1.5 Ton / 18,000 BTU Capacity

The EcoStar Duke 18DU02 belongs to the 1.5 Ton / 18,000 BTU category.

Its variable inverter cooling specifications are approximately:

• Maximum Cooling Capacity: 19,448 BTU/h
• Average Rated Cooling Capacity: 17,401 BTU/h
• Minimum Cooling Capacity: 4,436 BTU/h

The variable output allows the inverter system to increase cooling when demand is high and reduce output after comfortable indoor conditions are reached.

Heating Capacity

The AC also provides inverter heating for winter use.

Its current rated heating range is approximately:

• Maximum Heating Capacity: 18,766 BTU/h
• Average Rated Heating Capacity: 17,742 BTU/h
• Minimum Heating Capacity: 4,436 BTU/h

This allows the AC to provide year-round climate control.

Heat & Cool Operation

The EcoStar 18DU02 provides Heat & Cool functionality.

It can provide cooling during hot summer weather and heating during colder conditions from the same split air-conditioning system.

Inverter Technology

The inverter system automatically adjusts compressor output according to room requirements.

Instead of continuously operating at maximum power, it can increase or reduce performance according to actual cooling or heating demand.

This helps provide:

• Stable room temperature
• Reduced temperature fluctuations
• Smooth operation
• Controlled electricity consumption
• Efficient cooling and heating

Actual electricity consumption depends on room heat load, thermostat settings, outdoor conditions, insulation, and installation quality.

R32 Refrigerant

The EcoStar 18DU02 uses R32 refrigerant.

R32 is widely used in modern inverter air conditioners and provides effective heat-transfer performance while having a lower Global Warming Potential than R410A.

Real 4-Star Energy Rating

Current Premium-series Pakistani listings market the 18DU02 WC Premium as a Real 4-Star Product.

The inverter system and adjustable power control are designed to support energy-conscious operation.

Actual electricity savings vary according to room conditions and usage.

5-Step Power Control

The 5-Step Power Limit Remote provides five selectable operating-power levels.

This allows users to manage the maximum AC power demand according to their cooling requirements and available electrical capacity.

It can be useful for:

• Managing household electrical load
• Reducing maximum AC demand
• Energy-conscious operation
• Solar-powered operation
• Situations where maximum cooling output is unnecessary

Low Voltage Operation – 150V to 270V

The EcoStar 18DU02 is designed to operate across approximately 150–270V.

This wide voltage range provides additional flexibility where electricity supply fluctuates.

Suitable electrical protection is still recommended where voltage conditions are severe.

65Hz Quick Cooling & Heating

The Duke Series uses a 65Hz startup strategy for faster cooling and heating after startup.

This allows the compressor to increase its operating performance quickly when rapid room-temperature adjustment is required.

It is particularly useful when entering a hot room or when faster winter heating is needed.

4D Airflow

The 4D Airflow System distributes conditioned air in multiple directions.

It helps provide:

• Wider room coverage
• Better cooling distribution
• Improved heating circulation
• More uniform indoor temperatures
• Reduced concentrated airflow

Strong Double Intake Air Door

Current WC Premium listings also specify a Strong Double Intake Air Door.

The improved intake design helps the indoor unit draw room air effectively before cooling or heating it and returning conditioned air into the room.

Self-Cleaning Evaporator

The Self-Cleaning Evaporator helps reduce moisture and buildup inside the indoor unit.

It supports:

• Cleaner internal surfaces
• Reduced dust accumulation
• Better airflow
• Easier routine maintenance
• Reliable long-term performance

Regular filter cleaning and professional servicing are still recommended.

Gold Fin Evaporator & Condenser

Both the evaporator and condenser feature Gold Fin protection.

This coating helps improve resistance against moisture and corrosion.

Benefits include:

• Better heat-exchanger durability
• Improved corrosion protection
• Reliable long-term performance
• Protection against environmental exposure

Environmental Protection Coating – EPC

The Environmental Protection Coating (EPC) provides an additional protective layer to important AC components.

It is designed to improve durability in demanding environments involving dust and moisture.

Labyrinth Design PCB Protection

The Labyrinth PCB and outdoor-unit protection design helps protect sensitive electronic components from:

• Dust
• Moisture
• Rain exposure
• Short-circuit risks

This provides additional protection for the inverter electronics.

Wi-Fi Ready

The EcoStar Duke 18DU02 is Wi-Fi Ready with USB connectivity.

Compatible smart-control functionality can allow convenient AC operation through a smartphone.

Depending on the supplied package, a compatible Wi-Fi USB accessory may be required.

AI Temperature Control

The AC includes Precise AI Temperature Control with sensing accuracy up to approximately 0.1°C.

Fine temperature sensing helps the inverter system make smoother adjustments and maintain more consistent indoor comfort.

Multi-Health Filters

The Multi-Health Filter system helps capture dust and selected airborne impurities from circulated room air.

Regular filter cleaning is important for maintaining airflow and filtration performance.

Low-Refrigerant Self-Diagnosis

The AC includes Self-Diagnosis for Low Refrigerant.

This function can help identify operating conditions that may indicate insufficient refrigerant.

Any refrigerant problem should be inspected by a qualified AC technician.

Solar Compatible

The EcoStar Duke 18DU02 is officially listed as Solar Compatible.

Actual solar operation depends on:

• Solar inverter capacity
• Available PV output
• Battery or grid configuration
• Other connected appliances
• Electrical installation

A correctly designed solar system should be used.

Large LCD Remote

The AC features a Large LCD Remote Control for convenient viewing and operation.

The remote also incorporates the 5-Step Power Control system.

IPX5 Water-Resistant Remote

The Duke Series remote is listed with IPX5 water-resistance protection.

This provides additional protection against water exposure under applicable test conditions, but the remote should not be submerged.

Low Standby Consumption

Current WC Premium listings specify approximately 0.3W standby power consumption.

This helps reduce unnecessary electricity consumption while the AC remains powered but is not actively cooling or heating.

Cooling Power Consumption

Official Duke 1.5 Ton specifications list:

• Maximum Cooling Input: 2,100W
• Average Cooling Input: 1,660W
• Minimum Cooling Input: 290W

The wide range reflects variable inverter operation.

Heating Power Consumption

Heating input is approximately:

• Maximum Heating Input: 1,800W
• Average Heating Input: 1,530W
• Minimum Heating Input: 250W

Actual electricity use varies according to room conditions and system demand.

Premium White Finish

The WC Premium variant features a clean White finish suitable for:

• Master bedrooms
• Living rooms
• Family lounges
• Offices
• Drawing rooms
• Modern interiors
