FIBER FORMING WATER-COOLED TRANSFORMERS
THE POWER TO TRANSFORM ™ RoMan Manufacturing ® is one of the world’s leading designers and manufacturers of AC water-cooled transformers and related specialty products. As a manufacturer of high-current, continuous operation transformers, we combine unparalleled knowledge and expertise with innovative technology, to deliver ready to use products to leading companies worldwide.
MELTING, BOOSTING AND FORMING Ideal for optimizing the melting, boosting and forming of glass, RoMan transformers are smaller in size and lighter in weight, allowing them to be closely coupled to the heat source. This helps reduce electrical vibrations, resulting in increased product quality and longer component life-cycles, while substantially reducing total energy consumption, installation and maintenance costs. RoMan GenFour Transformer With the launch of our GenFour Transformers, RoMan has introduced the latest technological advancement for the integration of fiber forming transformers and secondary bus systems. GenFour is designed for balanced electrical delivery and optimal heating of the bushing.
SHUNTS & BUS We offer a wide array of accessories and related specialty products to support our Water-Cooled Glass Transformers. The size and capability of our accessories can be designed to meet your application’s requirements.
LOWER RESISTANCE SHUNTS To optimize the secondary circuit electrical efficiency, RoMan press welded shunts offer lower resistance than traditional riveted designs, helping to minimize voltage losses and reduce current imbalances. From standard designs to customer specific parameters, our shunts will reduce costly problems associated with traditional secondary circuit voltage losses.
BUS—FEWER BOLTED JOINTS To maximize the efficiency of the entire system, RoMan offers custom-designed water-cooled bus integrated into your application. Through an exclusive design that reduces the need for unnecessary bolted joints, and a manufacturing process that only uses high-conductivity copper to insure low secondary circuit resistance, our bus bars allow installation closer to the heat source.
