LOGICA SYSTEM

LOGICA is the newest generation system for high density server rooms, where the thermal load of the servers is particularly high. LOGICA is beyond the concept of hot & cold aisles and provides localized cooling, focusing on hot spots caused by the servers, through a cooling doors system installed directly on the racks.

Maximum energy efficiency results in a sharp reduction in data center running expenses. A hydronic system called LOGICA is built around the patented NEGATIVE. Leak Prevention System with Pressure Technology: Servers are completely shielded from potential water leaks.
