Miele Tumble Dryer PDR 507 HP [MAR] – 7 kg, 230V~ 60HZ, Lotus white

A 7 kg load in a 130 litre drum, dried on just 1.2 kW of connected load: the PDR 507 HP [MAR] is Miele’s compact heat‑pump dryer for marine and offshore use. With a maximum evaporation capacity of 2.7 l per hour and a quoted programme time of 67 minutes for normal cottons at 48% residual moisture, it is a low‑power solution where electrical capacity is tight.

The electrical connection is 230V~ 60HZ, which matches the small‑laundry circuits commonly provided in crew areas and offshore accommodation rather than the main 3‑phase galley bus. At a maximum floor load of 920 N and a footprint of 596 x 777 mm, this front loader can be planned into a laundry that has little deck area left once circulation and sorting space are drawn. Heat dissipation into the room is 3.6 MJ/h, a number the HVAC designer will factor into the laundry ventilation rather than discover during commissioning.

Specific energy consumption is given as 0.2 kWh/kg on the cottons/normal programme at 48% residual moisture and 0.17 kWh/kg on the mixed fabrics/normal programme at 40% residual moisture. That is where the heat‑pump system matters: the refrigerant circuit, charged with 0.59 kg of R134a, recovers heat instead of exhausting it, which is reflected in the appliance global warming potential of 844 kg CO2e. Programme times follow suit: 67 minutes for cottons at 48% residual moisture and 57 minutes for mixed fabrics at 40% residual moisture. For a chief housekeeper, that defines how many 7 kg batches per watch the space can realistically process.

Physically, the machine sits at 850 mm height with a 596 mm width and 777 mm depth. Door opening diameter is 370 mm with a 167° opening angle on a left‑hand hinge, so loading bulky items into the 130 litre drum is not constrained by the fascia. Net weight is 68.5 kg, gross 74 kg, which keeps handling straightforward during installation. Emission sound pressure level is quoted at ≤70 dB(A) re 20 µPa, relevant where the laundry is adjacent to cabins.

The machine is specified for offshore installations, specified and approved for shipboard use, and carries Lloyd's Register approval. With a recycling rate of 95%, it also speaks to end‑of‑life planning in regulated fleets.

This unit is a strong fit where a small crew laundry needs an electrically modest, 7 kg class dryer on a 230V~ 60HZ single‑phase feed, and where noise and heat rejection figures of ≤70 dB(A) and 3.6 MJ/h are acceptable to the accommodation layout. It is the wrong choice for a high‑throughput main laundry that has 3‑phase power and needs to turn over significantly more than 7 kg per cycle.
