MKN Electric Boiling Kettle 10018799 – Optima 850

One hundred eighty litres of kettle volume, a 25.8 kW electrical load and a quoted 41 min heat-up time define the MKN 10018799 module in the Optima 850 series. Those figures put a full production kettle into a 1000 x 850 x 700 mm body, which means a single section in an 850-deep cooking block carries a full batch station.

On board, that combination of capacity and power has to be read directly against the ship’s electrical and space planning. At 25.8 kW on 400 V, this is a main-galley appliance that belongs on a dedicated circuit and in the load calculation, not an item added late to a service galley board. The 41 min heat-up time is a scheduling tool: it tells the galley when to start heating a 180-litre batch so that stocks or sauces are ready at the right point in the watch without unnecessarily long holding that would add heat and moisture to an already enclosed space.

The 1000 x 850 x 700 mm external dimensions align with the Optima 850 depth so the kettle can be installed flush with neighbouring modules in the same series. The specified working surface of 700 x 540 x 535 mm describes the usable kettle area within that footprint and helps the designer understand how much deck in front of the unit must be kept clear for stirring, tilting and draining. Net weight of 178 kg and a gross shipping weight of 211 kg tell the yard what the foundation and coaming have to support when this unit is bolted in alongside other heavy cooking appliances.

Heating is via the VAPRO system with a separate steam generator, not direct immersion elements in the kettle space. Cylindrical stainless steel elements heat the generator water, and energy is passed into the 180-litre volume through the jacket under intelligent heating control. That control, together with preparation for connection to an energy optimisation system, lets the ship’s power management sequence the 25.8 kW draw with other large galley consumers so that the published 41 min heat-up remains realistic in normal operation.

Build and control

• Stainless steel 1.4301 (AISI 304) throughout
• Self-supporting closed construction
• Can be connected to the mains water supply
• Ergonomic knob control
• Energy-efficient VAPRO heating system with separate steam generator
• Generator heated by cylindrical stainless steel elements
• Intelligent heating control
• Prepared for connection to an energy optimisation system
• Large drain valve with strainer
• Double-walled hinged lid with swivel joint and condensate drip strip

The double-walled hinged lid with swivel joint and condensate drip strip is there to keep heat and condensate inside the kettle rather than on the deck and surrounding equipment, which matters at 180 litres. The large drain valve with strainer supports quick, controlled emptying of full batches while catching solids before they reach the ship’s waste system, helping to protect galley drainage runs. Connection to the mains water supply simplifies filling and makes it easier to repeat the same batch volume on every cycle.

This model suits main galleys and larger crew kitchens that can genuinely use 180-litre batches and have allowance in the switchboard design for a 25.8 kW, 400 V appliance. It is the wrong choice where production is built around much smaller pans, limited electrical capacity, or where a more flexible multifunctional unit is expected to cover frying, pressure cooking and shallow work as well as boiling.
