Miele Rotary Ironer PRI 318 [EL SOM LAM IB RF] – 3 AC 230V 50-60 HZ, Octoblue

A 300 mm roller and 1,750 mm working width put the Miele PRI 318 into the high-output class for shipboard flatwork. At 25 % residual moisture it is rated up to 87 kg/h, and at 50 % residual moisture still delivers 51 kg/h, so a vessel’s linen flow can be sized against hard numbers rather than guesswork.

On board, that throughput figure feeds directly into berth count, changeover rhythm and the way the laundry is staffed. A machine that can process 87 kg/h at 25 % residual moisture gives headroom for cabin, restaurant and spa linen without driving the laundry into continuous night operation. The controlled ironing speed range from 1.2 to 4.6 m/min lets the operator slow the bed down for heavy, damp items or run faster when the washers are delivering closer to 25 % residual moisture.

The PRI 318’s external dimensions of 1110 x 2469 x 1377 mm (H x W x D) define the zone that has to be kept clear in the laundry plan, with front infeed and rear outfeed calling for safe access both sides. Gross dimensions of 1388 x 2576 x 1096 mm are the figures that matter for getting the machine through doors and corridors from quay to final position. Net weight is 415 kg, and maximum floor load is 4071 N, so the deck structure and any raised platform or coaming have to be checked against those published loads. Heat dissipation of 10.8 MJ/h into the room is a planning point for the HVAC designer, because that energy ends up in the laundry’s air-handling calculation rather than just the equipment list.

Electrically, the unit is specified at 3 AC 208 V 50–60 Hz, with a total connected load of 16 kW and an electric heater rating of 15.4 kW. Fuse rating is 50 A. That combination requires its own protected circuit on the ship’s distribution board, and the dual 50–60 Hz specification aligns with typical vessel supplies without conversion. Emission sound pressure at the workplace is quoted as 56 dB(A) re 20 µPa, which matters where the ironer runs for long stretches in a confined laundry.

On the ironing side, leaf-spring padding under an ARAMID needle-felt cloth gives a defined, resilient support across the 1,750 mm width. The control system is a touch display with setting of defined programme parameters, so target temperature and speed settings can be stored and repeated between shifts. Tested operating hours are stated at 20000, which is the scale of duty a superintendent expects from plant intended for continuous professional service.

The PRI 318 is a realistic choice where there is sustained flatwork volume, enough floor space for a 2469 mm-wide machine with rear access and an electrical plant that can support a 16 kW, 3 AC 208 V 50–60 Hz load. It is the wrong choice for very small crew-only laundries with intermittent use, or for spaces that cannot provide safe working clearance at both the front and rear.
