step or recess that traps soil or complicates cleaning.

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

This is the right choice where the requirement is a compact, fully integrated sink on a closed base as part of a thermaline 90 island or wall line, and where IPX5 washdown and a defined 3/4"/1" connection set match the ship’s services. It is not the right unit if the project calls for an open GN-conform storage base or for a wider preparation sink body; in those cases, larger neutral bases in the same series should be considered.
