Miele Tumble Dryer PDR 910 [EL SOM] – 3 AC 440V 50/60HZ, Stainless steel

A 180 litre drum, a 440 mm door opening and a 44 minute programme time set the working profile of the PDR 910 [EL SOM]. At a 1:18 load ratio the unit is rated for 10 kg, while 8 kg at 1:22.5 is available where the laundry is run with lighter process loads.

This model is specified and approved for shipboard use and explicitly listed for offshore installations, so its exhaust-air system and performance data can be written directly into a vessel specification. Maximum evaporation capacity is 7.4 l per hour, which is the figure that drives exhaust duct sizing and make-up air planning alongside the electrical feed. Heat dissipation into the room is 3.9 MJ/h; in a small, enclosed laundry that value sits straight in the HVAC calculation and can be compared with other heat sources on the same deck.

The machine sits in Miele’s Benchmark series at the Performance Plus range, with an M Touch Pro control system that is fully programmable and runs residual-moisture-controlled drying. Specific energy consumption is stated at 0.51 kWh/kg; combined with the 10 kg load rating, this gives a clear planning basis for power budgeting over a typical duty cycle. Total connected load is 4.6 kW, with an electric heater rating of 5.18 kW and a separate heater rating of 4.26 kW, all protected on a 10 A fuse. The electrical connection on this variant is 3 AC 400 V 50/60 Hz, so the supply and protection requirements are explicit for the switchboard designer.

Externally the cabinet stands 1020 mm high, 700 mm wide and 763 mm deep. Net weight is 72 kg, with a maximum floor load of 853 N, so the dryer is straightforward to place on lighter decks once correctly fixed, and the published load allows a naval architect to check local scantlings. Gross shipping dimensions of 1215 × 760 × 820 mm and a gross weight of 80 kg are primarily relevant during logistics and warehousing. Emission sound pressure is quoted at 50 dB(A) re 20 µPa, which matters where the laundry shares a bulkhead with accommodation or office spaces.

Miele publishes loading guidance by item count as well as kilograms, which is useful on vessels with a high proportion of workwear and cleaning textiles. A full charge can be built from 182 cloths at 22 g, or from 42 cotton mops at 40 cm or 36 cotton mops at 50 cm. Alternatives include 66 microfibre mops at 40 cm, 47 microfibre mops at 50 cm, or 100 office mops at 100 g. For protective equipment and bedding, a load can comprise 4 respirator masks, 1 overall, 2 over jackets and 2 summer horse blankets, or combinations such as 1 synthetic duvet and 2 synthetic pillows, or 1 down duvet and 2 down pillows.

The front and fascia are finished in stainless steel, which suits typical cleaning regimes in a professional marine laundry. A recycling rate of 90% is quoted, which is relevant where an owner has end-of-life and sustainability targets documented in a newbuild or refit brief.

This dryer suits Benchmark-class workloads where an exhaust duct route is available and a 3 AC 400 V 50/60 Hz supply is present on the switchboard. It is the wrong choice where yard standards or flag-state rules rule out exhaust-air ductwork from the laundry and require a non-vented solution instead.
