Staying cool in the stable – effective cooling for dairy cows. The requirements for modern, animal-friendly dairy farming are constantly increasing. Animal welfare, health, and performance are the main focus. Heat stress in particular poses a major challenge for dairy cows: it affects feed intake, milk yield, fertility, and the general well-being of the animals. With the Lechler CowCool nozzle, we offer a proven and efficient solution for targeted cooling of dairy cows in the stable.

Double benefits with Lechler CowCool nozzles

Benefits for the cow

CowCool nozzles provide a significant contribution to animal welfare:

Reduction of heat stress: Targeted wetting effectively lowers the body temperature and stabilizes the cow's heat balance.
Maintenance of feed intake: Cows kept at a comfortable temperature eat more – a basic requirement for high milk yields
Stable milk production: Heat-related performance losses are significantly reduced.
Improved fertility: A balanced temperature has a positive effect on reproductive performance.
Cooling of critical body zones: The heart/lung region and the digestive tract – areas with high heat production – are cooled in a targeted manner.
Greater well-being and health: Less stress leads to calmer animals, better health, and higher lifetime performance.

Benefits for the farmer

The CowCool nozzle offers clear added value for agricultural businesses:

Ensuring economic efficiency: Stable milk yields during heat reduce heat-related drops in performance and safeguard the contribution margin.
Easy integration into existing stables: Installation above the feed fence prevents feed and cubicles from getting wet.
Automated operation: Saves time and labor thanks to automatic control.
High operational reliability: Large flow openings minimize the risk of clogging.
Low maintenance: Removable dosing bore enables quick and easy cleaning.
Durable and robust: Made from high-quality POM material for demanding everyday stable conditions.

Interval Sprinkling for Cooling Dairy Cows

The Lechler CowCool nozzle uses three cooling principles: direct cooling, evaporative cooling, and heat removal. In interval spraying for evaporative cooling, cows are targeted with larger water droplets so that the water penetrates down to the skin. The key is not to moisten the barn air, but to actually wet the animal. A targeted “soaking” with sufficient water enhances cooling further by directly removing heat from the body. The system operates in intervals: short spraying phases alternate with ventilation phases, allowing enough water to evaporate without creating unnecessary moisture in the barn.

Droplet size is crucial for effective cooling: only sufficiently large droplets penetrate the coat and reach the skin. The CC nozzle produces an optimal droplet spectrum for highly effective direct cooling – resource-efficient, field-tested, and designed for maximum performance.

Key Benefits of the Lechler CowCool nozzle:

Targeted soaking
Controlled and even water distribution
Efficient use of evaporative cooling
Optimal performance in interval operation
