Upgrade to greener cooling.

State-of-the-art AC Units built for efficiency, flexibility and control.

Our high-performance AC units combine inverter technology, zone-level control, and BMS integration — delivering intelligent cooling for modern UAE buildings.

AC technology that pays off.

Optimize energy use with inverter-driven performance

Enhance indoor comfort with precise temperature regulation

Be energy efficient and cut costs

Smarter cooling for every building.

From apartment towers to executive offices and busy retail spaces, cooling needs can vary considerably — and our energy-efficient split air conditioning units are designed to meet those needs. 

Equipped with modern inverter technology, they provide faster cooling, quieter operation and reduced energy consumption, all while lowering electricity bills. These systems maintain a consistent indoor climate year-round, providing performance, style and control in one sleek solution, whether it’s the height of summer or a cooler evening.

The tech behind the comfort.

Each split AC unit functions as a compact, self-contained system — ideal for targeted, zoned cooling. Indoor units are mounted discreetly on walls or ceilings and connected to outdoor condensers via slim refrigerant lines. Inverter compressors adapt dynamically to room conditions, ensuring powerful cooling at start-up and efficient operation as temperatures stabilize. The result: Optimal comfort with minimal noise and energy use — all without the complexity of chilled water systems or central pumping.

Lower energy use without sacrificing comfort

Advanced inverters and zone control boost cooling efficiency, cut energy use, and keep indoor climates consistent.

Seamless integration with smart building systems

BMS-compatible units enable control, predictive maintenance, and real-time optimization to boost performance and efficiency.

Designed for UAE standards and sustainability goals

AC units meet local codes and Net Zero 2050 goals, delivering top performance while helping you manage greener buildings.
