Adp HE32136A140A000067 Uncased Evaporator Coil 3 Ton

Product Description

The ADP HE32136A140A000067 is a 3-ton uncased evaporator coil designed for residential and light-commercial air conditioning and heat pump systems. Rated at 36000 BTU/h with a 1200 CFM airflow capacity, this coil uses a copper slab construction and a piston metering device sized for R-410A refrigerant. The galvanized steel cabinet is uncased with a right-hand drain orientation. Refrigerant connections are copper for straightforward brazing on both copper and aluminum slab configurations. The coil ships air-pressure tested at 500 psi, helium leak tested, sealed with rubber plugs, and charged with dry nitrogen to protect internal components before installation.

This coil is intended for use in forced-air split systems — air conditioning or heat pump configurations — where a field-installed or factory-installed metering device is required. The piston metering device body is externally accessible, allowing easy piston swap or TXV field conversion without pulling the coil. The drain pan incorporates a Microban antimicrobial additive to resist mold and mildew growth, and dual 3/4-inch FPT condensate drain ports are located on both the front-left and front-right sides of the pan. UV-resistant drain pan material is rated to 450 degrees F. The short cabinet profile and long refrigerant line stubs simplify installation in tight air handler applications.

Key Features

• High-efficiency lanced fin design for improved heat transfer
• Copper slab with copper refrigerant connections sized for easy brazing
• Piston metering device with externally accessible body for field piston change or TXV conversion
• Coil tested at 500 psi air pressure and helium leak tested prior to shipment
• Dual 3/4-inch FPT condensate drains on front-left and front-right of drain pan
• Microban antimicrobial additive in drain pan inhibits mold and mildew growth
• Cabinet air leakage rated at 1 percent or less per Intertek lab testing

Compatibility

Designed for use with R-410A refrigerant in split-system air conditioners and heat pumps. Compatible with R-22 and R-410A systems per manufacturer data. Threaded expansion valves are available factory installed or as a field-installed kit for systems requiring TXV metering.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with local mechanical codes and the system manufacturer guidelines. Shut off all electrical power to the air handler and disconnect refrigerant circuit pressure before beginning coil installation or line set connections. The uncased design requires field integration into the air handler cabinet; verify cabinet dimensions and drain pan orientation before mounting. Refrigerant line connections are copper and intended for brazing — follow accepted industry practices for nitrogen purge during brazing to prevent internal oxidation.
