Miele Tumble Dryer PDR 908 [EL MAR 3N AC 400V 50-60Hz] – 8 kg, 400 V, Lotus white

Eight kilograms per cycle on a 130 litre drum sets the working size of the PDR 908 EL MAR, with a quoted programme duration of 42 minutes on the Cottons/Normal programme at 48% residual moisture. Specific energy consumption for that cycle is 0.5 kWh/kg, so both time and energy per batch enter the laundry plan as fixed numbers.

This variant is specified and approved for shipboard use and specified for offshore installations, supported by Lloyd’s Register approval. That is relevant where class and flag ask for documented suitability instead of shore-only appliances. Heat dissipation into the room is given as 0.76 MJ/h with a maximum evaporation capacity of 5.5 litres per hour, so the designer can put concrete figures into the HVAC and exhaust calculation when the laundry is inside the accommodation block.

The dryer sits in Miele’s Little Giants series within the Performance Plus range. External dimensions are 850 × 596 × 717 mm (height × width × depth), compact enough for narrow laundry rooms or passage access while still providing a 370 mm door opening with a 167 degree opening angle on a left-hand hinge. Net weight is 51.5 kg with a maximum floor load of 920 N, and gross transport dimensions of 940 × 660 × 820 mm with a gross weight of 57 kg give the naval architect clear numbers for access routes and lifting points. Emission sound pressure level at the workplace is specified as ≤70 dB(A) re 20 µPa, useful where the laundry shares decks or bulkheads with accommodation spaces.

Electrically, this marine variant carries the designation PDR 908 [EL MAR 3N AC 400V 50-60Hz], while the data plate states an electrical connection of 3~ 230V 50/60HZ. Total connected load is 3.24 kW with an electric heater rating of 6.14 kW and a 16 A fuse rating, so the machine can sit on a moderate breaker. For mixed fibre fabrics on the Normal programme at 40% residual moisture, specific energy consumption is 0.42 kWh/kg with a 37 minute programme duration, allowing planning for typical workwear and mixed loads as well as cottons.

Control is via the M Touch Flex system on a programmable, residual moisture controlled interface. The drying system is exhaust air, so the published evaporation capacity and heat dissipation figures become ductwork and ventilation tasks rather than condensate handling inside the room. A recycling rate of 95% is quoted, relevant where the owner is tracking end-of-life recycling performance across the hotel load.

This unit is a good fit where 8 kg batches, a 42 minute cottons cycle at 0.5 kWh/kg and a 3.24 kW connected load match the duty profile, for example in smaller crew laundries or as a satellite machine serving a limited number of cabins. It is the wrong choice where the ship’s laundry has to move substantially larger loads per cycle, because the 8 kg rating and 130 litre drum volume limit throughput and point towards larger bodies instead.
