The AUX 1.5 Ton Concealed Duct Type Inverter Air Conditioner (Model: ALTLD-C18/NDR3QA) is a premium, hidden climate control solution built specifically for light commercial spaces and luxury residential apartments.

Ultra-Slim, Concealed Profile

• With an incredibly flat indoor casing height (ranging between 198 mm and 245 mm depending on custom plenum attachments), it is optimized for tight, low-clearance false ceilings. It hides away to preserve wall aesthetics while delivering silent, indirect airflow.

Eco-Friendly & High-Efficiency R32 Refrigerant

•  This unit uses advanced R32 gas. Compared to older R410A systems, R32 is much more efficient, possesses a significantly lower Global Warming Potential (GWP), and carries a higher volumetric cooling capacity—allowing for faster thermal drop times.

Adjustable External Static Pressure (ESP)

• Supports static pressure adjustments up to 160Pa, with a standard operating ESP of 25Pa. This high-pressure capacity allows the internal blower fan to push air through long, complex networks of ventilation ductwork seamlessly, ensuring even distant areas get cooled properly.

Built-in Condensate Drain Pump:

• Comes integrated with an internal drainage pump capable of lifting condensation water up to 70 cm vertically from the drain pan. This completely eliminates common gravity-drain installation constraints and prevents ceiling water leakage.

High-Ambient T3 Climate Engineering

• The inverter rotary compressor inside the outdoor unit (Model: ALT-C18/NDR3A) is built for harsh tropical conditions. It runs stably without thermal cutting or overloading even during intense summer heat waves where ambient outdoor building metrics cross 52°C.

Automatic Airflow Volume Adjustment

• The smart fan motor monitors resistance within the ventilation system and automatically self-adjusts its RPM velocity to match the layout of your ducting network, maintaining a uniform, draft-free air volume across the space.

PCB Refrigerant Cooling System

•  Uses a cooling mechanism to regulate the control board, significantly improving overall reliability and durability.
