Inertaire® oil preservation systems

The Inertaire® System provides a regulated nitrogen gas supply to the gas space of power transformers. The user inserts a nitrogen gas cylinder into the Inertaire compartment; makes the necessary gas connections and the Inertaire system will maintain a positive pressure nitrogen gas blanket in the transformer’s gas space. The user can set the pressure range and the Inertaire system will maintain the set pressure range by adding nitrogen or venting over pressure to the atmosphere. The Inertaire system contains alarms to alert the user to over pressures or empty nitrogen bottles.
