An evaporative cooling system works by the water circulating in the system.
The evaporation cools the surrounding air, flutes (holes) in the cooling pads and allow the air to pass through the pads, this cools the air as it travels in poultry house.
Properly maintained evaporative cooling pads can bring the temperature substantially down as compare to outside temperature.
This results into improved performance with reduced operating cost.
If the flutes (holes) on the cooling pad are clogged, air cannot pass properly & results into reduced no cooling effects.
Dirty pads results into increased static pressure thereby…
Decreases air speed and cooling effect
Improper house temperature
Slower air exchange which increases leakage
Increased operating cost
Cooling becomes worse by wetted pad
Decreases pad life
Changes the pH which weakens pad resins
Increases risk of contamination (bacteria & mould)
Major sources of clogging of cooling pads
Mineral scales
Minerals present in water get deposited when water is evaporating
Dust coming along with wind also blocks the cooling pad, this reduces cooling capacity of the pad by blocking the air or by blocking normal water flow, so evaporating does not occur properly.
The warm & wet environment is the perfect breeding ground for microbial growth such as algae, fungus & bacteria
