Superior Quality Furnace Duty Transformers

A furnace transformer is designed to increase or decrease AC voltage to suit the heating system's requirements. It transfers electrical energy from the circuit to the induction process, ensuring proper voltage regulation.
Depending on the furnace's needs, the transformer can either amplify or reduce the electricity within the system. These transformers were originally manufactured in Vadodara, Gujarat, and have become popular over time. To date, their performance remains unmatched.

Fault Detection

If a transformer issue is suspected, look for these warning signs:

  • Visual Indicators

    Burn marks or bulges may signal the need for a replacement. Some cases require only repairs, which professionals can handle.

  • Humming and Vibrations

    While some noise is normal, excessive humming may result from the iron core and laminations contracting or expanding.

  • Circuit Breaker Trips

    If the furnace transformer is faulty, the circuit breaker may trip to prevent a voltage surge that could damage furnace components.

  • Power Supply Issues

    The system may shut down to protect itself from power supply damage. Verify if this is a normal occurrence or if the power supply requires repair.

Key Benefits

  • Withstands high mechanical and thermal stresses

  • Easily manages high currents

  • High low-voltage variation, ideal for furnace applications

  • 100% standby capacity

  • OFWF cooling system

  • Resilient against stress from electric arcs

Frequently asked questions

Furnace-duty transformers provide heating systems with steady power delivery by carefully controlling voltage. In sectors like power plants, chemical plants, and engineering facilities, this increases overall process control, lowers downtime, and improves energy efficiency.

These transformers are designed to manage high-power loads, perfect for demanding applications like big industrial furnaces and railway operations. They have a rating of up to 15 MVA and secondary currents exceeding 100,000 A.

In addition to having protection systems up to 15,000 Amps, they have strong insulation and can tolerate significant mechanical and thermal strains. These safety precautions aid in preventing electrical malfunctions and power surges in delicate settings, such as those used in the manufacturing of chemicals and pharmaceuticals.

In wind and solar power plants, where steady power conversion is essential for reliable energy output, our transformers' AN (Air Natural) and AF (Air Forced) cooling systems ensure effective heat dissipation.
