MKN Steam Boiling Kettle 10018795 – Optima 850

Forty kilowatts of rated thermal load moving 180 litres of product through a 26-minute heat-up defines the output of this Optima 850 boiling kettle. Within a 1000 x 850 x 700 mm body it delivers a single work zone for large-volume production without going to a larger multi-kettle block.

On a ship, that 26-minute heat-up for a full 180-litre batch underpins menu planning and energy scheduling. A kettle that can reliably take bulk soups or sauces from fill to service temperature inside that time slot can be locked into a galley’s production rhythm, but it still occupies a 1000 x 850 mm footprint that must be justified in the layout. The 700 mm overall height and the 700 x 540 x 535 mm working surface keep loading and monitoring at a workable level from the deck, important where steps or platforms are not desirable in a moving galley. Net weight of 162 kg, rising to 195 kg gross, means that structural support and fixing detail have to be considered alongside adjacent Optima 850 appliances.

Technically, the kettle is configured as one work zone with a 700 x 540 x 535 mm working surface and a stated capacity of 180 litres. Steam pressure is specified between 0,5 and 0,8, and that band is what the ship’s steam supply or local generator has to provide if the quoted 40 kW thermal load and 26-minute heat-up are to be achieved consistently. The Optima 850 geometry at 1000 x 850 x 700 mm lets it sit in line with other modules on the same series, so trolleys and containers can run across the suite without steps or gaps between units.

The double-walled hinged lid on a swivel joint with condensate drip strip contributes directly to thermal performance and cleanability. Condensate is returned into the kettle instead of shedding onto the cover or deck, and the double wall reduces uncontrolled heat loss into the galley. A large drain valve with strainer is sized to empty the 180-litre body without manual dipping, separating product from waste and protecting downstream drains. Product temperature control ties the heat input to measured food temperature, rather than relying only on time. The integrated R3/4" tap with 250 mm reach brings make-up water directly over the working surface, cutting hose runs and manual handling at the fill stage.

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 a good fit where a galley needs a single, central 180-litre boiling station with a 40 kW thermal load and a verified 26-minute heat-up time, integrated into an Optima 850 run. It is the wrong choice for very small galleys that cannot keep a 180-litre batch turning over, or for layouts where a 1000 x 850 mm footprint cannot be allocated to a dedicated boiling kettle.
