Cooling towers

Six cooling towers form part of the LLF recooling system to control the temperature in the wind tunnel. 
Specifications per tower:

Cooling capacity 3,419 kWh
Water flow 420 m3/h
Water inlet temperature 31.0 oC
Water outlet temperature 24.0 oC

Chemicals are added to the cooling water to prevent corrosion and microbiological growth. The recooling system is remotely controlled by the wind tunnel operators in the control room.
