with a double tank present in the entire product range as a stand-alone solution for increased performance and safety.
The new type of eSDB has a robust and compact design with no external wires.
We have implemented a double tank and condition-based technology in the entire product range to increase performance and safety and guarantee the uninterrupted continuous moisture absorption.
The new self-dehydrating breather eSDB has two tanks filled with special silica gel. A load cell is continuously monitoring silica gel weight increase. When the first tank is saturated, a smart solenoid valve deviates the passage of the air to the secondary tank.
When air breathed by the conservator goes through the tank A any moisture is absorbed by special silica gel.
The moisture in the outer air increases the weight of the gel.
When the variation of weight exceeds the set threshold value a smart solenoid valve blocks the passage of air through the saturated tank A and deviates the air flow through tank B.
Simultaneously a heating system inside tank A is activated for regeneration of silica gel salts.
Silica gel regeneration is happening only when needed.
One breather for the oil circuit of the on-load tap-changer, and a second breather for the transformer tank.
The new compact design of the self-dehydrating breather eSDB enables easy installation.
The new user-friendly interface allows full control over the threshold set-up and functionality check on-site.
We aim to be part of an increasing circular economy.
Our packaging material is almost 100% recyclable. By choosing our new self-dehydrating breather type eSDB, you do not need to worry about silica gel replacement and disposal.
