Closed circuit cooling towers of the latest generation, forced draft counterflow execution. Fiberglass reinforced polyester casing, EC axial fans as standard and ultra-compact coil with a minimum refrigerant charge. The NTC series closed circuit cooling towers are ahead of their time. They are forced draft counter current cooling towers with fiberglass reinforced polyester (GRP) casing, characteristics that ensure enormous resistance to corrosion and the highest performance. NTC cooling towers incorporate electric motors with innovative EC technology (integrated controller) and feature a very low sound pressure level and therefore very quiet operation. EC motors have superior efficiency, exceeding IE4 requirements. The integrated electronics of the EC motors allows variable speed control of the fan for maximum energy savings of the installation, with reduced power consumption compared to AC motors with VFD. NTC towers are currently the most energy efficient equipment available on the market, exceeding the ErP 2023 standard. Fans with direct drive motors eliminate possible mechanical failures of belt driven motors. The batteries of the NTC towers are hot-dip galvanized in discontinuous process according to UNE.EN ISO 1461:2010 standard. The air inlet is on one side only, which allows its modular implementation, optimizing the necessary floor space and the location of the silent side towards noise-sensitive areas. The fans are installed in the dry air suction section, which prevents condensation and eliminates corrosion problems and premature mechanical failures.
