Miele Tumble Dryer PDR 514 ROP [EL SOM] – 14 kg, 3 AC 400V 50/60HZ, Iron grey

Fourteen kilograms nominal load in a 250 litre drum puts the PDR 514 ROP [EL SOM] into the workhorse slot of a shipboard laundry rather than the small-utility end. A 24 minute programme duration at a specific energy consumption of 0.53 kWh/kg gives a predictable balance of throughput and electrical demand when planning shifts and generator loading.

On a vessel the interface with the ship’s systems is as important as the laundry figures. This tumble dryer is specified and approved for shipboard use and for offshore installations, so the published numbers can be carried straight into design calculations. The electrical connection is 3 AC 400V 60 HZ with a total connected load of 14.1 kW and a 25 A fuse rating, so it sits comfortably on a standard marine distribution board. Heat dissipation into the room is 3.9 MJ/h, which is the figure the HVAC designer needs to dimension make‑up air and extraction in an enclosed laundry.

The unit is a front loader from the Benchmark Performance range with an iron grey front and stainless steel fascia, using an exhaust air drying system. External dimensions of 906 mm width, 852 mm depth and 1400 mm height define the deck footprint and allow it to stand under a modest deckhead. Gross dimensions of 1090 × 938 × 1526 mm matter when checking doorways and lifts during installation. With a net weight of 160.4 kg and a maximum floor load of 2024 N, the structural engineer has clear data to verify deck loading and any need for local stiffening.

For operators, access and cycle control are the key points. The 520 mm door opening with a 180 degree opening angle and left-hand hinge makes loading and unloading straightforward, including large flatwork or duvets. The M Select Benchmark control system with residual moisture controlled user interface keeps drying tied to target moisture rather than just elapsed time, which protects textiles and keeps energy use close to the quoted 0.53 kWh/kg. Maximum evaporation capacity is 13 litres per hour, and at a 1:18 load ratio the machine is rated for a 14 kg load, with a 10 kg load at a 1:25 ratio available where more delicate handling is needed. A service life of 40000 drying cycles indicates that this is built for continuous daily operation rather than occasional use.

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

This dryer is the right choice for a vessel with a dedicated laundry that can provide a 3 AC 400V 60 HZ supply and accept a 14.1 kW exhaust air load plus 3.9 MJ/h heat into the room. It is the wrong choice where running exhaust ducting is not possible or permitted, because the exhaust air drying system expects a proper duct to move its maximum evaporation capacity of 13 litres per hour out of the space. It is also the wrong fit for very occasional or light-duty laundries where a 14 kg Benchmark machine and a 40000 cycle service life would never be approached.
