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.

RoMan’s Water-cooled, fully potted transformers can be closely-coupled to the load helping to reduce electrical losses in the power delivery system, while eliminating the need for mounting cabinets. Closer to the Heat Source

SINGLE PHASE WATER-COOLED TRANSFORMERS Single phase transformers are manufactured to meet the electrical specifications of your facility and application. The transformers are engineered to provide operational reliability while operating in industrial working environments.

SCOTT-T WATER-COOLED TRANSFORMERS Scott-T transformers provide a balanced three phase

distribution of power to be used in two-phase load applications. The transformers are made in two identical configurations, allowing partial spares to be used across an installed line.

THREE PHASE WATER-COOLED TRANSFORMERS Three Phase transformers provide three phase distribution of power to the loads. Multiple configurations including Delta and Wye are available. Various mounting options are available to meet your space and size requirements.

STACK-UP SAVES SPACE Our transformer size allows them to be stacked-up and installed next to where the heat source is needed most. This reduces the need for costly transformer rooms.

RoMan transformers can be mounted on top or below the platform helping to replace large cabinetry space.

RoMan transformers can replace this footprint.

BENEFITS Because our transformers are custom-designed for your application, they electro-mechanically integrate with your power. Smaller in size and lighter in weight, they become a component of your structural system closely coupled to the heat source. This results in a substantial reduction of total energy consumption, installation, maintenance and capex costs.

MECHANICAL MOUNTINGS RoMan offers custom design and manufacturing of mechanical frames and mounting stands for all of our transformers, as well as water-cooled and air-cooled secondary conductor and isolation devices.
