In the critical battle to protect global health, the final mile of temperature control determines the efficacy of life-saving vaccines. As COVID-19, HPV, and polio vaccines journey across continents, maintaining precision thermal stability (-70℃ to +25℃) isn't just a requirement—it's a matter of life. This is where INTERNATIONAL HAOTIAN TECHNOLOGY excels.

As a pioneer in high-performance vaccine cooler boxes, HAOTIAN TECH shatters limitations with its "Zero-Drift Thermal Guard" technology. Our medical cooler boxes integrate aerospace-grade vacuum insulation and AI-driven temperature monitoring, sustaining ±0.5℃ stability for 120 hours even in extreme environments (-40℃ to 50℃), exceeding WHO's stringent cold chain compliance protocols.

The breakthrough lies in our advanced PCM phase change materials. HAOTIAN's medical-grade PCM ice packs utilize micro-encapsulation technology to achieve customizable phase transition zones (2-8℃/-70℃), eliminating dry ice sublimation risks and thermal gaps. To date, over 37 national disease control centers have trusted HAOTIAN vaccine shipping containers for Ebola vaccine distribution, achieving a 0% failure rate in field deployments.

"From polar research stations to tropical outbreak zones—we ensure every vaccine arrives with dignity." This commitment fuels HAOTIAN TECH's innovation in pharmaceutical cold chain equipment.
