Marine Tumble Dryers

Benchmark dryers up to 44 kg and 37.7 kW

Most of the work on this page is done by the Miele Benchmark series. These dryers cover electrical powers from 4.6 to 37.7 kW, drum volumes from 180 to 800 litres and widths from 700 to 1206 mm. Where stated, Benchmark loads run up to 44 kg, with net weights as high as 294.3 kg, so they are a structural item in the laundry, not a movable appliance.
On a vessel these figures translate into deck loading and service routing questions before model choice. The largest, a 37.7 kW PDR 944 on 400 V at 50/60 Hz, needs planning around the existing switchboard, and its footprint and weight have to sit inside the laundry’s coaming and stiffener pattern. Benchmark models also all carry “marine approved”, “offshore specified”, “network connectable”, “payment system ready” and “energy management ready” flags, which matters if the operator wants central consumption logging or token-based crew use.

Little Giants down to 1.2 kW and 7–8 kg

The Little Giants series sits at the small end of this page: 1.2 to 6.4 kW connected load, 130 litre drum and 7 to 8 kg rated load across all models, in a width band from 596 to 606 mm and net weights from 49 to 72 kg. That footprint fits laundries built around standard 600 mm modules, narrow corridors and stacked washer-dryer arrangements.
In electrical terms Little Giants give the naval architect more options. Supply voltages include 208–240 V on some units, 230 V, 400 V and 400–480 V, with 60 Hz on most of the series and 50 Hz on a majority. That allows these dryers to follow the vessel’s system design instead of forcing a special transformer. They are all marine approved, offshore specified, network connectable and payment system ready, while energy management readiness appears on a subset where tighter consumption control is required.

Vented vs heat pump for shipboard laundries

The category splits into vented and heat-pump dryers, with most listings vented and six models specified as heat pump with no vent. Vented units push their moist exhaust out through ductwork sized to the machine, while heat-pump models keep a closed air loop and reject their moisture through a condensate stream. For a ship laundry that is already struggling with HVAC capacity, the difference between an exhaust duct and a drain line defines the installation route.
Heat-pump dryers on this page include the 7 kg PDR 507 HP and 8 kg PDR 908 HP. Removing the exhaust duct removes a hull or superstructure penetration and a duct run through fire zones, at the cost of a condensate drain, which is often the easier route on a vessel where the laundry shares air-handling with accommodation.

Matching supply voltage, frequency and width

Across all 42 products the electrical spread runs from 1.2 to 37.7 kW, with published supply voltages including 230 V, 400 V, 400–480 V, 440 V and 208–240 V. Supply frequency covers 50 Hz on most models and 60 Hz on almost all, with Benchmark specifically carrying both 50 and 60 Hz across its range. Every Benchmark dryer names both frequencies, which makes that series the simpler choice for a fleet running both.
Physically, widths start at 596 mm and run through to 1206 mm. Drum volumes move from 130 litres on Little Giants to 800 litres on the largest Benchmark machines, and stated loads where given sit between 7 and 44 kg. Net weight ranges from 49 to 294.3 kg, so the foundation needs to consider not just the footprint but also the load from a rotating drum in a seaway.

When to look at Washing Machines or Ironers instead

This tumble dryer page is the right place for specifying how washed laundry is dried, but it does not cover the upstream and downstream parts of the process. If the project needs to size washer-extractors to feed these dryers, the Washing Machines category carries the Miele washer-extractors from the same Little Giants and Benchmark series. If the requirement is finishing flatwork after drying, the rotary ironers in the Ironers category are the relevant equipment, and where deck area is tight but both washing and drying are required in one column the Washer-Dryer Stacks page holds the PDW stacks.
By keeping dryer selection on this page focused on load size, width, vented versus heat pump and the vessel’s voltage and frequency, and using the sibling Laundry Equipment categories for washing and finishing, the galley or hotel laundry can be laid out with predictable flows and electrical diversity instead of trying to solve everything with one appliance type.
