DH-D-138BD Commercial Dehumidifier

The DH-D-138BD is the larger of the two commercial models with a full parameter block: a commercial-grade portable dehumidifier for high-humidity commercial and industrial settings, published on the 138 litre-per-day page. It is a different model from the DH-D-138BD1 summary-table row, and the two are never merged on this site.

Parameter block — detail page

The table below is the parameter block from the DH-D-138BD detail page, reproduced with the same fields and figures. The capacity row states 2.3 litres per hour, which is the parameter-block value; the page's title and feature row state the daily figure of 138 litres per day, and the two are kept in their own places on this page, because the page states no test conditions under which one could be derived from the other. The power rows state 1250 watts rated and 1750 watts maximum, which are the detail-page figures for this model: the summary table's DH-D-138BD1 row reads 1200 watts and 150 to 250 square metres, and those are a different model's figures, not this model's.

Features, quoted as page claims

The detail page describes a commercial-grade portable dehumidifier for high-humidity commercial and industrial settings, with a smart digital control panel, a high-capacity water tank with a drainage outlet, heavy-duty wheels and a handle, and states that it prevents mold, mildew and condensation damage. Its feature table carries the same five rows as the smaller commercial page, with moisture removal of up to 138 litres per day in the first row: the same 8-or-more-years casing claim, the same 30 to 80 percent relative humidity panel range, and the same 15 to 20 percent energy-saving claim. Those are the page's claims, quoted as such. This page has no water-drawer feature row: the integrated water collection drawer is a feature of the smaller model only, and it is not transferred here. The handle and heavy-duty wheels are this page's own description of the unit's mobility, and they are quoted as such.

A different model from the DH-D-138BD1

The distinction between this model and the DH-D-138BD1 deserves its own section, because the names differ by one character and the figures are close enough to confuse. The detail-page DH-D-138BD reads 1250 watts rated power, 1750 watts maximum, and an applicable area of 130 to 170 square metres, with a parameter-block capacity of 2.3 litres per hour. The summary-table DH-D-138BD1 reads 1200 watts, 1750 watts maximum, and 150 to 250 square metres, with a capacity of 138 litres per day. The maximum power figures agree, and that agreement does not collapse the two models into one: the rated power and the area differ, the capacity units differ, and the sources differ — a detail page against a summary-table row. This site keeps them on separate pages and in separate table rows, and a buyer must quote the full model name, including the 1 suffix or its absence, in any inquiry. An inquiry that quotes only 138BD leaves the supplier to guess which model is meant, and guesses get installed.

Applications listed on the detail page

The detail page lists the same five applications as the smaller commercial page: warehouse storage in Southeast Asia, factory production areas including textile mills and electronics factories, basements in commercial buildings, food processing plants, and pharmaceutical storage warehouses. The page description adds basements, factories, storage rooms and data centers as settings where the unit serves. Those lists are the whole of the application evidence for this model. The applicable area of 130 to 170 square metres is the figure the parameter block states, and it is the figure to use when checking coverage — not the 150 to 250 square metres of the DH-D-138BD1 table row, which belongs to the other model. A space larger than the stated area, or a space with a heavier humidity load, is a question for the inquiry, with the space and its use described.

Operating conditions

The operating temperature range is 5 to 38 degrees Celsius, and the circulating air volume is 750 cubic metres per hour. Both figures are parameter-block values, and both bound the model's use: no performance figure is published for operation outside the stated range. The power supply is 220 volt single-phase at 50 hertz, with a rated current of 5.7 amps, and the package size is 556 by 495 by 1073 millimetres. The unit stands taller than the smaller commercial model, which matters where ceiling height or door clearance is tight, and the package size is the figure to check against the access route, not an installed footprint the page does not state. Fixing, ducting, drainage routing and control wiring are not described on the page, and they belong in the inquiry.
