It's a fact: a healthier environment in your bird house means healthier birds. And healthier birds mean more profit for you, whether you have broilers, breeders or cage layers.

Big Dutchman can provide you with an integrated environmental system, configured to keep your house running at peak performance. With 70 years of experience, innovation and leadership in the industry, Big Dutchman is uniquely qualified to design a system for you that maintains a clean, temperature controlled environment that, in turn, consistently produces uniformly healthy birds. Easy to maintain and controlled from a central location, your new environmental system from Big Dutchman will keep you, your employees, and your flocks all breathing easy for years to come.

To ensure stable control and outstanding environmental conditions for the birds, a ventilation system is required that utilizes air intake and exhaust air components, heaters, evaporative pad cooling, and a fully automatic control.

When minimum ventilation mode is required, Big Dutchman recommends that their customers use a negative pressure ventilation system with wall (or ceiling) air inlets distributing air evenly over the entire length of the house. Fresh air enters the house and mixes with the warm house air. This method leads to uniform temperatures as well as provides good distribution of air at bird level.

If the ventilation system is working in tunnel mode during high outside temperatures, intake air enters through the tunnel inlets. Air is drawn through the house by powerful fans located at the opposite end. This high-speed fresh air produces a wind-chill effect on the bird. Due to the uniformly high air speed at bird level, the temperature is reduced. If the outside temperature dictates, the wind chill effect may not be adequate. At this temperature and higher, evaporative pad cooling is recommended to cool the air as it enters the house.

Note: Big Dutchman tests the performance of every model fan. All fans with test numbers should perform as indicated when properly maintained (reports are available upon request). Our fans are tested by BESS Labs or in our AMCA fig 15 test chamber. The test chamber was designed and built to exacting AMCA/ASHRE standards. A regimented calibration and verification schedule is followed. Be assured, Big Dutchman fans provide the performance you require.
