ENGINEERING CHALLENGE

Designing Continuous Cooling for Mission-Critical Infrastructure

Unlike industrial production where thermal loads fluctuate with manufacturing cycles, data centers generate a constant heat load every second of the day. Any interruption to condenser water circulation can compromise cooling performance and threaten IT availability. Lohabour engineered a centralized cooling tower system with redundant hydraulic equipment, PLC + BMS automation, and scalable infrastructure capable of supporting continuous 24/7 operation while allowing future expansion.

BEFORE — CONVENTIONAL COOLING INFRASTRUCTURE

  • Limited cooling capacity for future expansion
  • Higher risk from single-point equipment failure
  • Manual equipment sequencing
  • Restricted maintenance flexibility

AFTER — REDUNDANT COOLING TOWER PLANT

1,500 RT
  • Two modular cooling towers with N+1 redundancy
  • Automatic PLC + BMS equipment sequencing
  • Balanced condenser water distribution
  • Continuous 24/7 heat rejection
  • Expandable infrastructure for additional data halls
