Miele Washing Machine PWM 935 [EL DV DD SOM] – 35 kg, 3 AC 400V 50 HZ, Stainless steel

Thirty‑five kilograms per charge in a 320 l drum places the PWM 935 at the heavy end of a shipboard laundry. A 1:9 load ratio with a 415 mm door opening that swings through 180° lets full bags of linen, mops or PPE go straight in rather than be fed piecemeal.

This model is specified and approved for shipboard use and specified for offshore installations, so it fits projects where documented suitability is part of the approval trail. Electrical connection is 3 AC 400V 60 HZ with a total connected load of 31.6 kW and a 63 A fuse rating, figures that have to be allocated on the vessel’s low‑voltage switchboard. Net weight is 665 kg with a maximum floor load of 9540 N, so the installation point needs structure beneath it, not a light raised floor. Heat dissipation into the room is 6.1 MJ/h, which has to sit in the HVAC calculation for an enclosed laundry.

On the wash side, the PWM 935 couples defined resource use with high extraction. Spin speed is 1060 rpm with a g factor of 502, yielding residual moisture of 51 % after a cold rinse and 44 % after a hot rinse; when processing cleaning cloths the value drops to 14 %. That level of dewatering shortens dryer time and cuts the electrical and thermal load demanded from downstream equipment. With a cold water connection the standard cycle draws 262.5 l and 7.6 kW with a programme duration of 61 minutes; the corresponding figures with hot water are 261.6 l and 2.16 kW in 49 minutes. Specific consumption is 7.5 l/kg and 0.22 kWh/kg on a cold connection and 7.5 l/kg and 0.06 kWh/kg on a hot connection, so where the ship’s plant can provide hot water those lower kWh values are worth planning around.

The ECO programme provides shorter, leaner cycles. With a cold water connection it uses 242 l and 5.3 kWh in 44 minutes; with hot water 243.6 l and 0.76 kWh in 37 minutes. For cleaning contractors aboard, the Mops standard 60 °C programme is documented at 422.3 l and 7.95 kWh with cold water in 59 minutes, or 427.3 l and 2.59 kWh with hot water in 52 minutes. A thermal disinfection rinse programme, independently tested virucidal efficacy and verified hygiene performance are backed by continuous wash temperature monitoring and the EcoSpeed wash rhythm for reduced water use over the machine’s 30000 tested operating hours.

In practical loading terms, the published capacities are explicit: up to 800 cloths at 22 g, 184 cotton mops at 40 cm / 190 g, 159 cotton mops at 50 cm / 220 g, 292 microfibre mops at 40 cm / 120 g, or 206 microfibre mops at 50 cm / 170 g fit per cycle. For PPE and cabin textiles the machine is rated to 26 respirator masks, 10 helmets, 6 overalls, 9 over jackets, 4 chemical protection suits, 4 synthetic duvets, 8 synthetic pillows, 4 down duvets, 8 down pillows and 5 summer horse blankets.

This unit is the right choice where a vessel needs documented disinfection programmes, heavy daily throughput and a single 35 kg machine rather than several smaller units. It is the wrong choice for a small shipboard laundry handling only light cabin‑linen volumes, where a lower‑capacity washer would free space, reduce the 9540 N maximum floor load and avoid allocating 31.6 kW on the board.
