The NCHC36AT5S is a 3-ton evaporator coil engineered for compatibility with R-454B refrigerant systems and includes a factory-installed refrigerant detection sensor. Built with durable aluminum alloy tube and fin construction tested through 500 hours of salt spray exposure, this coil delivers reliable performance in demanding climates. Pre-formed flanges align with matching gas furnaces for streamlined installation, while longer service valve connections accommodate both mechanical and brazed methods. An antimicrobial drain pan helps inhibit mold and mildew growth for cleaner indoor air.
