MKN Steam Boiling Kettle 10018794 – Optima 850

Thirty-two kilowatts of rated thermal load driving a 130-litre vessel in 23 minutes sets the MKN 10018794 steam boiling kettle apart in the Optima 850 line. The body footprint of 800 x 850 x 700 mm keeps that capacity compact enough for a main galley block where deck area is tightly planned.

On a ship, that pairing of 130 litres and a 23 min heat-up time matters directly to service planning. A kettle that comes up slowly forces earlier firing and longer burner-on hours, adding to fuel use and heat rejection into the galley. Here, the quoted heat-up figure and the 32 kW thermal load give the designer a concrete basis to size electrical or steam generation and to coordinate batch cooking around watch changes or buffet peaks. The 138 kg net weight also goes into the structural calculation, especially where kettles are grouped on a shared plinth.

The Optima 850 geometry shows in the 800 x 850 x 700 mm external dimensions and in the working surface of 500 x 540 x 535 mm. That working surface defines how much actual cooking space is available for product, and the 130-litre capacity tells you how deep to load it. Steam pressure is specified between 0,5 and 0,8, so the jacket and controls are sized for a defined operating window rather than an unspecified steam supply. Net weight is 138 kg with a gross shipping weight of 151 kg, which informs how the unit is moved through the yard and lifted into place. With a single work zone, there is no internal subdivision to manage; the whole kettle volume is one controlled cooking chamber.

The lid and draining details are part of day-to-day operation. The double-walled hinged lid with swivel joint and condensate drip strip keeps condensate where it belongs instead of on the deck or front face. A large drain valve with strainer allows product to be drawn off without passing solids into the drain, which is essential when the kettle is used for stocks or sauces that will be finished elsewhere. The specified R3/4" tap with 250 mm reach brings make-up water directly to the working surface, so staff do not carry water across the galley to charge or top up the vessel.

Build and control

• Stainless steel 1.4301 (AISI 304) throughout
• Self-supporting closed construction
• 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, 250 mm reach

This kettle is sized for galleys that need a single 130-litre body as part of an Optima 850 line-up, with steam pressure between 0,5 and 0,8 available and room for an 800 x 850 mm module. It is not the right choice where multiple smaller batches are required across different products at once, because the single work zone ties the whole 130-litre capacity to one temperature profile.
