Adiabatic Cooling with ORBIT WING®
Maximum cooling capacity with minimal energy consumption
Energy costs, sustainability, and strict environmental goals are placing ever-higher demands on ventilation and cooling in most buildings. Many hospitals, schools, office buildings, hotels, and industrial facilities already have a good ventilation system but lack an energy-efficient cooling solution.
ORBIT WING® from Merlin Technology, supplied by Klimabefuktning AS, is one of the market’s most advanced solutions for adiabatic cooling. The system utilizes the natural evaporation of water to deliver high cooling capacity with very low energy consumption—without compressors or traditional refrigeration.
What is adiabatic cooling?
Adiabatic cooling (also known as evaporative cooling) works by allowing microfine water droplets to evaporate in the airflow. As the water changes from a liquid to a vapor, it absorbs heat from the air, causing the temperature to drop naturally.
ORBIT WING® takes this principle to a new level through patented wings, high-pressure nozzles, and intelligent control. The result is a cooling solution that is perfectly suited for Norwegian conditions—both as a primary cooling system and as a supplement to existing systems.

Patented blades – the core of the technology
What sets ORBIT WING® apart from other adiabatic systems are its patented wings. When the water leaves Merlin’s Micro Drop high-pressure nozzles, the extremely fine droplets are guided along the wings and set into a controlled rotation.
This offers three key benefits:
The combination of Micro Drop nozzles, patented fins, and intelligent pressure control provides up to 98% evaporation efficiency. This means that nearly all of the water contributes to cooling—it is not lost as excess water.
Lower costs than traditional cooling
Many companies focus solely on the initial investment cost. With ORBIT WING®, it’s the total operating costs that really stand out. Starting in the first year, you’ll see significant savings on maintenance and energy consumption, and the total investment will pay for itself within 3–5 years.
The system reduces life-cycle costs by:
In buildings that already have mechanical cooling, ORBIT WING® significantly reduces the load on the chillers, resulting in lower electricity consumption and a longer service life for the existing system.
Integrated Water Treatment with Reverse Osmosis
Water quality is critical for performance, hygiene, and maintenance. ORBIT WING® therefore comes equipped with an integrated reverse osmosis (RO) water treatment system that removes up to 99% of salts, minerals, and impurities.
This offers several important benefits:

Who is ORBIT WING® designed for?
The system can be used in most small and large spaces that require efficient cooling, but is particularly well suited for:
In many European buildings, ORBIT WING® can serve as a complete cooling solution. In other buildings, it serves as a highly effective supplement that reduces the need for traditional mechanical cooling.

Sustainability That Pays Off
A modern, sustainable building isn’t just about reducing energy consumption. It’s about using fewer resources throughout its entire lifecycle. ORBIT WING® was developed with exactly this in mind—maximum performance with minimal resource consumption.
Lower energy costs, reduced water consumption, a longer service life for technical systems, and lower CO₂ emissions make the system a smart economic choice—both for environmental performance and for the bottom line.
