In high-power transformers, excessive heat is a silent threat that directly impacts system reliability and longevity. The primary contributor to this heat is copper loss (I²R), with additional thermal load from hysteresis and eddy currents. If not properly managed, this heat can cause the transformer’s internal temperature to rise uncontrollably, leading to deterioration of insulation, reduced efficiency, and even catastrophic failure. That’s where our Transformer Cooling Fan Controller Panels come in—engineered to regulate and control forced cooling systems that maintain optimal operating temperature for both dry-type and oil-filled transformers.

• Automatic Fan Operation: Temperature-based automatic control using RTDs or thermistors.
• Manual Override: Allows manual fan operation in case of sensor failure or emergency cooling.
• Multi-Stage Fan Control: Fans run in stages depending on real-time temperature levels, saving energy.
• Dry-Type & Oil-Filled Compatible: Customizable for both transformer types and all major cooling standards.

• Alarm & Fault Indications: Visual/audible alerts for sensor fault, fan failure, or high temperature.
• Built-in Protection: Overload, short-circuit, and surge protections for enhanced safety.
• Panel Enclosure: IP54/IP65 enclosure with powder-coated sheet metal or stainless steel options.
• Flexible Mounting: Suitable for indoor or outdoor installation with top/bottom cable entry.
