Thanks to the concerted efforts of all employees, Aigre Tech has successfully upgraded the chiller system of its flash welding machine for rails. The cooling water pressure has been increased from 0.1-0.6 MPa to 2.5 bar, and the heat dissipation capacity has been upgraded from 8460 kcal/h to 12900 kcal/h. Additionally, the cooling method has been enhanced from air-cooled to a combination of air-cooled and water-cooled, significantly improving the heat dissipation function of the welding machine and enhancing the work efficiency of the rail welding machine!
