Displacement
Free Cooling

  • Dantherm Displacement Free Cooling for electronics cooling in small rooms Dantherm DFC

for Telecom rooms, shelters and enclosures.

The Dantherm DFC 350 and 450 are slim passive cooling units utilising the displacement free air cooling technology. The units are designed to remove excess heat from small rooms with electronic equipment, where the air is stagnant.

What is Displacement Free Cooling?

The Dantherm DFC units supply cool outside air to the bottom of the room. This forces the warmer air in the room to move up. This is known as displacement cooling, because the hot air inside the room has been displaced by a cushion of cool air.
 

When is the Dantherm DFC a good choice?

Displacement Free Cooling by Dantherm is most efficient under the following conditions:

  • In rooms up to 12m2
  • When the internal air is stagnant

Specific strengths of the DFC-solution

The units are less cost-intensive and more silent than traditional Free Cooling solutions, because they operate with lower air flows and fan speed. Furthermore, the DFCs are small in size, taking up a minimum of space in the room.
