Energy Saving 400t Cross Flow Closed Cooling Tower with Copper Coil for Data Center. Closed - loop coil internal circulation completely isolates the process medium from outside air. It avoids water contamination, reduces scaling, lowers equipment wear and minimizes medium loss. Multiple shell options: Mg - Al - Zn plate, 304/316 stainless steel. 304 stainless steel/copper coils pass 1.0 MPa pressure test. 304SS impeller spray pump for long service life. Auto switch air - cool / air - spray mode by water temperature. Fan and spray pump auto start - stop. Optional VFD configuration to cut operating costs. Consistent cooling performance regardless of ambient conditions. Custom low - noise fan sets for noise - sensitive sites. Modular design for simple inspection and repair. Factory - assembled or modular supply. 48 - hour nationwide on - site service to minimize downtime. High - performance coil structure delivers fast heat dissipation, rapid temperature drop and stable cooling output under heavy - load conditions. Optimized fluid and air channel design reduces power consumption. Competitive overall cost brings good return on investment for your project.
