Miele Tumble Dryer PDR 922 [EL SOM] – 22 kg, 3 AC 400V 50/60HZ, Stainless steel

Twenty-two kilograms of laundry on a 400 litre drum defines the PDR 922 as a high-throughput Benchmark-class dryer for larger shipboard laundries. With a published programme duration of 23 minutes and an exhaust-air design, it is built to clear a watch’s worth of work in a short window.

The electrical connection at 3 AC 400V 50/60HZ means this [EL SOM] variant can follow the vessel between 50 Hz and 60 Hz grids without changing hardware, which matters on ships that see both yard and operational supplies. Total connected load is 23.5 kW with a 22.5 kW electric heater rating and a 63 A fuse rating, so the laundry switchboard and load-shedding strategy need to reserve that capacity. Net weight is 198.9 kg with a maximum floor load of 2521 N, a figure a naval architect can take straight into deck-structure calculations.

External dimensions are 906 mm wide, 1400 mm high and 1162 mm deep, with gross shipping dimensions of 1090 × 1526 × 1254 mm. That footprint suits a dedicated laundry room rather than a narrow corridor, and the 520 mm door opening with a 180 degree door swing makes loading bulky items like synthetic duvets or over jackets straightforward. Heat dissipation into the room is quoted at 2.6 MJ/h, so the dryer adds a defined, modest load to the ventilation and HVAC calculation rather than becoming an unknown heat source in an enclosed space.

Capacity figures are given not just in kilograms but in concrete items: up to 3 synthetic duvets, 4 down pillows or 364 cloths at 22 g per batch. For cleaning contracts aboard, the published capacities of 84 cotton mops at 40 cm or 133 microfibre mops at 40 cm tell you how many decks’ worth of gear can be turned around in one cycle. Summer horse blankets, respirator masks and overalls are also listed, underlining that this 22 kg machine is sized for mixed hotel and technical textiles on larger vessels.

Specific energy consumption is stated at 0.5 kWh/kg, with a maximum evaporation capacity of 22.3 litres per hour. Coupled with a service life rating of 40000 drying cycles, this positions the PDR 922 for continuous daily use over many years rather than as a light-duty unit. Emission sound pressure level is 62 dB(A) re 20 µPa, which keeps noise in a working laundry to a level that crew can share the space with. A recycling rate of 91 % speaks to end-of-life planning in fleets with environmental reporting obligations.

This dryer is the right choice where a vessel needs fast 23 minute turnaround on 22 kg Benchmark loads and has an exhaust duct and 3 AC 400V 50/60HZ supply available. It is less suitable where hull penetrations for exhaust air are constrained or where only a smaller laundry with lower connected load is envisaged; in those cases a lower-capacity unit or a different drying system would fit better. Ordered under Miele material number 11911180, designation PDR 922 [EL SOM].
