Description

Product Introduction

Engineered for extreme AI server racks (100kW+ per cabinet), the DWW1200-125A manages massive heat loads with 1200kW capacity and 105 m³/h secondary flow. Its 1+1 redundant pumps and stainless steel heat exchanger isolate facility water from dielectric coolant, protecting GPUs. Seamlessly integrates into air-liquid hybrid micro-modules via PLC Modbus TCP/IP.


Key Parameters:​

  • Model: DWW1200-125A (1200kW), DWW500-80A (500kW), DWW200-50A (200kW)
  • Secondary Interface: DN125 (1200kW), DN80 (500kW), DN50 (200kW)
  • Temp Control: 40/50°C secondary, 35/45°C primary
  • Footprint: 1200W x 1400D x 2200H mm (1200kW model)
  • Electrical: 16.5kW rated power, 460-480V 3Ph 60Hz ready.
    Applications:​ GB200/H100 GPU clusters, AI training centers, high-performance computing (HPC), and large-scale AIDC facilities.
