MKN Electric Boiling Kettle 10018553 – Optima 850

One hundred litres in a single round vessel defines this Optima 850 boiling kettle, MKN article 10018553. With 21 kW of electrical power and a quoted heat-up time of 26 min, it is sized for batch production rather than small-batch mise en place.

On a shipboard galley line, the 800 x 850 x 700 mm body fits the Optima 850 depth so pans and kettles can run in a straight, flush worktop. That simplifies layout and keeps service corridors clear, which matters more at sea than in most shore kitchens. At 125 kg net weight, this is a fixed installation that will be bolted or welded down and treated as part of the galley structure, so reserving deck space and planning drainage and power routes early in the build is essential.

The working surface is a Ø 630 x 397 mm round stainless steel vessel with radiused base edges, fully welded. That geometry gives the 100 litre capacity without sharp corners, so product movement and cleaning both stay predictable. The vessel can be connected to the mains water supply, which turns filling into a closed-hose operation instead of handling buckets or separate hose reels around a hot surface. Heat is delivered by the VAPRO system: an energy-efficient separate steam generator heated by cylindrical stainless steel elements. Because the kettle is heated indirectly by jacket steam, the vessel wall temperature is controlled by the generator rather than by direct immersion elements, and surface temperature stays even.

Electrical power is 21 kW at 400 V, controlled by an intelligent heating control that regulates the VAPRO generator. The published 26 min heat-up time is the practical figure to use in production planning and in sizing the electrical distribution — this is the load the switchboard sees during start-up. The kettle is prepared for connection to an energy optimisation system, so the ship’s overall power management can prioritise or shed load instead of relying on manual coordination between galley and engine control room.

Build and control

• Stainless steel 1.4301 (AISI 304) throughout
• Self-supporting closed construction
• Round stainless steel vessel with radiused base edges, fully welded
• 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
• Can be connected to the mains water supply
• Large drain valve with strainer
• Double-walled hinged lid with swivel joint and condensate drip strip

The large drain valve with strainer is a daily-use component: it lets product or cooking water leave the vessel under control while catching solids, which is as much about protecting the ship’s drain system as about food safety. The double-walled hinged lid on a swivel joint, with its condensate drip strip, keeps steam and condensate within the footprint of the kettle rather than on surrounding surfaces, which reduces both heat load and cleaning around the unit.

This 100 litre body is a good fit where there is a recurring need for single-product batches at that scale; it is the wrong choice for a galley that rarely needs more than small, highly varied runs, where a smaller kettle or a multifunctional pan may make better use of electrical and deck capacity. Ordered under MKN product number 10018553 in the Optima 850 series.
