Self dehydrating breather type SDB
Main Benefits for End User are:
1. Increase transformer reliability
Consistent moisture absorption ensured by:
- two independent silicagel tanks working alternatively
- continuous monitoring of silicagel saturation.
2. Operational cost savings
Automatic silicagel regeneration process drastically reduce
expensive maintenance activities.
3. Easy to install
Suitable for new installation and retrofit case.
Compatible with with EN and DIN standards.

Moisture is a leading cause of transformer aging.
Avoiding moisture ingress into the transformer is paramount to
avoiding outage and maximizing the lifetime of the equipment.
The traditional way of managing this problem is with
conventional breathers which are expensive to maintain
and present a significant risk of moisture entering into the
transformer between checks. In response to this situation,
COMEM has developed the Self Dehydrating Breather (SDB)
which delivers the best performance of any low maintenance
solution on the market:
COMEM SDB is the only solution to guarantee a consistent flow
of dry air, out-performing both conventional breathers and
alternative low maintenance solutions.
Self Dehydrating Breather SDB family is the right choice in order
to minimize the possible risk of transformer outage due to
insulation fluid impairment through moisture: thanks to its unique
and proven working principle, the air is always fully dehydrated
because silicagel tanks are independent each other thus the
regeneration process does not start simultaneously in the two
tanks.

Model selection
The below number and size of Self Dehydrating Breathers are ‘Rule of Thumb’ recommendations for the devices in question. This is to
be considered as a guide only and should not replace good design and engineering practice and experience

SDB-30 and SDB-15 operating principle
The self-dehydrating air breather works in accordance with the
following principles.
During the normal operation the oil conservator intakes air that
passes through the metallic filter. The metallic filter stops dust,
sand and other particles from the contaminating air. The air then
passes through the salt tank 1.
The salt tank is filled with silica gel that absorbs the moisture.
The dehydrated air goes through piping to the oil conservator.
When the silica gel absorbs the moisture in the air, the weight
of the salt increases and is constantly monitored by a weighing
cell. When the weight increases and exceeds the pre-set value a
solenoid valve blocks the passage of air through salt tank 1 and
deviates through the “plenum chamber ” 2.
At the same time, a heating system inside tank 1 is activated.
The water vapor leaving the silica gel is expelled outward by a
fan that also dissipates the heat.
Inside the salt, a probe controls the temperature of the heating
element.
During the functioning of the device, the weighing cell
temperature is monitored by a temperature sensor mounted in
the upper part.
As soon as the salt regeneration in tank 1 is completed, the
solenoid valve is de-energized and the airflow through tank 2 is
inhibited. The salt in this tank (2) is also dehydrated, regeneration
of the salt in tank 2 follows automatically.
No maintenance is required for replacement and regeneration of
the desiccant.

SDB-10 operating principle
When the silica gel absorbs the moisture in the air, the weight
of the salt increases and is constantly monitored by a weighing
cell. When the weight increases and exceeds the pre-set value a
solenoid valve blocks the passage of air through salt tank 1 and
deviates through the main self-dehydrating breather by the pipe
connected on one of the two plug.

temperature is monitored by a temperature sensor mounted in
