Miele Tumble Dryer PDR 918 [EL SOM] – 3 AC 400V 50/60HZ, Stainless steel, Mat. no. 11911190

Eighteen kilograms at a 1:18 load ratio with a 23 minute programme time sets the PDR 918 [EL SOM] up for high-throughput duty in a shipboard laundry. A 325 l drum behind a 520 mm door opening takes that load in one go rather than splitting heavier batches across cycles.

On board, the electrical and HVAC figures are often the hard limits. This exhaust-air dryer is specified for 3 AC 400V 50/60HZ with an 18 kW electric heater rating and a total connected load of 18.6 kW, protected by a 50 A fuse rating. Maximum evaporation capacity is 18.5 l/hour and heat dissipation into the room is 4.5 MJ/h, which both feed straight into the ventilation and make‑up air calculation for a closed laundry space. The drying system vents moisture out of the compartment rather than into it, which matters in small, poorly ventilated laundries.

External dimensions are 906 mm wide, 1035 mm deep and 1400 mm high, so the dryer occupies modest deck area for its capacity, but still needs enough clearance in front for a 180° door opening and service access. A maximum floor load of 2212 N and a net weight of 173.5 kg give the design team concrete data for deck loading checks and for planning how to move the 187 kg gross weight through hatches and passageways using the 1090 x 1125 x 1526 mm crated dimensions. An emission sound pressure level of 50 dB(A) re 20 µPa keeps noise impact manageable where the laundry shares a compartment with other equipment.

Process figures are equally specific. Service life is stated at 40000 drying cycles, which aligns with multiple full loads per day over a long deployment. Specific energy consumption is 0.52 kWh/kg, tied to residual moisture controlled drying via the M Touch Pro control system rather than simple timer operation. The 13 kg rating at a 1:25 load ratio and the 18 kg rating at 1:18 help match the machine to real textiles: for example up to 295 cloths at 22 g, 68 cotton mops at 40 cm, or 186 office mops at 100 g in one load. The same data sheet lists 12 respirator masks, two overalls and three over jackets, or three summer horse blankets, as workable examples.

These concrete capacities matter aboard because laundry staff plan around batches rather than nominal kilogram figures. The loading examples for synthetic and down bedding — three synthetic pillows, three down pillows, one synthetic duvet and one down duvet — show where the 325 l drum volume meets bulkier items that often come from passenger areas or officer berths.

This dryer is the right choice where the vessel can provide a 3 AC 400V 50/60HZ, 18.6 kW exhaust‑air connection and needs fast 23 minute cycles on loads up to 18 kg. It is the wrong choice for laundries where running exhaust ducting for an exhaust air system is not possible or where the available electrical capacity cannot support a 50 A, 18 kW electric heater. Ordered under Miele material number 11911190 and article number 52918016SOM with designation PDR 918 [EL SOM].
