MKN Steam Boiling Kettle 10019204 – Electric, Optima 850

Forty‑one kilowatts of rated thermal load driving 150 litres in a round vessel sets this Optima 850 kettle apart in the line. With a quoted heat‑up time of 24 min and a working surface of Ø 665 x 500 mm, it is sized for main production on a medium galley deck rather than as a small side kettle.

On board, that 1300 x 850 x 700 mm footprint has to sit cleanly in an Optima 850 cooking block and still respect deck clearance and cleaning access around the equipment. The Optima 850 body depth of 850 mm allows this kettle to line up flush with adjacent modules so pans and trolleys move across without lips or steps, which matters in a moving galley. Net weight is 220 kg (255 kg gross), so the ship’s structure and foundations need to be specified to take that static load plus product, not treated as a light counter‑top appliance.

The kettle vessel itself is round stainless steel with radiused base edges and is fully welded, which gives a continuous cooking and cleaning surface from wall to base without seams. Capacity is 150 litres, matched to the Ø 665 x 500 mm working surface so volume is usable rather than theoretical. Steam pressure for operation is specified between 0,5 and 0,8, so the jacket and controls are set up around a defined pressure band; that range is what underpins the 24 min heat‑up time to working temperature. For liquid and semi‑liquid product the far‑forward pivot point and the large drain valve with strainer are the two handling routes: controlled tilting for bulk decanting and a valved draw‑off for portioning.

The carcass is built in stainless steel 1.4301 (AISI 304) throughout, with a self‑supporting closed construction that carries the pivoted vessel within the frame. The kettle vessel is pivot‑mounted left and right within that frame, so the load is balanced over the body rather than cantilevered off one side. A double‑walled hinged lid with swivel joint and condensate drip strip keeps steam and condensate inside the cooking zone and channels condensate away from the operator when opened, while the product temperature control allows cooking to a set value rather than running entirely by eye.

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
• Kettle vessel pivot-mounted left and right within the frame
• Far-forward pivot point for controlled pouring
• 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 150 litre, 41 kW body is the right choice where the galley has a steady demand for boiled or simmered product at scale and enough electrical and steam capacity to support the 0,5–0,8 steam pressure band. It is less suitable for very small complements or pan work that rarely exceeds a few tens of litres, where a smaller kettle in the same family or a multifunctional pan would avoid heating volume that is never used.
