Lowers Skin Temperature by Over 3 Degrees... Coupang Logistics Service Expands "Cooling Fog" Nationwide

First in Industry to Install Large-Scale Enclosed Cooling Zones
"Cooling Fog" Lowers Skin Temperature by Over 3 Degrees During Work

Coupang Logistics Service (CLS) announced on July 30 that it will expand the nationwide installation of "cooling fog" systems in work areas where air conditioning is difficult to install.

Last year, CLS became the first in the industry to implement "large-scale enclosed cooling zones" in logistics workspaces, taking into account their unique characteristics by combining cold air leakage prevention curtains and ceiling-mounted system air conditioners at sub-hubs (parcel sorting terminals) across the country. Simultaneously, CLS began testing the "cooling fog" system—an installation that sprays a fine mist to lower the ambient temperature—for workers in open-structured areas.

Thermal imaging camera measurements of facial skin temperature before and after operating the cooling fog revealed that the surface temperature of the skin decreased by more than 3 degrees Celsius. The cooling fog sprays ultra-fine water particles of less than approximately 7 micrometers in size, which is less than one-tenth the diameter of a typical human hair (about 70-100 micrometers). These particles rapidly evaporate in the air, absorbing ambient heat and effectively lowering the temperature of the skin's surface.

CLS is expanding the use of cooling fog nationwide, tailoring its implementation to the specific work conditions of each delivery camp in order to prevent heat-related illnesses. In camps where roofs are exposed to direct sunlight, tests are also underway to install cooling fog systems on the roofs, applying the same principle—by lowering the surface temperature through ultra-fine mist that touches the skin—to the surfaces of the workspace itself.

A CLS representative stated, "We are introducing systems and programs that provide tangible support for delivery drivers affiliated with subcontracted delivery agencies, such as the industry's first large-scale enclosed cooling zones and a customized health management program overseen by medical professionals. We will continue our efforts to ensure delivery drivers have a safer and more comfortable work environment."
