COOL Max Controllers

The COOL Max System by Tunnel Plus

The COOL Max Control System is a versatile, user-friendly solution designed to optimize airflow with precision and ease. Featuring an intuitive touchscreen interface, it allows for seamless setup and stage adjustments, ensuring effortless operation.

Developed by farmers for farmers, the COOL Max system prioritizes accuracy and simplicity. It intelligently regulates airflow based on real-time temperature and humidity readings, ensuring optimal conditions exactly when and where you need them.

The Ultimate Holding Area Controller

The COOL Max system is engineered to be the most advanced holding area controller on the market. Designed for maximum efficiency and flexibility, it offers multiple programmable time slots for precise operational control.

With the ability to manage multiple AC fan stages (on/off), regulate fan zones using 0-10V signals, and incorporate our proprietary misting and light rain options, the COOL Max system delivers exceptional cooling performance, even in extreme conditions.

Whether you operate a tunnel-ventilated barn or a naturally ventilated barn with circulation fans, the COOL Max system provides precise airflow control through multiple stages of ventilation. It efficiently manages circulation fans over the stalls, ensuring consistent air movement for optimal conditions.

Additionally, our advanced misting system distributes water throughout all designated areas without contributing to your lagoon, maintaining a controlled and efficient cooling environment.

What Can The COOL Max System Do For You?

  • Heat stress can cause a 10-25% drop in milk yield, directly impacting farm profitability. A well-ventilated barn helps keep cows cooler, reducing stress and preventing production losses.

    Cooler cows also eat more, maintaining higher energy levels and increasing milk output. Research shows that improving barn ventilation can boost milk yields by 4-8 lbs per cow per day during hot weather.

    Farms that upgrade to a Tunnel Plus System have seen production losses cut in half, ensuring a healthier, more productive herd.

  • Proper ventilation in dairy barns can increase milk components like butterfat, protein, and overall milk quality by improving cow comfort, reducing heat stress, and enhancing feed efficiency.

    Higher milk quality leads to higher milk premiums.

  • Heat stress doesn’t just lower milk production—it also negatively impacts reproduction rates, making it harder for cows to conceive and maintain pregnancies. Proper ventilation plays a crucial role in improving fertility by keeping cows cool and reducing the physiological stress that disrupts reproductive performance.

    High temperatures can cause early embryonic loss, leading to more open cows and longer calving intervals.

    Research shows that when cows are kept cool, conception rates improve by 10-20%, especially during summer months.

  • Proper ventilation in dairy barns is crucial for reducing diseases and sickness in cattle by improving air quality, controlling humidity, and minimizing heat stress.

    Poor ventilation leads to buildup of ammonia, carbon dioxide, and dust, which can irritate the lungs and cause respiratory disease.

    High humidity creates a breeding ground for mastitis-causing bacteria and fungal infections, while moisture buildup in bedding increases somatic cell counts (SCC) and leads to more udder infections; however, proper ventilation keeps bedding dry, reducing the growth of E. coli, Streptococcus, and Staphylococcus, which cause mastitis and other infections.

  • Many challenges in the dairy industry can be traced back to poor holding area conditions, impacting both animal welfare and operational efficiency. The COOL Max system has been rigorously tested and proven to be the most effective solution on the market for dramatically improving holding area conditions.

    By optimizing airflow and climate control, the Tunnel Plus COOL Max System helps reduce or even eliminate key issues, creating a healthier and more productive environment for your operation.
