Bali Airport — Passenger Comfort at Scale

The Venue

Ngurah Rai International Airport is Bali’s main gateway, handling millions of passengers annually. The airport features extensive outdoor and semi-outdoor areas including walkways, waiting zones, taxi queues, and transit corridors where passengers spend significant time exposed to the elements.

The Challenge

Bali’s tropical climate means that outdoor airport zones are consistently hot and humid. Passengers arriving from long flights, families with children, and elderly travelers all face discomfort in these transitional spaces between the aircraft, terminal, and ground transportation.

The scale of the challenge was significant: thousands of passengers move through outdoor zones every day. Traditional air conditioning was either impractical or impossibly expensive for open-air and semi-covered spaces of this size. Fans alone could not deliver meaningful relief from 32-34 degree heat.

The airport needed a solution that could cover large areas efficiently, operate reliably under continuous daily use, and keep maintenance requirements manageable for an infrastructure operation of this scale.

The Solution

MistSystem designed and installed a large-scale high-pressure mist cooling system across multiple outdoor zones at the airport. The installation was one of the most extensive in the MistSystem portfolio, covering outdoor waiting areas, walkways, and transit corridors.

Key elements of the installation:

• 70-bar high-pressure technology producing ultra-fine mist that cools the air without wetting passengers, luggage, or surfaces
• 6mm stainless steel lines built for durability and continuous operation in a high-traffic environment
• Multiple zones covering different outdoor areas, each capable of independent operation
• Industrial-grade reliability designed for all-day, every-day operation without interruption

The system was engineered to handle the demands of a public infrastructure facility where downtime is not an option and the user base ranges from international tourists to local commuters.

The Result

The mist cooling installation transformed the passenger experience in outdoor airport zones, delivering temperature reductions of up to 10 degrees Celsius in treated areas.

Passenger comfort: Travelers waiting for taxis, walking between terminals, or queuing in outdoor areas now experience noticeably cooler conditions. The difference is immediately felt when entering a mist-cooled zone.

Operational efficiency: The system uses up to 90% less energy than air conditioning would require for equivalent coverage. For an operation running continuously with massive square footage, this translates into substantial energy savings.

Reliability: The stainless steel construction and high-pressure pump systems are designed for the demands of a public facility. MistSystem provides maintenance support to ensure consistent operation.

Scale proof: The airport installation demonstrates that high-pressure mist cooling works not just for boutique hospitality venues but for large-scale public infrastructure where thousands of people need comfort daily.
