Miele Tumble Dryer PDR 908 [EL MAR 3 AC 400-480V 50-60Hz] – 8 kg, 400–480 V, Lotus white

Eight kilograms of quoted load on a 130 litre drum is the working pair that defines the PDR 908 EL MAR in a shipboard laundry. With a total connected load of 6.4 kW on a 3~ 480V 50/60HZ supply, it sits in the range many vessels reserve per dryer while still delivering a standard programme duration of 52 minutes.

This variant is specified and approved for shipboard use and specified for offshore installations, so the basic question of suitability at sea is settled at product level rather than by exception. Lloyd's Register approval gives class recognition on the equipment side; vent routing, exhaust termination and electrical protection remain installation decisions. A maximum floor load of 920 N and a net weight of 51.5 kg are low enough that the unit can often sit on a light deck without additional stiffening, but still need to be checked against the naval architect's load tables.

The machine belongs to the Little Giants series in the Performance Plus range and uses an exhaust air drying system. Specific energy consumption is quoted at 0.5 kWh/kg on the Cottons/Normal programme at 48 % residual moisture and 0.42 kWh/kg on the mixed-fibre Normal programme at 40 % residual moisture. Programme durations are 52 minutes for the cottons reference case and 47 minutes for mixed fabrics, with a maximum evaporation capacity of 4.8 litres per hour. Heat dissipation into the room is 0.76 MJ/h, which is modest but still part of the HVAC calculation when several dryers share a compact space.

Electrically, the PDR 908 EL MAR is an electric-heated front loader with an M Touch Flex control system. The electrical connection is specified as 3~ 480V 50/60HZ with a fuse rating of 10 A. Electric heater rating is 5.16 kW with an overall heater rating of 6.14 kW, the difference covering drives and control loads up to the 6.4 kW connected figure. Emission sound pressure level is given as ≤70 dB(A) re 20 µPa, which matters when laundry spaces back directly onto cabins or work areas.

Physically, the dryer stands 850 mm high, 596 mm wide and 717 mm deep. Gross shipping dimensions of 940 × 660 × 820 mm and a gross weight of 57 kg help with planning access routes from the stores to the laundry, including lifts and narrow doors. The door opening is 370 mm in diameter with a 167 degree opening angle and a left-hand hinge, detail that can decide whether loading is comfortable in a tight corner of the laundry. A recycling rate of 95 % is quoted, which may be relevant for operators tracking end-of-life recovery as part of their fleet standards.

The PDR 908 EL MAR is the right choice where an 8 kg exhaust air dryer matches the washer capacity and where an exhaust duct and overboard vent already form part of the design. It is the wrong choice for a fully closed laundry with no viable path for exhaust air, or for a vessel policy that rules out exhaust air systems entirely.
