Figure 5-6. Hutment Framework (Width over 20 Feet)

(l) Dehumidification system. The dehumidification system shall include the proper size dehumidification

unit, humidistat control, hygrothermograph, duct work, and line connections. It shall conform to MIL-D-28594.

(m) Duct work. After the dehumidification equipment has been installed, the contractor shall furnish and

install all necessary galvanized sheet metal ducts. Ducts shall also be located so as not to short circuit dehumidified air

with return air or interfere with moving equipment inside the hutment. The duct work shall be appropriately sealed so that

all joints where leakage may occur is eliminated.

b. Indoor metal hutments.

(1) This type of structure serves the same purpose as indoor plastic film dehumidified structures. However,

they are more expensive and are subject to more air changes per day (fig 5-3).

(2) These structures are made from lightweight galvanized sheets fabricated to structural members. However,

some are corrugated quonset-type and are self-supporting. There are a number of private companies including some of

the steel manufacturing companies that sell indoor-type metal hutments. Each manufacturer has his/her own particular

design.
