Cooling

• At ambient temperatures above 23°C and if the outside air has suitable humidity, cooling by adiabatic evaporation is used, so that air supplied to the rooms meets the prescribed parameters.
• If the outside temperature drops below 20°C, incoming air is mixed with air from the hot aisles. Before entering rooms, air is also moistened to the ideal 40 to 60% RH. That eliminates conditions for the creation of static electric charge.
• Air cooling and circulation in data rooms is ensured by reliable redundant air conditioning units with an Emerson water heat exchanger.
• The unique cooling system was designed and implemented in collaboration with E.D.T.

Hot and cold aisles

• Digitalis uses the concept of hot and cold aisles with the complete separation of hot and cold air. Cold air is distributed under the raised floor and hot air dissipates through the ceiling.
• We close the hot aisles and not the cold ones, which contributes to even more reliable cooling, since in the case of a short power outage of the air conditioning (e.g. during the start of a diesel generator) there is more cold air than hot air in the room.
