All N.E.M coils are rewound using very high quality materials and state of the art machinery.
Once the coil has been rewound it is then impregnated with quality resin, then vacuumed down to
-750mmHg to ensure there is no air trapped in the layers. This process also draws the resin into the depths of the coil. The coil is then baked until the resin is completely cured. All our coils are rewound using this procedure, resulting in an air tight / water tight coil.
