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

Thirty‑five kilograms at a 1:9 loading ratio on a 320 litre drum puts the PWM 935 into full hotel, ferry or offshore camp territory rather than a small crew laundry. A g‑factor of 502 at 1,060 rpm gives residual moisture down to 43 % on a hot rinse and 50 % on a cold rinse, which shortens drying time and keeps the laundry line moving.

This model is specified and approved for shipboard use and for offshore installations, so its hygiene and mechanical package are aimed at continuous operation under inspection. The electrical connection is 3 AC 400V 60 HZ with a total connected load of 6.1 kW and a 16 A fuse rating, figures that sit comfortably on a low‑voltage switchboard. A maximum floor load of 9,540 N and a net weight of 665 kg give the naval architect defined values for deck design and support.

On throughput, the standard programmes set the rhythm. With a cold water connection the main programme runs for 52 minutes using 238.6 litres and 6.34 kW; adding hot water shortens this to 47 minutes with 226.5 litres and 1.75 kW. In ECO, cycles fall to 39 minutes on cold and 34 minutes with hot, with water consumption trimmed to 224.4 litres and 217.4 litres respectively. Specific consumption is 6.8 l/kg and 0.18 kWh/kg on a cold feed, and 6.5 l/kg and 0.05 kWh/kg on hot, so fresh‑water production and electrical load can be budgeted at concept stage.

For hygiene‑critical work the Mops standard 60 °C programme is the reference point. On a cold water connection it runs for 53 minutes and uses 392.5 litres and 7.2 kWh; with hot water the figures are 46 minutes, 404.2 litres and 2.61 kWh. Residual moisture when processing cleaning cloths is quoted at 12 %, which matters where mops and cloths have to return to service quickly. The machine is tested for 30,000 operating hours, a span that, on many vessels, will run across several dry‑dock cycles.

External dimensions are 1,646 mm high, 1,090 mm wide and 1,275 mm deep, with gross shipping dimensions of 1,793 × 1,365 × 1,425 mm. The door opening is 415 mm in diameter with a 180 degree opening angle and a right‑hand hinge, so the layout must allow full swing and clear loading space. Heat dissipation into the room is 6.1 MJ/h and the emission sound pressure level at the workplace is 71 dB(A) re 20 µPa; both numbers go straight into HVAC and acoustic calculations for an enclosed laundry.

Miele also publishes practical load guidance. One cycle can take 800 cloths at 22 g, 184 cotton mops at 40 cm / 190 g or 159 cotton mops at 50 cm / 220 g. For personal protective equipment, the figures are 26 respirator masks, 10 helmets, 6 overalls, 9 over jackets and 4 chemical protection suits. Bedding examples include 4 synthetic duvets with 8 synthetic pillows, or 4 down duvets with 8 down pillows, plus 5 summer horse blankets.

This machine is the right choice where a vessel needs genuine 35 kg capacity with low residual moisture and documented hygiene performance in a dedicated laundry space. It is the wrong choice for a small crew or workboat installation where a 1,275 mm depth, 1,646 mm height and 9,540 N floor load cannot be accommodated in the structure or through the access routes.
