WORKING PRINCIPLE:

SIVIS is a packaged Air Handling Unit (AHU) that uses ambient air as
refrigerant fluid to cool the Data Center.
The machine is equipped with two cooling sections, each with filtering section,
air/air heat exchanger and supply fans with variable air-flow.
Each cooling section handle the 50% of the total air flow of the system.
The cooling effect is obtained inside the cross-flow air to air heat exchangers
where the ambient air flow and Data Center airflow never come into direct
contact ensuring treated air purity.
The ambient air flow is ensuring by dedicated fans with variable flow.
