Miele Tumble Dryer PDR 914 [EL SOM] – 3 AC 480V 50/60HZ, Stainless steel

A 250 litre drum with a quoted 14 kg load at a 1:18 ratio gives the PDR 914 [EL SOM] the scale for a main shipboard laundry rather than a small crew-only space. The nominal 10 kg figure at a 1:25 ratio shows where it can be run conservatively if the textile mix or duty calls for it.

On board, drying capacity is set by moisture removal and heat rejection as much as by drum size. This exhaust air dryer is rated for a maximum evaporation capacity of 13.3 litres per hour, so the laundry ductwork and make-up air have to be planned around that figure. Heat dissipation into the room is 3.9 MJ/h, and the emission sound pressure level is 51 dB(A) re 20 µPa, numbers that matter when the laundry sits close to accommodation or workspaces where noise and heat have to be controlled.

The electrical configuration is aligned with marine switchboards: 3 AC 440V 50/60HZ, with a total connected load of 14.1 kW. Electric heater rating is 15.9 kW and a separate heater rating is quoted at 13.5 kW, protected on a 25 A fuse. Being able to tie the dryer into a peak-load or energy management system means that 14.1 kW draw can be coordinated with other hotel and galley consumers instead of appearing as an unmanaged spike on the laundry panel.

Physically, the machine is a front loader in stainless steel with external dimensions of 1400 × 906 × 852 mm (H×W×D). Transport and routing are set by gross dimensions of 1526 × 1090 × 938 mm. Net weight is 160.4 kg, with a maximum floor load of 2024 N; those values give the design office enough to sign off the deck structure. A 520 mm door opening and 180 degree door swing on a left hinge make it possible to handle large duvets, overalls and mops without fighting the door, provided the surrounding space is planned accordingly.

Operationally, the dryer sits in the Benchmark series and the Performance Plus range, with the M Touch Pro control system and a residual moisture controlled interface. Programme duration is listed at 24 minutes, and the specific energy consumption is 0.51 kWh/kg, so a laundry planner can translate duty into kWh over a day. Service life is specified at 40000 drying cycles. The published recycling rate is 92 %, which helps when end-of-life documentation and waste plans are part of the vessel specification. The capacity table is explicit: from 8 respirator masks or 1 set of overalls through 2 summer horse blankets, 255 cloths at 22 g, 83 microfibre mops at 40 cm or 59 microfibre mops at 50 cm, the planner can see real textile loads rather than abstract kilograms.

This dryer fits where a vessel has a 3 AC 440V 50/60HZ supply, an established exhaust-air duct route and a steady flow of 10–14 kg batches to exploit a 24 minute cycle. It is the wrong choice where exhaust air ducting cannot be provided or where even 3.9 MJ/h of heat into a confined, unconditioned room would overload the space; in that case a different drying system and load class should be specified.
