MKN Electric Boiling Kettle 7EKER080D

Ninety litres nominal volume with an 80 litre recommended fill positions the 7EKER080D as a medium production kettle for a single cooking station. A DIN cooking time of 25 min gives a concrete figure for planning how fast that 80 litre working load can be brought up.

On a ship this capacity-to-time combination links directly to both the electrical distribution and the HVAC calculation. The kettle is rated at 15.8 kW and connects to a 3 N−PE AC/50 Hz supply at 380–415 V, protected at 3×32 A. That puts it firmly in the three-phase cooking load group that has to be scheduled on the main galley board, not on a light-duty sub-panel. Latent heat emission is quoted at 3160 W with 553 W of sensible heat; if that load is not allowed for in the galley extraction and air-conditioning design, it will show up as temperature and humidity around the cooking line. The IPX6 protection rating aligns with wash-down routines where equipment is cleaned in place with spray hoses rather than wiped by hand.

The inner kettle geometry is defined as 500 mm diameter and 477 mm depth, which yields the 90 litre gross volume while leaving realistic freeboard at the 80 litre recommended fill. That free height is what keeps product in the kettle as it reaches a rolling boil and gives margin when the vessel moves. The 25 min DIN cooking time is achieved with the VAPRO heating system and separate steam generator transferring heat through the jacket wall, rather than direct immersion of elements in the product. For a chef or superintendent building a menu cycle, that time value is what determines how many batches can be turned in a watch.

Net weight is 110 kg and gross weight 119 kg. Those numbers are relevant both for deck loading checks in the galley and for logistics if the unit has to be craned aboard or moved through restricted access routes. The working area is specified as 1 kettle, so this is a stand-alone appliance rather than a multi-kettle battery on a shared frame.

Water supply is via a 3/4 ″ internal thread with a maximum flow rate of 80 l/min, designed for an inlet pressure between 2 and 6 bar. Where the ship’s potable water ring can deliver close to that maximum flow, the kettle can be filled quickly enough that fill time does not dominate the process; on restricted supplies the same connection and pressure range still give predictable performance. Connection size for the relevant outlet is stated as 1,5 ″, which should be built into the yard’s deck penetration and drainage drawings from the outset.

Build and control

• Fully welded seams
• Energy-efficient VAPRO heating system with separate steam generator
• IPX6 ingress protection for high-pressure cleaning

This unit is the right choice where an 80 litre working volume per batch fits the ship’s complement and a 15.8 kW, 380–415 V three-phase connection is available close to the cooking line. It is the wrong choice for very small crews where a kettle of this footprint and 90 litre capacity will rarely be used near its recommended fill, or for galleys constrained to lower electrical loads that cannot release a 3×32 A circuit to a single appliance.
