The hot zoneYour Holding Area Is Costing You More Than You Realize.
Even holding areas equipped with fans and sprinklers can expose cows to considerable heat stress. Tight stocking density, uneven airflow, excessive humidity, and improper water application can cause core body temperature to rise—putting milk production, reproduction, and cow health at risk.
Reproduction Issues
Elevated body temperatures can lead to embryo loss and reduced reproductive performance, creating costly gaps in your herd’s production cycle.
Poor Herd Health
Health issues like lameness, pneumonia, infections, and mastitis will increase production downtime, require additional labor, and lead to high treatment costs.
Higher Operating Costs
Inefficient DIY fans and poorly controlled water systems waste energy and water without delivering consistent cooling—costing you valuable time and money.
Lost Milk Production
Heat-stressed cows often produce less milk—up to
10-15 pounds less per day in some cases. Milk quality and butterfat levels can also decline.
Heat stress in dairy cows can begin at temperatures as low as 68°F, especially when humidity is high.
The Heat Stress Impact.
❝ The holding pen is where dairy cows experience the most heat stress. ❞
The solutionOne Integrated System for Total Holding Area Cooling.
CowOasis™ is more than a collection of fans and sprinklers. It brings together every essential component needed to combat heat stress in one fully integrated cooling system. Each CowOasis™ system is custom-engineered for the size, layout, ceiling height, cow capacity, and environmental conditions of your holding area.
Cool the Cow, Not Just the Air Around Her.
01 · High-Powered Airflow
Airflow that punches through.
Industry-leading Ziehl-Abegg fans generate powerful cow-level airspeed that reaches through tightly packed groups and delivers cooling where it matters most.
110 years of German engineering. Made in USA.
Biomimetic blades modeled on barn owl wings—more speed, less noise.
Direct-drive EC motors—IE5 efficiency (highest rating).
Airspeeds reaching 40 mph. Highest air movement in the industry.
Four components, engineered together. Each one does a job the others can’t—so no cow gets left in a hot spot.
02 · Precision Water Application
Light enough to ride the airstream. Heavy enough to hit the skin.
The CoolMAX misting system applies precisely sized water droplets for effective evaporative cooling without unnecessary water use or oversaturation.
03 · Controls
“Set it & forget it” intelligence.
04 · Custom Designed
Engineered for your holding area, utilities, cow capacity, and cooling needs.
How it worksFrom hot spot to oasis in four steps.
Step 01On-site evaluation
We assess your existing system and identify airflow and water-application problems.
Step 02Custom engineering
Designed for the size, layout, ceiling height, cow capacity, and conditions of your holding area.
Step 03Install & commissioning
Our specialists install the system and optimize the controller settings on day one.
Step 04Automatic cooling
CoolMAX runs fans and water at the right intensity—every shift, without daily adjustments.
Intelligent controlsAutomatic Cooling Around the Clock.
The CoolMAX Controller continuously monitors temperature and humidity and automatically operates the fans and misting system at the appropriate intensity. Our specialists optimize the settings during installation and commissioning, giving you dependable cooling without daily adjustments or guesswork.
Monitors temperature and humidity 24/7
Professionally configured at install
Automatically adjusts fan speed as temperature changes
Summer & Winter Capabilities
Activates precision misting based on actual THI
Reduced dependence on employee adjustments
“After putting this system in our holding area, we just don’t see the milk losses we used to have during the summer. Plus, pregnancy rates remain stable. I highly recommend this system.”

Return on investmentAn Investment That Pays for Itself.
By limiting spikes in core body temperature, CowOasis™ helps protect milk production, improve reproductive performance, and support a longer, healthier productive life. For many farms, these benefits can allow the system to pay for itself in approximately 12 to 24 months.
