Hisense ADT-12UX3SBL Ducted Indoor Unit 12000 Btu/h

Product Description

The HISENSE ADT-12UX3SBL is a ducted type indoor unit rated at 12000 BTU/h, designed for use in ducted mini-split or multi-zone HVAC systems. This unit mounts within the duct system and delivers conditioned air through existing or new ductwork, making it well suited for applications where a concealed installation is required. Licensed HVAC technicians install this unit as part of a complete split system, pairing it with a compatible outdoor condensing unit. It is built to deliver quiet, distributed airflow without an exposed wall-mounted or ceiling-mounted cassette appearance.

This ducted indoor unit is appropriate for residential and light commercial applications where a hidden air handler is preferred. Typical installations include homes, offices, or multi-room setups where maintaining interior aesthetics is a priority. The unit integrates into a ducted distribution system, allowing conditioned air to reach multiple zones or rooms from a single concealed location. Installers working with multi-zone systems should verify outdoor unit compatibility and total system capacity before installation.
