Air Conditioner Range, Efficiency & Performance

Emerald Energy split systems are wall-mounted, reverse-cycle air conditioners, meaning they provide both heating and cooling. The range covers common residential capacities, spanning from 2.5kW to 7.6kW. 

All models use inverter technology, which helps the system run smoothly and use less power, and R32 refrigerant, a newer cooling gas that is more energy-efficient and better for the environment. The models also come equipt with Domain’s ‘Golden Fin anti-corrosion coating’, which adds multiple protective layers to the outdoor unit to help reduce rust and damage from moisture and salty air.

Key features

• Cooling and heating in one reverse-cycle system

• Eco mode and sleep modes

• Quiet operating mode

• Self-cleaning function

• Anti-corrosion coated outdoor unit

• Optional app control via Emerald AC Link
