El calefactor de ventilador evita la formación de condensación y proporciona una temperatura del aire interior distribuida uniformemente en armarios con componentes eléctricos/electrónicos. El calentador se conecta mediante los conectores de terminales internos. El pequeño tamaño del NTL 411-S lo hace ideal para su uso en recintos donde el espacio es escaso.
