Large dehumidifiers size range from 1,000 SCFM to 3,999 SCFM
Dehumidifiers in this range are generally stationary and can used to dehumidify large storage areas, warehouses, large green houses, interior of large aircraft, series of storage containers or just about any large size storage area that needs protection for stored material from corrosion, mold, mildew and moisture damage. These units can usually dehumidify areas from 10,000 square feet up to 39, 900 square feet with a normal ceiling height of 10 feet; however, dehumidifier effectiveness in controlling space RH conditions is contingent on how well the controlled space is sealed from the outside. Bug infestation can also be eliminated with a low RH environment. Desiccant and refrigerate based models have power requirements from 220VAC/1Phase, 208- 230/3Phase/50-60Hz to 460VAC/3Phase/50-60Hz with electric or gas regeneration depending on what site utilities are available and what style dehumidifier you choose for your climatic RH and temperature conditions. Normally dehumidifiers in this size range will be offered in desiccant models; however, refrigerate models are available in the lower range of 1,000 to 1500 SCFM.
