Miele Rotary Ironer PRI 318 [EL SOM LAM IB RF] – 3 AC 400V 50-60HZ, Octoblue

A roller diameter of 300 mm and a working width of 1,750 mm place the PRI 318 in the higher-output class of rotary ironers. At 25 % residual moisture it is rated for up to 87 kg/h, and even at 50 % residual moisture it still delivers 51 kg/h, which is the more realistic condition for shipboard flatwork.

For a laundry designer on a vessel, the electrical and structural figures decide whether this model fits the space. The PRI 318 connects at 3 AC 400V 50–60HZ with a total connected load of 18.3 kW and a fuse rating of 35 A, so it can be integrated into a common 400 V hotel-load distribution. Heat dissipation into the room is specified at 10.8 MJ/h, a number that belongs in the HVAC calculation for an enclosed laundry. Net weight is 415 kg, with a maximum floor load of 4,071 N, so the deck structure and any raised steel plinth can be checked early with the yard.

Physically the machine stands 1,110 mm high, 2,469 mm wide and 1,377 mm deep. Those dimensions, together with the construction type “laundry infeed at the front, laundry outfeed at the back”, mean it needs clear space both sides of the roller and a rear collection zone; it is not a single-operator return-feed layout. Gross dimensions of 1,388 × 2,576 × 1,096 mm give a realistic envelope for getting the machine through doors and up companionways in the crate.

The PRI 318 is built for long service intervals rather than frequent replacement. Tested operating hours are quoted at 20,000, and the recycling rate is given as 98 %, which is relevant for shipowners working under corporate sustainability metrics and end-of-life planning. Emission sound pressure level at the workplace is 56 dB(A) re 20 µPa, low enough that it will not dominate a shared laundry space.

On the linen side, the machine uses leaf-spring padding under an ARAMID needle-felt cloth ironer cover, giving the pressure and heat transfer needed for consistent finish across the 1,750 mm width. Ironing speed is electronically controlled between 1.2 and 4.6 m/min via the touch display control system, with defined programme parameters set on screen, so crews can match speed and temperature to linen types within a stable, repeatable range.

• Laundry infeed at the front, laundry outfeed at the back
• Outer casing in Octoblue

The PRI 318 suits ships with a continuous flow of flatwork and enough deck area to allocate a through-feed ironer plus a separate collection side. It is less suitable where the laundry must be strictly single-operator, or where the available electrical capacity cannot support an 18.3 kW connected load.
