The Hisense 3 Ton Concealed Duct Type Inverter Air Conditioner (Indoor Model: AUD-36CX4SHH / Outdoor Model: AUW-36CT4ST) is a premium, high-capacity central cooling system designed to be completely integrated out of sight within standard false ceilings or drop plenums. Engineered to provide heavy-duty temperature control across expansive residential layouts (villas, large open-plan apartments) and light commercial properties, this system pairs variable-speed Twin-Rotary inverter technology with a slim, space-saving layout.

Advanced Twin-Rotary Inverter Efficiency

•  Driven by a variable-frequency Twin-Rotary compressor. By modulating motor speeds smoothly instead of using power-spiking on/off cycles, it delivers precise temperature stability, minimized vibration, and significant energy savings under continuous use.

Hi-Smart High-Ambient Protection

•  Explicitly tropicalized with advanced adaptive tech and high-stability PCBs. The thermodynamic loop guarantees stable cooling output in extreme high-ambient desert environments  and can maintain mechanical function in survival thresholds reaching.

Flexible 2-Way Air Intake Alignment

•  Offers structural adaptation for tight mechanical areas. The return air plenum can be easily repositioned to intake air from either the back or the bottom of the handler depending on the architectural framing of the ceiling.

Built-in Drain Pan & High-Lift Water Pump

•  Comes factory-equipped with an integrated condensation drain pan alongside a built-in safety water level switch and condensate lift pump. This setup simplifies plumbing layouts in shallow ceilings and prevents stagnant water backing up into structural drywall.

Seven-Fold Rust-Proof Outer Armor

•  The outdoor condenser casing is constructed from hot-dip galvanized steel plate treated with a ceramic baking varnish. This multi-layered defense creates a highly durable shell that completely isolates internal steel from coastal salt-air pitting, humidity rust, and sand abrasion.

Hydrophilic Golden Fin & Anti-Bacterial Coats

•  The heat exchanger fins feature a premium anti-corrosive Golden Fin layer (tested to survive 1,500 hours of aggressive salt spray), preventing corrosion while accelerating condensation run-off. It is supplemented with silver ion anti-bacterial coatings to inhibit mold and bacterial growth inside the air stream.

Eco-Friendly Refrigerant

•  Uses R410A, an efficient refrigerant known for zero ozone depletion and high cooling efficiency.
