Insulating oils for transformers are hygroscopic and strongly attract water molecules. If a transformer “breathes in” air from the environment, water molecules are also carried inside. The insulating oil absorbs these. The use of a dehumidifier has therefore been standard in the field of transformers for years, because it dries the “inhaled” air in advance.
At GIEBEL, we have designed an adsorber especially for use on the transformer, whose maintenance requires only the opening of 3 quick-release fasteners and the replacement of the cartridge. The loaded cartridge can be returned to us for reconditioning (Send & Refresh).
