Transformer cooling is not optional it’s critical. Yet, when it comes to cooling fans, many facilities still operate on outdated beliefs that cost them efficiency, uptime, and energy.
If you’re still using conventional AC fans or assuming “airflow is airflow,” it’s time to reconsider.
Here are 5 persistent myths about transformer cooling fans and the facts you need to know.
Myth 1: “All Fans Cool the Same”
Reality: Not all fans are engineered for transformer applications. Generic axial or pedestal fans lack the airflow control, durability, and thermal response required for transformer cooling.
BLDC fans, like those from Airzon, deliver stable, targeted cooling with adjustable speed and high static pressure essential for effective transformer ventilation.
Myth 2: “Fan Type Doesn’t Affect Transformer Life”
Reality: Improper cooling directly impacts winding temperature, insulation degradation, and transformer lifespan.
BLDC fans reduce thermal stress by maintaining optimal temperature even under fluctuating loads—extending equipment life and reducing maintenance cycles.
Myth 3: “AC Fans Are Cheaper and Just as Effective”
Reality: AC fans may cost less upfront, but they draw higher power, generate more heat, and lack control.
Airzon BLDC fans consume up to 55% less energy, last longer, and offer precision speed control delivering long-term ROI and better performance.
Myth 4: “Once Installed, Cooling Fans Don’t Need Re-Evaluation”
Reality: Transformer loads and ambient conditions change. Aging fans lose performance. Outdated AC fans can’t keep up.
Regularly reassessing your fan system—and upgrading to BLDC models ensures cooling efficiency keeps pace with operational demands.
Myth 5: “Overcooling Is Better Than Undercooling”
Reality: Overcooling isn’t efficient it’s expensive and unnecessary. It can also cause thermal cycling, stressing materials and insulation.
Airzon’s fans integrate with temperature control systems to deliver smart cooling based on real-time demand no more, no less.
