2ND GENERATION
Auto-Charging Dehydrating Breathers
INTELLIGENT TECHNOLOGY HELPS KEEP OIL DRY AND TRANSFORMERS FREE FROM CONTAMINANTS
Second generation ARDBs use breather
intelligence technology and a bypass valve to
automatically schedule regeneration and isolate
the transformer from the silica gel. Modular
design and high temperature, UV-resistant,
anti-corrosive plastic housing allow for use in
confined areas.

AUTOMATIC RECHARGE USING INTELLIGENT
REGENERATION CONTROL TECHNOLOGY
Keeping the silica gel dry eliminates the need for periodic replacement
of the desiccant. Logic controls include a humidity switch, timer and
vacuum protection circuit that automatically “learn” to regenerate during
transformer exhale only, driving moisture out of the desiccant while
keeping the transformer isolated from steam-generated contaminants.
USER-CONTROLLED TIME-BASED SET TINGS
Included timer allows variable time-based settings for user-controlled
regeneration of silica gel. Time settings for 5, 10, 20 or 40 day intervals
can be set by the customer. Intelligent humidity sensor serves as a
back-up to ensure user-based settings are adequate for proper
breather operation.

INTEGRATED AL ARMS
LED indicators on front cover of control box visually alert user of breather
operational status. Relay contacts are also included for remote (SCADA)
breather monitoring.

OPERATION
( D I A G R A M AT L E F T )
During regeneration, a heating element located inside the ARDB2
assembly heats the partially saturated silica gel, driving moisture out.
This moisture condenses on the polycarbonate tube, forming free water,
which then flows down the tube and out the bottom vent.
