General Electric nchc48bt4 4-ton Cased Evaporator Coil

Product Description

The GENERAL ELECTRIC nchc48bt4 is a 4-ton cased evaporator coil designed for horizontal installation in residential and light commercial HVAC systems. This cased coil sits in the air handler or furnace cabinet on the supply-air side, absorbing heat from return air as refrigerant evaporates inside the coil assembly. The B-cabinet configuration fits a specific range of air handler and furnace cabinet widths, making proper cabinet sizing essential before ordering. Licensed HVAC technicians handle installation as part of a split-system or package cooling installation, typically when replacing a failed coil or upgrading system capacity.

The nchc48bt4 is rated for 4-ton (48,000 BTU/h) cooling capacity and is configured for horizontal airflow, making it suited for attic installations, crawlspace systems, and side-discharge air handlers where vertical upflow or downflow orientation is not practical. The cased design means the coil ships in a factory-fabricated cabinet, simplifying installation and reducing the need for field-fabricated coil enclosures. This coil is intended for use in forced-air split cooling or heat pump systems.

Key Features

• 4-ton (48,000 BTU/h) rated cooling capacity
• Horizontal airflow orientation for attic, closet, and side-discharge applications
• Cased design with factory-fabricated cabinet for simplified field installation
• B-cabinet width configuration for compatibility with corresponding air handler and furnace cabinet sizes
• GE manufacture for use in residential and light commercial split-system and heat pump applications

Compatibility

Designed as an OEM-style cased evaporator coil for horizontal split-system and heat pump installations requiring a 4-ton B-cabinet configuration. Verify cabinet width, refrigerant type, and system tonnage match before installation.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with local mechanical codes and the system manufacturer guidelines. Disconnect and lock out all electrical power and recover any system refrigerant before removing an existing coil. Verify drain pan orientation, condensate drain routing, and refrigerant line connections are correct for horizontal installation. Do not braze refrigerant connections without appropriate nitrogen purge procedures to prevent internal oxidation of the coil.
