Evolution Series

Energy Star 21 SEER Ductless Mini Split Air Conditioner Heat Pump System

Evolution Series Energy Star Certified DuctlessAire Mini Split Air Conditioner with variable-speed DC inverter compressor provides a highly efficient, quiet, low-cost professional solution for your cooling and heating needs without requiring any duct work. This energy-efficient system is the ideal solution for open-room applications, such as classrooms, sunrooms, open floor plan flexible-use spaces, man caves, home theaters, offices, studios, bedrooms, bonus rooms over the garage and even basements and garages where heating and cooling is desired. Where there is an open interior space need for heating and cooling, DuctlessAire Mini Splits have the answer. This sleek-looking unit is mounted on the wall, working in concert with an exterior condenser requiring only a small hole to run the lines from the air handler to the condenser. The fans deliver continuous airflow and circulation with year-round temperature comfort and are easily adjusted with a remote control that comes standard with each unit. Because the air handler is mounted above eye level, it is aesthetically attractive, blends well and does little to impede with furniture and decor placement. DuctlessAire Mini Splits are a cost-effective alternative to central HVAC systems and can be installed in just a few hours.

Outstanding Features

3D DC Inverter Technology

With brushless DC motors, 3D DC Inverter air conditioner gains higher efficiency and makes quieter operation which helps to save energy and enhance comfort to consumer: DC Motor of Cross flow fan, DC Motor of Compressor, DC Motor of Axial Flow Fan

Two Direction Air Vane Technology

In cooling mode the air vane opens counter clockwise to direct the air horizontally, allowing for an even cooling effect, in heating mode the air vane opens clockwise directing the air downwards, this time for an even heating effect

Built-in Electronic Protection

Monitoring some abnormal operations or parts failures, microcomputer of the air conditioner will switch off and protect the system automatically; meanwhile, the error or protection code will be displayed on the indoor unit

Dual Sensor Fixes or Remote

By switching to remote sensor and keeping the remote close to you, you tell the air conditioner to set the temperature from wherever the remote happens to be, this counteracts the tendency for the air conditioner to stop cooling or heating because the air around the unit has reached its set temperature (switches off after period of inactivity to preserve battery life)

Healthy Air

Each system includes two high density washable filters and a HEPA filter. Compared with ordinary dust filters, DuctlessAire high density filters reduces dust more than 50% and pollen up to 80%. HEPA filter is a mechanical air filter; it works by forcing air through a fine mesh that traps harmful particles such as pollen, pet dander, dust mites, and tobacco smoke.

Anti-Corrosive Golden Coils

Electroplated hydrophobic coils improve the heating efficiency by accelerating the defrosting process, the unique golden anti-corrosive coating on the coils also aids in withstanding the effects of salty air, rain and other corrosive elements by allowing contaminated water on the coil to run off more quickly reducing the corrosive effect to the coil, heat exchange performance is much longer lasting

Low Ambient Operation

A special built-in low ambient kit can be used in temperatures as low as 5°F for cooling operation, useful for users who need to maintain cooling during winter

Refrigerant Leak Detection

With this new technology the system will alarm when a refrigerant leak is detected by displaying error code

Outdoor Pan Heater

A heating belt is fitted on the base plate of the outdoor unit to avoid accumulation of rain, snow or water on the base plate

Sleep Mode

In sleep mode, the unit automatically decreases the heating or increases the cooling by 1° per hour for the first 2 hours of use, then holds the temperature steady for 5 hours before ceasing operation

Low Noise Airflow

Without decreasing the airflow volume and capacity output, large diameter cross flow fan can bring down the indoor unit noise level by lowering the fan speed

Anti Cold Draft

If the unit is turn on in heat mode when the ambient temperature is low it will warm up prior to fan operation to prevent cold air in heating mode to make people feel more comfortable

Self Cleaning

By pressing clean on the remote control automatically cleans the evaporator to aid in reducing build-up of bacteria and keep the air fresh

Louver Position Memory

The set louver position is stored in memory by the microcomputer, and the louver returns to the stored position when the next operation is performed

Turbo Mode

This function enables the unit to reach the preset temperature in the shortest time
