Existing technologies are not the solution to improving thermal comfort in the ever-warming climates because they are energy intensive, unsustainable, impractical and have limited cooling impact

MISTING SYSTEMS AIR CONDITIONING EVAPORATIVE COOLERS

  • Condenses instead of cooling
  • Limited tangible cooling
  • High maintenance
  • Not tenable for outdoor spaces
  • Creates heavy waste heat load
  • Adds to urban heat effect in the city
  • Limited tangible cooling
  • Impractical maintenance in humid

conditions

  • Poor efficiency material, leading to a

bulky footprint

Utilizes patented cooling technology to achieve:

  • Achieving unprecedented outdoor

temperatures in drier regions

  • The only effective outdoor cooler in

tropical regions (Hot & Humid)

  • Automatic start-up, shut-down
  • Self-maintaining capabilities
  • Remote monitoring
  • Weather-sensitive operations
  • Internet-based dash-board control

AIRBITAT CITY COOLER

Transforming working environments

  • 8 Airbitat Smart Coolers deployed at SATS Aero

Laundry

  • Existing conditions on the ground averages at 34-

36 oC due to heavy heat load from machinery

  • Airbitat City Cooler achieved a consistent 8-10oC

temperature drop (from 34oC to 24oC)
