The choice for the right ventilation solution depends on your specific situation. The type of
barn, its location, dimensions, specific climate conditions , lay-out inside, systems in use etc. ,
all influence the right choice to maximize the best result for your livestock.
Abbi Aerotech helps you to design the right solution that saves you
money and guarantees the best conditions in your dairy barn for animal comfort and for your profit.
Dairy cows are very sensitive to heat stress, which can cost the dairy farmer over EUR 250,00-EUR 300,00 per cow per year.
Higher producing cows show even more signs of heat stress. There is increasing evidence that relatively low temperatures can lead to depressed feed intakes, lower milk yields, reduced fertility and increased risk of mastitis.
Heat Stress is linked to ambient temperature and to relative humidity.
The temperature-humidity index, or THI, is the common indicator for heat stress.
While the heat stress threshold was previously set at a THI value of 72, new studies show that a THI of 68 already effects the milk production, health and reproduction of high yielding cows.
Simple tips to reduce the negative impacts of heat stress on dairy cattle:
1. Provide adequate shade.
2. Provide cooling with fans.
3. Supply enough fresh and clean water.
4. Modify feed rations to increase energy supply and decrease heat load on the cow.
5. Add sprinklers/soakers and/or misters/foggers when possible.
The New Generation Abbifan 140 XXP 31
• The quietest
• The greenest
• The most energy efficient
This fan guarantees optimal air velocity and air distribution (LFL Germany), extremely low energy consumption, and precise, reliable control.
This highly energy efficient Abbifan is equipped with a high quality direct drive permanent magnet motor with integrated electronics for perfect speed control.
The Wave propeller is mounted directly onto the motor shaft. This completely eliminates the traditional belt drive, ensuring that slip is fully excluded.
Thanks to the in house development of the new motor suspension and the use of high strength ABS industrial plastic instead of hollow stainless steel tubes, this fan is genuinely exceptionally quiet.
Compared to the already very quiet XXP 21, this results in an additional noise reduction of 2 dB(A) — almost halving the perceived sound level!
EXPANSION OF A SUCCESSFUL VENTILATION CONCEPT!
The successful energy efficient ABBIFAN 140-XXP 140 cm fan now has a smaller variant: Abbi-Apex 36-AXP-21. Specially developed for low barns. The Abbi-Apex 36-AXP-21 ventilator has extremely low power consumption and is easy to regulate.

State of the art motor technology now available and affordable!
The easy‑to‑operate Abbi DCC‑Vision is the Abbi New Generation climate controller that fully automatically manages all processes involved in optimising the barn climate.
The Abbi DCC‑Vision features the same proven and reliable technology as the Abbi DCC‑Touch, while taking ease of use and functionality to the next level.
• Advanced Abbi software
• Fully automatic control of fans, misting and soaking
• Control possible based on the THI index
• Fans controllable in two separate groups
• Integrated modules for misting and soaking
• Easy reading of current operating values
• LED system status indicator
Also in the milking parlour, additional air movement ensures cooling on hot days. Not only the milker, but also the milking cows take advantage of the additional air movement. The cows stay calm, due to the presence of fewer flies.
The compact and efficient V50 series fans are stepless controllable. They have an air capacity of 4800-8700 m³/h. These fans blow horizontally over the cows and are suitable for an area of ca.30-50 m. Optionally they are equipped with guards.
The PV600 is a ceiling fan for use in the milking parlour. The fan ‘presses’ the air down and ensures optimal air distribution during hot and cold periods.

Everyone thought it couldn’t get any better — we continued to innovate!
We are therefore proud to once again introduce improvements that truly matter.
In addition to the fact that a fan must move barn air at sufficient speed to improve the barn climate and help prevent heat stress, it is equally important to actively reduce noise stress. Cows are particularly sensitive to noise!
By increasing the use of high‑quality recycled raw materials, we have further reduced the ecological footprint of our Abbifans.
As a result, the Abbifan is almost fully circular.
With longitudinal ventilation, the fans are mounted behind each other along the barn’s length.
The Abbi-Simply is our answer to the market demand for a simple-to-use, compact, manual ventilation controller with 5 speeds! The Simply bridges the gap between the multifunctional, fully automatic Abbi DCC-Touch climate controller and the manually operated, stepless mono (speed) controller.

Natural ventilation is a good way to ventilate cattle barns. However, on hot days with temperatures above 20°C, cows start having trouble to lose heat and additional air movement must be provided! This improves the heat release of the animals and thus reduces the risk of heat stress. It is important to start ventilating early; low air velocities already suffice to shift the lead-up to heat stress and while the temperature rises, the air velocity is increased proportionally.

Cross ventilation provides for fresh outside air in the barn, which significantly improves the barn climate. Furthermore, the cubicles are ventilated longitudinally, which increases the cooling effect for the dairy cattle. With longitudinal ventilation, the fans are mounted behind each other along the barn's length.

Fans can also be placed in the outside wall to draw outside air into the barn through cooling panels. This method, the so-called tunnel ventilation system, can realize temperature reductions of as much as 8 to 12°C! A good cooling system produces an air velocity at animal height of at least 2.5-3.0 m/sec throughout the barn. While the temperature of the air does not drop, the wind chill at this air velocity means that the animals experience a temperature that is 2 to 4°C lower.

Besides cooling the barn using Abbi fans, additional cooling is possible through water. A spraying bracket with high-pressure (60-70Bar) spraying nozzles can be mounted to the fan, with a time clock or special regulator ensuring regular water atomisation. The very fine droplets evaporate quickly, lowering the air temperature by some 3 to 5°C.
