Why heat stress in stables is a problem
and how you can work against it
Heat stress in livestock can lead to significant health problems such as increased early embryonic mortality and reduced fertility. In addition, the farm is burdened by loss of performance due to significantly reduced milk yield and deterioration of milk constituents. Our CAT3000® tube ventilation system provides targeted cooling and a constant supply of fresh air to effectively regulate the barn temperature and reduce heat stress. The flexible system can be adapted to specific requirements and uses waste heat from biogas plants for heating in winter, thereby reducing energy costs. With fully automatic temperature control, optional exhaust air chimney and heat register, we optimally promote the well-being and productivity of your animals.
CAT3000® – the best barn climate solution for animal welfare and profitability.
CAT3000®
Hose ventilation
against heat stress in stables
The CAT3000® hose ventilation system has been specially developed to meet the requirements of modern animal husbandry. It ensures a constant supply of fresh air to your animals through precise air supply. The benefits are clear to see: the targeted cooling helps to keep heat stress, which puts a strain on the entire organism, under control.
Advantages that convince
Better barn climate, fewer diseases, lower costs
Ideal climate in the barn with precisely optimal air conditions
The ventilation is constantly stable and ensures even, draught-free air distribution from the beginning to the end of the hose. Individually adjustable fresh air volumes and speeds create optimum conditions in different areas of the barn.
Fresh air for low-emission stables
The hose ventilation prevents the circulation of contaminated stable air and protects animals and humans from pathogens. In addition to even air distribution, the system ensures low levels of harmful gases (ammonia) in the barn.
Fast profitability through maximum animal welfare
The CAT3000® system promotes the well-being of your animals, which leads to a significant reduction in veterinary costs and ensures consistent performance. As a result, the system pays for itself within a very short time.
Corrects weather-related and structural factors
The system corrects for seasonal and structural factors that could otherwise lead to an irregular and inadequate supply of fresh air.
Veterinary costs and use of medication are significantly reduced
A significant reduction in germs in the air we breathe leads to a noticeable reduction in respiratory infections - in some cases by up to 80 percent. The improved air quality significantly reduces veterinary costs and the use of medication.
Longevity of the livestock is increased
Relieving your animals' immune system also reduces their energy consumption, which in turn has a positive effect on growth and health. The improved stable air therefore also contributes to the longevity of your livestock.
Versatile in use
CAT3000® from Dr. Knopf & Oswald
The CAT3000® system ensures targeted cooling and a constant supply of fresh air for your animals. Depending on the size of the barn, type of housing and animal species, we adapt the system individually to your specific requirements. With fully automatic temperature control and an additional cooling reserve for the hot summer months, Dr. Knopf & Oswald offers a comprehensive solution for barn ventilation. An exhaust air chimney and a heat register are optionally available to further optimize the adaptation to the needs of your animals.
Cattle and calves
The CAT3000® tube ventilation system from Dr. Knopf and Oswald effectively protects cattle and calves from heat stress by ensuring a uniform and draught-free supply of fresh air. The improved air quality reduces infections and increases the well-being and growth of cattle and calves.
Horses
For horses, the CAT3000® system offers ideal ventilation that supports respiratory health and increases performance. The targeted air circulation ensures a pleasant stable climate that reduces stress and promotes the vitality of the horses.
Pigs
Pigs benefit from the constant supply of fresh air provided by the CAT3000® system, which reduces exposure to harmful gases such as ammonia. This leads to better health and a higher overall resistance of the animals.
Sheep and goat
The CAT3000® system significantly improves the air quality in stables for sheep and goats. The reduction of pollutants and the even distribution of fresh air promotes animal health and minimizes the risk of respiratory diseases.
Poultry
Poultry requires precisely metered and even ventilation to ensure optimal growing conditions. The CAT3000® system provides constant air circulation that reduces moisture and pollutants, improving floor conditions and enhancing animal health.
Why Dr. Knopf & Oswald?
From practice for practice
Our CAT3000® system is the result of intensive research and development in our own practice. Under the motto “From practice for practice”, we offer sophisticated systems that meet the highest standards of quality, functionality and durability.

Customer testimonials
Würth family
We have converted our farm in Switzerland to the proven CAT 3000 hose ventilation system from Dr. Knopf and Oswald in order to ventilate our barn efficiently. One reason for this was the great flexibility of the system, allowing it to be optimally adapted to the individual conditions of our barns and ensuring that the ventilation works smoothly and comprehensively even in complex barn structures. Particularly noteworthy is the draught-free supply of cooling fresh air to the animals. This guarantees that each of our cows in the barn is evenly and optimally supplied with fresh air, which is crucial in the summer months.
We would like to thank you for the excellent service, the professional expertise and the uncomplicated handling of the project
Hermann family
Thanks to Dr. Knopf and Oswald, we have finally found the perfect solution for our calves. Our new Topcalf calf hutches, both double and single, make our work easier and are a bright, friendly home for our calves. Equipped with easyClean in each case, we can muck them out quickly and easily. We are also impressed by the flexibility and stable construction. We will always be happy to recommend the Topcalf calf hutches from Dr. Knopf and Oswald.

Mathias Rottler
"CAT3000® is the best solution for my barn. Each cubicle is evenly ventilated and the individual adaptation to the conditions in my barn have convinced me. My cows are also much healthier. I used to have a considerable increase in sick cows in summer, which has decreased significantly since installing the tube ventilation. My cows' metabolism has benefited greatly from the tube ventilation."
