WDE

WDE is available in displacement version.
The units blow out the cold air close to the ground at low speed (<1 m/s).
Due to the low speed at which the air is flowing, a “pool” of cold air forms
on the floor.
This cold air is drawn in by fans integrated in the server rack as a function of the heat load, and the heated air is expelled upwards. Because this metod prevents hot and cold air from mixing, the diplacement unit can draw the air at 30°C, instead of at 25°C as was previously the case.

Free Cooling
At low outside temperature, cooling is direct with outside air.
The outside air is conveyed into the container when the air flap is open.
Therefore when outside temperature are low, energy intensive compressor
cooling is not necessary.

EC Driven Compressor
Efficient telecommunications shelter runs 24/7, but the operational conditions can change throughout the day and the year.
The WDE compressor with EC driver monitor and adapt the cooling capacity to the actual heat load.
This allows a relevant energy saving and higher efficiency. even at partial loads.
