    Dry Type Transformer

    Dry Type Transformers in Illinois

    Dry type transformers stay cool by using circulating air, eliminating the need for liquid coolant. They function in moist or dry conditions so that you can use them inside or outside. Their pollution-free functionality makes them an excellent choice for spaces with sensitivity to liquid or chemical contamination. Benefits of choosing our dry type transformers for your company in Illinois include:

    • Exceptional materials: We only use the best materials, which contributes to the impressive longevity of our transformers.
    • A low risk of fire: We reduce flammability by coating our coils with varnish that helps them resist moisture.
    • Long warranties: We offer a five-year warranty on new dry type transformers, an upgrade from the industry-norm one-year warranty.

The secure setup often includes a steel cabinet to house the transformer, which may be outside. We have transformers available from 500 KVA to 2,500 KVA. We stock three-phase units, but we can also build single-phase systems, and we make every transformer by hand. Choose from a range of accessories, such as:

    Custom Bus Work and Retrofit for Transformers in Illinois

    Transformers may need replaced when they reach the end of their life span, become overloaded or start demonstrating maintenance issues. Growing power needs can also render old transformers obsolete. When you get a new transformer and remove the old one, we can retrofit the new one to fit into the existing industrial transformer footprint.

    Our custom bus work creates connections that work for your new transformer within the available space. We can reduce the replacement costs by reusing some of the old parts. Our team fabricates the bus bars and places them correctly, and we guarantee a perfect fit.
