OXBOX BY TRANE TXV KIT, COIL AND AIR HANDLER, 5.0 TON R-454B – 5AYTXVH3A6000A

Description

• A listing shows an accessory kit: ADP TXV Kit – R‑454B 3.5‑5 Ton (Part No. 167757902A) for coil/air handler applications.

  • This covers the tonnage range up to 5 Ton, which might overlap with “5.0 Ton” systems.

  • It explicitly states “Refrigerant Type – R‑454B”.

• A 5‑Ton evaporator coil with factory‑installed TXV for R‑454B is listed: “5 Ton … Multi‑Positional With TXV … R454B”

  • So while it includes TXV, it’s a coil with TXV included rather than a separate kit for coil + air handler.
