SEE Cooling recommends dry coolers with speed-controlled EC fans due to their low power consumption and quiet operation, for example the AIA VX2 range. They come in standard sizes optimized to use with SEE Rack.
In a system with ground collectors the dry cooler is used for free cooling for over 80% of the year depending on the geographic location, transferring to geothermal energy when outdoor temperatures reach 15 to 20°C.
In systems with Chillers the dry coolers are in operation for both free cooling and, due to outdoor temperature conditions, for condensing heat dissipation from the chillers.
