Marine Deep Fat Fryers

From 6 to 42 kW in Optima 850

The Optima 850 series stretches from 6 kW fryers suited to lighter duty up to 42 kW units carrying as much as 115 litres of oil, all at 400 V. That spread allows a single line to cover everything from a snack service to sustained production in a main galley, with widths running from 400 mm modules up to 1800 mm suites and net weights up to 180 kg to factor into deck loading.
For shipboard planners the key is aligning connected load, tank volume and footprint. A 42 kW, 115 litre Optima 850 module at 1800 mm width is a very different proposition from a slim module: it concentrates both weight and heat in one position and needs the electrical and extraction infrastructure to match.

Optima 700, HotLine and CounterSL in tighter spaces

Optima 700 and the HotLine and CounterSL ranges sit lower in capacity and footprint. Across Optima 700 the listed fryers run 6 to 20 kW, with 12.5 to 30 litres oil volume and widths between 400 and 600 mm; HotLine and CounterSL match that 6 to 20 kW, 12.5 to 30 litre band in 400 to 500 mm widths. Net weights here start from 19 kg and run into the 70 kg bracket, so two or three modules still stay manageable for lighter deck structures.
Every HotLine and CounterSL fryer lists fully welded seams and a drain valve; in Optima 700 all units have welded seams and just over half add a drain valve, and every HotLine fryer is also energy management ready. That combination matters in compact galleys where fryers sit shoulder to shoulder with other cooking equipment and where any oil handling or power peak has an immediate impact on the rest of the line.

Electrolux Professional 900XP and thermaline 90 on 440 V

The Electrolux Professional fryers in this category sit in the 900XP and thermaline 90 families. 900XP units bring net weights up to 115 kg, with supply options including 380–400 V and 400 V, and importantly some variants at 440 V with both 50 Hz and 60 Hz listed. thermaline 90 fryers are specified at 440 V as well, with published operation at 50 Hz or 60 Hz depending on model.
On a vessel with mixed 400 V and 440 V distribution, that native 440 V support avoids running key cooking loads through transformers. It also lets the cooking line follow the same 50/60 Hz pattern as other thermaline 90 and 900XP modules, simplifying switchboard and spare-parts planning.

Oil volume, zones and water cleaning in marine use

Across the whole page, stated fryer capacities range from 12.5 litres up to 115 litres and most models are either single-zone or two-zone units. One-zone fryers suit straightforward, high-throughput menus; two-zone variants allow separation of protein and allergen-heavy loads or staggering batch start times without adding another cabinet. Where multiple fryers are grouped, the energy-management-ready models in Optima 700, Optima 850 and HotLine can be planned so that peak demand is smoothed across the bank.
Shipboard cleaning practice drives the value of fully welded seams and washdown protection, both of which are common in the MKN ranges here. With many models listed as washdown protected, they can be integrated into wet-cleaned galley lines that already rely on pressure spray, as long as the surrounding fabrication and electrical terminations follow the same hygiene and IP logic.

When to specify Bratt Pans or Boiling Kettles instead

This page is the wrong place if the requirement is bulk production of stocks, soups or sauces, or shallow frying on a large plate. Deep fat fryers here top out at 115 litres oil volume; above that, or where direct boiling and braising are needed, the Bratt Pans and Boiling Kettles categories carry the load more effectively. Those lines also offer capacities up to and beyond 150 litres in single vessels, which is the scale required for central production on larger commercial vessels.
