Dehydrating Breathers

Keep the moisture away from your transformers

Moisture is a leading cause of transformer aging. Avoiding its ingress into the insulation is paramount to avoiding unplanned outages and maximizing equipment lifetime. Hitachi Energy Dehydrating Breathers are designed to absorb moisture from the intake of air into the transformer during the thermal contraction of the oil.
