MKN Bain-Marie 2020505 – Optima 850

A 305 x 510 x 200 mm working surface on a 400 x 850 x 700 mm body defines this Optima 850 bain-marie as a compact, single-well holder rather than a large service island. With 1.5 kW electrical power at 230 V, it is specified to keep pre-heated containers in temperature rather than to act as a primary cooking source.

On board, that distinction matters for both electrical and space planning. A bain-marie in a main galley or pantry is often tied into a service line; here the 400 mm length and 850 mm depth allow it to drop into an Optima 850 run without disturbing the line geometry. At 700 mm height it stays aligned with the rest of the series, so GN containers can be moved along the line without step changes. The 1.5 kW load at 230 V is light enough to sit on a small local sub-distribution board, which is often how snack points or secondary counters are supplied on a vessel.

The working surface of 305 x 510 x 200 mm gives a clearly defined capacity envelope. Galley designers can plan the bain-marie around a known well size, rather than guessing from external dimensions. The surrounding chrome-nickel steel 1.4301 / AISI 304 construction is standard catering-grade stainless and matches other Optima 850 modules, so the visual and hygienic finish is consistent when this unit is placed between ranges, fryers or neutral tops in the same line. Net weight is 37 kg with a quoted gross weight of 44 kg, so handling at installation is manageable without special lifting arrangements, yet the unit still has enough mass to sit securely once fixed to its support structure.

Operating from a 230 V supply means the bain-marie can be allocated to a dedicated circuit without competing with heavy three-phase cooking appliances. In refit situations where existing cabling is limited, that can be the deciding factor between adding hot holding to a counter or leaving it cold. The 1.5 kW figure also becomes part of the HVAC calculation: it represents a modest continuous heat source compared with main galley cooking equipment, but in a small pantry its contribution to room load should still be counted.

Build and control

• Chrome-nickel steel 1.4301 / AISI 304 construction
• Optima 850 series geometry with 400 x 850 x 700 mm external dimensions
• 305 x 510 x 200 mm working surface sized as a single well
• Electric operation at 230 V
• 1.5 kW electrical power for hot holding duty
• Net weight 37 kg, gross weight 44 kg for installation planning

This unit is a good fit where a single GN-sized well is needed in an Optima 850 line or a compact service counter, and where only a 230 V connection is available. It is not the right choice for a main production galley that needs multiple wells or higher installed power for bulk regeneration; those applications call for larger bodies within the same modular family.
