Area of use
The dehydrating breathers are produced for offshore use in marine climates in accordance with ISO-standard ISO 12499-2 and ISO 9223.
Coated in accordance with C5M and tested for 1 500 hours in a climate cabinet. Parts prone to suffer from corrosion and galvanic corrosion are sealed.
The C5M designation means that the dehydrating breathers are especially suited for use in transformers situated on oil rigs, in coastal regions or on offshore wind power plants.

Step by step
1. Screw the dehydrating breather onto the pipe under- neath the expansion tank. The cover has a location flange. With types 4130-4 and 4140 the base also has a location flange.
2. Loosen the three upper wing nuts a few turns and then lower the front retainer bolt. Remove the plexiglass container and fill it with silica gel.
3. Check that both gaskets are correctly located, and fit the container. Tighten the wing nuts firmly, to ensure good sealing.
4. Remove the oil trap bowl by loosening the wing nut on the underneath and turning the retainer forwards 90 degrees. Fill with transformer oil up to the level mark on the oil trap.
5. Make sure the oil does not moisten the silica gel as this will destroy the gel.
