MKN Steam Boiling Kettle 10019199 – Optima 850

Sixty litres of usable volume with a 23 kW rated thermal load gives this Optima 850 steam boiling kettle a quoted heat-up time of 17 min. The round vessel at Ø 500 x 378 mm is fully welded with radiused base edges, so the working surface is compact against its 1100 x 850 x 700 mm body.

On board, those figures translate directly into how the galley plans its production and its utilities. A 60-litre kettle suits smaller batch cooking, side production in a larger galley, or a diet kitchen that needs independent capacity without dedicating a large footprint. At 1100 x 850 mm it sits cleanly in an Optima 850 line without pushing the run too far into the deck, and at 700 mm height it stays under typical serving counter lines and servery hatches. Net weight is 174 kg, rising to 209 kg gross for transport and installation calculations, which matters for deck loading and handling into the space.

The vessel is round stainless steel with a radiused base and fully welded construction, so there are no internal seams to collect soil. That is important in a marine galley where cleaning has to happen quickly between services and in confined spaces. Steam pressure is specified between 0,5 and 0,8, matched to the 23 kW heat input, giving a controlled boil rather than a hard, aggressive rolling action. With product temperature control built in, the kettle can be held at setpoints rather than run open-ended at full power, which reduces supervision and helps avoid product scorching on the jacket wall.

Mechanically, the kettle vessel is pivot-mounted left and right within the frame, with a far-forward pivot point for controlled pouring. That geometry matters when the deck is moving; it allows the operator to bring the spout clear over GN containers or pans without dragging the whole frame forward. A large drain valve with strainer provides an alternative emptying route for thinner products, and the strainer protects the drain from blockages during service. The double-walled hinged lid sits on a swivel joint and carries a condensate drip strip, keeping condensation running back into the pan instead of over the front edge.

The self-supporting closed construction in stainless steel 1.4301 (AISI 304) throughout gives the frame the rigidity it needs to carry a 60-litre pivoting vessel. An ergonomic knob control layout keeps operation simple, which is relevant where crews rotate and language skills vary. The standard R3/4" tap with 250 mm reach brings water directly to the vessel, so there is no need to swing separate hoses across a hot line to fill the kettle for each batch.

This 60-litre body is the right choice where the galley needs boiling and simmering capacity without committing to larger, heavier kettles, or where the Optima 850 line has limited depth to spare. It is not the best fit for a main production kitchen cooking very large volumes in single batches, which should be looking at bigger bodies in the same range.
