MKN Steam Boiling Kettle 10018568 – Optima 850

Forty‑one kilowatts of rated thermal load driving a 150‑litre vessel to temperature in 24 minutes sets the performance level for the MKN 10018568 steam boiling kettle. The round kettle body offers a working surface of Ø 665 x 500 mm, so this is a high‑volume unit within the Optima 850 line rather than a small auxiliary pan.

At 1000 x 850 x 700 mm, the kettle footprint is compatible with Optima 850 cooking blocks where depth continuity and flush lines matter for galley planning. Net weight is 155 kg, rising to 188 kg gross for logistics and handling calculations; those numbers sit on the foundation and deck-loading checks that come before any marine installation. Steam pressure is specified in the 0,5 – 0,8 range, so the jacket supply and controls have to be matched to that band when the steam plant is designed or tied into an existing system.

The round stainless steel vessel with radiused base edges and fully welded construction is aimed squarely at shipboard cleaning practice. Radiused edges mean there is no sharp internal corner to trap product when the kettle is drained, which helps both hygiene and turn‑round time between batches. The double‑walled hinged lid with swivel joint and condensate drip strip manages condensate back into the vessel rather than onto the worktop, which matters on a moving deck where any standing liquid on adjacent surfaces quickly becomes a slip hazard. With a single work zone and product temperature control, the kettle is set up for straightforward boiling and simmering duty rather than multi‑zone cooking.

Heat‑up time of 24 min for the 150‑litre capacity defines how the kettle fits into a production sequence. On a vessel running repeated batches through one pan, that figure is a planning parameter: it determines how early the kettle must be brought online before service and how many full cycles are realistic in a shift without overloading the steam plant. The 0,5 – 0,8 steam pressure band again ties the unit to a stable jacket steam supply; underspecifying that side shows up immediately in extended heat‑up times.

Build and control

• Stainless steel 1.4301 (AISI 304) throughout
• Self-supporting closed construction
• Round stainless steel vessel with radiused base edges, fully welded
• 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 with 250 mm reach

This kettle is the right choice where a single, relatively compact 150‑litre boiling position is required in an Optima 850 cooking line and the vessel supply can deliver the 41 kW thermal load and the 0,5 – 0,8 steam pressure band. It is the wrong choice where multiple smaller kettles would give more flexibility in menu planning, or where there is no suitable steam infrastructure and direct‑heated equipment is preferred.
