‘Cool cows directly by ‘wetted forced-air evaporative cooling’

… ‘How do we do this?

Designed to perform ….

‘High-velocity air delivered by the CowKool fans break through and penetrate the cow’s heavy coat of fur ..’


‘The user-defined misting cycle turns ON allowing small water droplets to be placed directly on the skin surface of the cow..’


‘The misting cycle turns OFF allowing the fans to blow high velocity air over the skin surface of the cow evaporating the water thus

reducing the body temperature of the cow.’


‘This ON/OFF/ON/OFF misting cycle is repeated over and over.’






‘The duration of the misting cycle is completely user-defined.

For HOT and DRY areas where evaporative cooling is the most effective, the misting cycle can be programmed to be

relatively long …’


‘… Such as misting ON for 3 minutes …’




‘… And OFF for 1 minute …’


‘… ON for 3 minutes …’




‘… OFF for 1 minute …’


‘For HOT and HUMID areas where evaporative cooling is less effective, the misting cycle can be programmed to be

relatively short allowing cooling to be accomplished more by high-velocity air. Smaller, lower-flow misting nozzles can

also be used.

‘In February 2003 the Hof Hasharon dairy began the move to their present location, and by June 2003 the relocation of the three dairies that make up the present dairy was complete. The cows were averaging 30 kg (66 lbs) of milk per day and their body temperatures were 39.5 degrees X (103.1 degrees F). In August 2003 we installed and started operating the CowKool system. Within 10 days the feed consumption increased and the milked produced increased to 33 kg (72.8 lbs) and the body temperature of the cows decreased to 38.7 degrees C (101.7 degrees F). on average while the daily humidity was 80-95% and wasn't much lower during the night (we are located less than a mile from the Mediterranean Sea and always receive a sea breeze). The CowKool system that cools the cows and the nearby surroundings yielded a strong cooling effect. The dry matter intake during the toughest months (June – August) was 22.5 kg (49.6 lbs). Last year (2005) our herd average was 12,500 kg (27,558 lbs). Average daily drop during the hard summer months is roughly 15% (you have to take into consideration that we try and spread the monthly pregnancy rates to conform with the quota system here in Israel). I am very satisfied and believe in the CowKool system. The system is dependable and helps me persevere with the hard summer months. Uri Goldberg,General ManagerHof Hasharon Dairy, Israel

‘The CowKool System provides all of the flexibility to easily adjust your cooling as climatic conditions such as heat and humidity change throughout the summer period. This flexibility provides the most effective and yet safest

cooling for all types of dairy operations.’
