Air conditioning for server and comms rooms

A server or comms room is one of the few spaces where cooling isn’t about comfort at all — it’s about keeping equipment alive. The kit generates heat every hour of every day, and if cooling fails you risk overheating, damage and downtime. That makes reliability the whole game.

What makes server rooms different

  • Constant heat — equipment runs 24/7, all year, including winter.
  • Tight control — both temperature and humidity need holding within limits.
  • High stakes — a cooling failure can mean equipment damage and lost service.
  • Resilience — critical rooms need backup so cooling continues if a unit fails.
  • It’s about equipment, not people.
Why ordinary comfort AC isn't enough

A standard comfort system is designed to switch off when a room is empty and isn’t built to control humidity or run continuously. A server room needs precision (close-control) cooling: continuous, tightly controlled, and — for anything critical — with redundancy built in (often “N+1”, one more unit than strictly needed) so a single failure doesn’t take the room down. A small comms cupboard might be served by a dedicated unit running continuously, but the same principles of reliability and resilience apply.

Systems we’d recommend: precision/close-control cooling — the proper solution for server rooms, comms rooms and data centres.

Compliance: F-gas obligations apply, and for critical rooms, planned maintenance is essential rather than optional.
