Desiccant bags are ideal for keeping the air in control cabinets dry. Silica gel bags as well as bentonite and superadsorber bags are suitable for this purpose.
Silica gel is used when the humidity in the control cabinet needs to be quickly reduced and kept at a very low level. With a capacity of 40% of the dry weight, silica gel ensures strong drying and, in the silica gel orange-green variant, also indicates to you in color when the bag is saturated and should be replaced.
Bentonite bags, on the other hand, are suitable if the humidity is to be lowered over a long period of time. The bags with water-permeable fleece or in the dust-tight variant with MILD absorb significantly more water than silica gel, but have a weaker bond to humidity. A color indicator is not available.
Superadsorber bags are the first choice when liquid water has already collected in the control cabinet. The bags absorb extremely high amounts of liquid water and can be laid out on the floor of a control cabinet, for example. With only 2g granulate weight already 150ml water is absorbed. In combination with silica gel or bentonite bags, the use is particularly effective.
