Friedrich TCFY4821STANMC Cased Evaporator Coil 48000 Btu/h

Product Description

The FRIEDRICH TCFY4821STANMC is a cased evaporator coil rated at 48000 BTU/h, designed for use with R454B refrigerant in central split-system air conditioning and heat pump applications. At 3.5 to 4 nominal tons, it serves residential and light commercial systems requiring a reliable indoor heat-exchange component. The coil ships with a factory-installed thermostatic expansion valve (TXV), providing accurate refrigerant metering across a range of operating conditions. The cased design protects the coil assembly and simplifies installation by integrating directly into the air handler or furnace cabinet. Licensed HVAC technicians install and commission this component.

This evaporator coil is suited for multi-position installations, meaning it can be configured for upflow, downflow, or horizontal airflow depending on the equipment layout. At 21 inches wide, it fits air handlers and furnace platforms built to accept that cabinet width. The R454B refrigerant compatibility positions this coil for use in newer systems designed to meet current low-GWP refrigerant standards. It is intended for split-system pairings where the outdoor condensing unit and indoor coil are matched to R454B charge requirements.

Key Features

• 48000 BTU/h capacity covering 3.5 to 4 nominal tons
• Factory-installed TXV for precise refrigerant metering
• Compatible with R454B low-GWP refrigerant
• Multi-position orientation supports upflow, downflow, and horizontal configurations
• Cased construction for clean, protected installation into air handler or furnace cabinets
• 21-inch cabinet width fits standard platform air handler openings

Compatibility

Designed as an OEM-style cased evaporator coil replacement or new-installation component for R454B multi-position split-system applications in the 3.5 to 4 ton capacity range with a 21-inch cabinet width.

Installation Notes

Installation must be performed by a licensed HVAC technician certified to handle refrigerants under EPA Section 608 regulations. Disconnect and lock out all electrical power to the air handler or furnace before opening the cabinet and positioning the coil. Ensure the refrigerant line connections are leak-tested and the system is properly evacuated before charging with R454B. Follow the equipment manufacturer's specifications and local mechanical codes for drain pan, condensate line, and duct connections.
