Key Features

Twin Rotary compressor (more efficient and smoother than a single rotary compressor)

Designed for concealed duct installations

Adjustable external static pressure up to 120 Pa

Supports long refrigerant pipe runs (up to 50 m)

R410A refrigerant

Wired controller operation

Built for commercial and large residential applications.


Power Consumption in Practice

At full cooling load:

Draws approximately 2.8–3.0 kW

10 hours/day ≈ 28–30 kWh/day

Significantly higher electricity consumption than a modern inverter system because the compressor runs at fixed speed.


Room/Building Size

A 3-ton ducted system is typically suitable for:

100–150 m² of well-insulated space

Large offices

Retail shops

Churches

Open-plan homes or halls


Actual coverage depends on ceiling height, occupancy, windows, and insulation.

Bottom line: The AUW-36CT4ST is a heavy-duty 3-ton non-inverter ducted outdoor unit with a twin rotary compressor, 34,090 BTU cooling capacity, and an 83 kg outdoor chassis designed for medium-to-large commercial installations.
