MKN Electric Boiling Kettle 2122802C – Optima 700

Sixty litres of boiling capacity in an 800 x 700 mm footprint is the defining trade-off on the MKN 2122802C. The round vessel with a Ø 500 x 378 mm working surface is built into a 800 x 700 x 700 mm body, so it occupies a compact cube of space while still delivering a full 60 litres.

On board, that 800 x 700 x 700 mm envelope makes the kettle a planning piece for smaller production galleys and catering spaces where deck area and circulation lanes are tight. The published 100 kg net weight and 109 kg gross weight are modest for a fixed boiling kettle, but still need to be checked against the deck load plan and any stainless plinth or coaming the shipyard provides. The 60-litre capacity suits batch cooking for a defined complement on a short provisioning cycle; it is not intended as the main bulk-preparation kettle where food production runs continuously across long intervals between stores.

The 16 kW electrical power draw at 400 V is the key figure for the electrical design. At full load the kettle represents a significant consumer on a galley sub-board, so grouping it with other heavy appliances on the same feeder and breaker needs to be considered early in the layout. The 21 min heat-up time quoted for the 60 litres is the operating reference point: it lets the galley plan back from service, knowing how far in advance to start a batch from cold. The VAPRO heating system with separate steam generator sits between the cylindrical stainless steel elements and the pan, so the vessel is heated indirectly by jacket steam under intelligent heating control.

The inner vessel is a round stainless steel shell with radiused base edges and a fully welded construction, which reduces product residues at seams and corners and simplifies manual cleaning after starchy or protein-rich cooks. Stainless steel 1.4301 (AISI 304) is used throughout the body, a standard kitchen grade for galley environments when cleaning and rinsing regimes are properly maintained. One work zone is provided, so the entire 60 litres run at a single temperature setpoint; this is a straightforward boiling kettle rather than a multi-zone or multifunction appliance.

Build and control

• Stainless steel 1.4301 (AISI 304) throughout
• Self-supporting closed construction
• Round stainless steel vessel with radiused base edges, fully welded
• 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

The large drain valve with integrated strainer shapes daily operation, allowing liquid product to be drawn off cleanly while retaining solids, or for the vessel to be emptied rapidly between batches. Connection to the mains water supply simplifies filling and cleaning; on a ship where potable water is produced and metered, that connection should be positioned so that it is accessible for maintenance and isolation.

This kettle is the right choice where a galley needs a 60-litre electric boiling function in the Optima 700 line and has 16 kW available on a 400 V circuit. It is the wrong choice where production volumes demand much larger boiling batches or where the available electrical power on the galley board cannot support a 16 kW appliance.
