Evaporative Cooling Systems

Evaporative Cooling Systems

Evaporative Cooling Systems are designed to remove latent heat from the air through moisture evaporation in poultry farming operations. These cooling systems control barn temperatures in the heat of summer. Evaporative cooling works by moving damp air through the animal space, collecting heat as it travels. During hot summer months, keeping birds cool is imperative to preserve their comfort, health, and productivity. Choose between a pad cooling system, a high pressure fogging system, or a combination of the two, for best results.

PolAir High Pressure Fogging


PolAIR High Pressure Fog systems atomize water into micro-sized particles that rapidly evaporate to reduce air temperature. Due to this evaporative cooling process warmth is extracted from the air used for the evaporation of water. The fog increases the relative humidity and suppresses airborne contaminants. PolAIR is the system that can effectively control the temperature and the relative humidity as needed in green houses.

The unique VAL-CO PolAIR nozzle is completely made from stainless steel and produces the finest fog giving the highest cooling effect without any condensation on the floor.

PolAIR is renowned for its high reliability and yearlong smooth operation with minimum maintenance. The systems operate at pressures of 1000 to 1500 psi (from 70 to 105 bar) with an average particle size of 10 – 15 microns. At mentioned pressures, the PolAIR nozzle atomizes 6,2 – 7,7 l/hour and 2,5 – 4,0 gr of moisture/m3 air.

All systems are individually configured, and tailor made to fit your situation.
