Ge NCUU36BT5S Uncased Evaporator Coil 3 Ton R454B

Product Description

The GENERAL ELECTRIC NCUU36BT5S is a 3-ton uncased evaporator coil designed for upflow applications in B-cabinet air handler configurations. Built for use with R454B refrigerant, this coil is a direct response to the ongoing refrigerant transition away from R-410A. The uncased design allows integration into existing or new air handler cabinets where the coil section is enclosed by the unit itself rather than a factory-installed outer shell. Rated at 3 tons of cooling capacity, it is sized for residential or light commercial systems and is installed by licensed HVAC technicians as part of a split-system air conditioning or heat pump setup.

This coil is intended for upflow B-cabinet installations where the evaporator sits above the furnace or air handler blower section and airflow travels upward through the coil. It is suited for residential split-system cooling and heat pump applications requiring R454B refrigerant compatibility. The uncased form factor is commonly used in new construction and retrofit installations where the installer fits the coil into a factory cabinet or field-fabricated enclosure. Matching the coil to the correct cabinet dimensions and airflow rating is essential for proper system performance.

Key Features

• 3-ton cooling capacity for residential and light commercial split systems
• R454B refrigerant compatible, aligned with current low-GWP refrigerant transition requirements
• Upflow orientation for B-cabinet air handler configurations
• Uncased design for integration into field or factory enclosures
• Weighs 31.35 pounds for manageable single-technician handling during installation

Compatibility

Designed as an OEM-style replacement or new-installation evaporator coil for B-cabinet upflow air handlers and split-system condensing units charged with R454B refrigerant.

Installation Notes

Installation must be performed by a licensed HVAC technician with EPA Section 608 certification for handling regulated refrigerants. Disconnect and lock out all electrical power and close refrigerant service valves before removing or installing the coil. Verify cabinet dimensions and airflow direction match the coil orientation before securing the coil in place. Leak-test all refrigerant connections after installation and confirm proper refrigerant charge per the outdoor unit nameplate before startup.
