Sprinkler Trucks Transformed into 'Cooling Guardians' to Shield College Entrance Examination Venues with Freshness**
As the college entrance examination (gaokao) begins, cities across the country are taking multiple measures to create a comfortable testing environment for examinees. Recently, Kailifeng pure electric sprinkler trucks have appeared around examination venues in many cities, assisting with cooling through refined operations. Equipped with high-efficiency permanent magnet synchronous motors and ultra-fine atomizing nozzle systems, these trucks can transform water into delicate water mist with a particle size of less than 80 microns, achieving **precise cooling of 3-5°C** in areas around examination venues. During operations, the vehicles operate efficiently while ensuring road surfaces remain slightly wet without water accumulation, alleviating the sweltering heat under the scorching sun and avoiding disruptions to traffic order. They have created a "mobile cool space" for examinees and parents, safeguarding the gaokao with technological prowess and winning widespread praise from citizens.
