The TB-DV 3M is a dehumidifier / ventilation dryer especially designed for transformers. The adsorber has a disposable cartridge (Recyclable in Send & Refresh System), valves and FKM seals. It is suitable for indoor & outdoor use. With a capacity of 1,00kg of GIEBEL Xdry®, it adsorbs up to 350ml of water until the color of the desiccant changes. Thanks to a 2μm filter, the sucked in air is also completely cleaned and an activated carbon layer adsorbs oil mist to protect the desiccant and the environment from contamination.
