Adp hg51a60a200a0004n Uncased A-coil 20in Lh R-454B Txv

Product Description

The ADVANCED DISTRIBUTOR PRODUCTS hg51a60a200a0004n is an uncased A-coil designed for split-system air conditioning and heat pump applications. It features left-hand refrigerant connections and comes factory-equipped with a thermostatic expansion valve (TXV) metered for R-454B refrigerant. At 20 inches wide, this coil fits a range of air handler and furnace configurations. The multi-position design allows installation in upflow, downflow, or horizontal orientations, giving HVAC technicians flexibility when working within tight mechanical room layouts or attic installations.

This coil is suited for residential and light commercial split-system cooling installations where R-454B refrigerant is specified. The factory-installed TXV meters refrigerant flow precisely, making it a reliable match for systems in the 3.5 to 5 ton range. It is noted as compatible with Allied 3.5 to 5 ton 7AC units. Left-hand connections orient toward the left side of the coil when viewed from the front, which determines line set routing in the installation space.
