Some are adopting positive or negative pressure ventilation. Others are installing filtration systems. In either case, PMSM fans are ideal for maintaining conditions in these barns. Thanks to the constant torque provided by PMSM fans, they can adjust to pressure changes almost instantaneously to maintain a consistent environment. TRIAC drives lack the torque to adequately deal with these pressure changes, and simple on/off fans have difficulty maintaining constant pressures in a barn. Cutting Energy Costs with New Technology Although energy savings are often lower on the priority list for producers when designing a ventilation system, PMSM fans can significantly improve the bottom line due to drastically lower electricity usage. As mentioned, PMSM fans can reduce energy costs by up to 90 percent, and the rate of return will likely increase in the future. Energy costs have gradually risen over time, and this trend isn’t likely to change. The push to transition to renewable energy sources may cause steeper increases going forward. PMSM fans and advanced whole-house controllers are not only wise investments now, but they can also help position pig producers for the future. This is especially true since the latest controllers offer easy software updates, preventing the risk of them becoming obsolete anytime soon. So, whenever the next challenges arise, adapting to them may be a breeze when using the latest ventilation technologies. Outdoor fans at pig farms play a crucial role in maintaining a healthy and comfortable environment for the pigs, providing ventilation, temperature control, humidity management, and energy efficiency.
