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

Twenty‑two kilograms at a 1:18 load ratio on a 400 litre drum puts the PDR 922 [EL SOM] into the upper Benchmark class for shipboard dryers. With a programme duration of 23 minutes and an exhaust air system, it is specified for offshore installations where fast turnaround of workwear and linen is a daily requirement.

On a vessel, the electrical and structural figures on this machine decide where it can sit. Total connected load is 23.5 kW on a 3 AC 400V 50/60HZ supply with a 22.5 kW electric heater rating and a 50 A fuse rating, so the laundry switchboard and cable run have to be sized accordingly. Net weight is 198.9 kg with a maximum floor load of 2521 N, which a naval architect can check against the deck design before committing to the position. Heat dissipation into the room is quoted at 2.6 MJ/h, a number that belongs in the HVAC calculation for an enclosed laundry.

The external dimensions are 906 mm wide, 1400 mm high and 1162 mm deep, with gross dimensions of 1090 × 1526 × 1254 mm for transport and installation planning. A door opening of 520 mm and a 180 degree door opening angle on a left‑hinged front make sense of the listed item capacities: at the 1:25 load ratio the machine takes 16 kg, and the catalogue examples range from 16 respirator masks through 84 cotton mops at 40 cm to 364 cloths at 22 g. The same drum volume will also handle 3 overalls, 5 over jackets or 2 synthetic duvets per cycle, which is the pattern on many offshore and navy contracts.

Drying performance is defined by the residual moisture controlled user interface and a specific energy consumption of 0.5 kWh/kg. Maximum evaporation capacity is 22.3 litres per hour, which sets the requirement for the exhaust air duct and the room ventilation. Emission sound pressure level at the workplace is quoted as 62 dB(A) re 20 µPa, a figure that matters in compact laundries adjacent to accommodation spaces. Service life is specified at 40000 drying cycles, which is a planning number for operators running multi‑shift laundries.

Build and control

• Specified for offshore installations
• Specified and approved for shipboard use
• Remaining cycle time display
• Communication slot for network modules
• Prepared for a payment system (self-service laundries)
• Optical service interface for diagnostics
• Can be tied into a peak-load / energy management system
• WiFi networking
• Connector Box for external systems

Control is via the M Touch Pro system, programmable and residual moisture controlled, with a remaining cycle time display so crew can plan around the 23 minute programme duration. The communication slot, WiFi networking and Connector Box give options to tie the dryer into a peak‑load or energy management system and to integrate it into a wider shipboard network. Preparedness for a payment system makes this unit relevant for ferries or offshore accommodation vessels running self‑service laundries, where accountability per cabin or contractor is required.

This is the right choice where a laundry needs Benchmark Performance Plus throughput and has the electrical and exhaust air infrastructure for a 23.5 kW vented dryer. It is the wrong choice for spaces that cannot easily route exhaust air ducting or where the available supply cannot support a 50 A, 3 AC 400V 50/60HZ connection; those installations should be looking at other configurations in the same family.
