Southwark Metal 4r816342048 Insulated Coil Plenum R8

Product Description

The SOUTHWARK METAL 4r816342048 is an insulated furnace coil plenum designed to house and enclose an evaporator coil in a forced-air HVAC system. Built to R8 insulation specification, this plenum limits heat transfer between the supply air stream and the surrounding mechanical space, improving overall system efficiency. Measuring 16.75 inches wide by 20 inches deep by 48 inches tall, it fits standard residential and light commercial air handler and furnace coil configurations. HVAC sheet metal contractors and mechanical installers work with this component during new construction and equipment replacement projects.

This coil plenum is used in upflow and downflow forced-air heating and cooling systems where an evaporator coil is installed downstream of the furnace heat exchanger. The R8 insulation value makes it appropriate for installations in unconditioned spaces such as attics, garages, and utility rooms where ambient temperature variation could otherwise affect system performance. The 48-inch height accommodates larger coil assemblies common in mid- to high-capacity residential and light commercial applications.

Key Features

• R8 insulation rating reduces heat gain and condensation risk in unconditioned install locations
• 16.75 inches x 20 inches x 48 inches construction fits standard residential and light commercial coil configurations
• Insulated plenum body limits energy loss between the coil cabinet and surrounding mechanical space
• Sold as a single unit, ready for field installation and sheet metal connection

Compatibility

Designed as an OEM-style insulated coil plenum for use with forced-air furnace and air handler systems requiring a 16.75-inch by 20-inch by 48-inch plenum enclosure with R8 insulation.

Installation Notes

Installation of this coil plenum should be performed by a licensed HVAC technician or sheet metal contractor in accordance with local mechanical codes and manufacturer guidelines. Disconnect power to the air handler or furnace and shut off refrigerant service valves before opening the coil cabinet or connecting the plenum. Sheet metal screws and approved HVAC foil tape or mastic sealant are typically used to secure and seal plenum connections. Verify that plenum dimensions match the coil cabinet outlet before final installation.
