The NCDC24AT5S is a 2-ton evaporator coil engineered for reliable performance with R-454B refrigerant and a factory-installed refrigerant detection system sensor. Featuring durable aluminum alloy tube and fin construction tested through 500 hours of salt spray exposure, this coil is built to withstand extreme climate conditions. Pre-formed flanges align seamlessly with matching gas furnaces for easier installation, while longer service valve connections accommodate both mechanical and brazed options. An antimicrobial drain pan helps resist mold and mildew growth for improved air quality.
