|Generator “windings” coolers with optional DOUBLE WALL LEAKAGE DETECTION|
|It is essential that water never leaks into the motor windings of an generator cooler.
We use a double tube wall solution in many of our generator coolers – or motor coolers and stator air coolers as they also are called. If there is a problem, water leaks to a special pathway between outer and inner tubes and then to a void at the tube plates. After that, water leaks to the outside, thus warning the chief engineer there is a problem whilst not endangering the windings. This is the reason for the common name “leak detector tubes”.
