MKN Steam Boiling Kettle 10029365 – Optima 850

Five hundred litres in a single vessel sets this Optima 850 boiling kettle apart from smaller galley kettles. With a rated thermal load of 63 kW and a quoted heat-up time of 52 min, it is built for high-volume cooking where a full batch really uses that capacity.

On a ship, that combination of 500 litres and 63 kW has to be planned into both the galley layout and the ship’s utilities. The 2000 x 850 x 700 mm body sits in the Optima 850 line, so it aligns with the rest of the 850 mm-deep cooking suite and keeps a continuous working edge for large pots and trays. Net weight is 305 kg and gross shipping weight 335 kg, figures the yard will want when checking deck loading and handling during installation. Steam pressure for the integrated heating system runs in the 0,5 - 0,8 range, so the kettle’s performance is defined and repeatable once set up on board.

The working surface on this model measures 1690 x 665 x 465 mm, giving a generous loading and handling area around the pan while staying within the Optima 850 footprint. One work zone keeps operation straightforward when large single batches are the norm. Product temperature control is part of the standard specification, so the operator can work to a defined setpoint instead of watching for boil behaviour in a pan of this size. When the cooking phase is finished, the large drain valve with strainer is what moves 500 litres of product or cooking liquid out in a controlled way rather than relying on manual transfer.

Heat-up performance is directly tied to the published numbers: 63 kW into 500 litres with a 52 min heat-up time. For a galley planning several turns per service, that defines how early the kettle has to be brought online. Steam pressure between 0,5 and 0,8 gives enough adjustment to match different cooking tasks while staying within the kettle’s design envelope. The R3/4" tap with 250 mm reach removes the need to bring separate water hoses into the area, simplifying filling and cleaning routines at the kettle.

Build and control

• Stainless steel 1.4301 (AISI 304) throughout
• Self-supporting closed construction
• Ergonomic knob control
• Large drain valve with strainer
• Double-walled hinged lid with swivel joint and condensate drip strip
• Product temperature control
• R3/4" tap, 250 mm reach

This unit fits a main galley or cook-chill production area where 500-litre batches are realistic and service patterns justify a single large vessel. It is not the right choice for a small crew galley or a vessel with highly variable, small-batch menus, where a smaller kettle or multiple smaller pans would be easier to schedule and occupy less of the galley’s connected load.
