Heavy Duty Catalog

Particularly resilient REO components at a glance


With the new Heavy-Duty catalog, you have for the first time all REO components that meet the highest requirements, clearly arranged and modern at a glance. These include chokes, transformers, resistors, current transformers and complete solutions. In the case of complete solutions, the main focus is on the highly compatible support frame system, the REOFLEX Multiuse Frame. Thanks to the standardized support frame, rail components from REO can be mounted easily, quickly and very variably. For safe damping and suspension, vibration dampers can even be integrated into the unit as required.

Individual development

Customized product development


Individual product development at REO means achieving and maintaining parameters tailored to the customer’s needs, which would not be possible with standard products. Both the electrical parameters and the mechanical, constructive conditions are adapted. Thus, the customer receives exactly the product he needs for his application.

REO is not only a mass producer, but is particularly at home in the development and production of special niche solutions. In close cooperation with our customers, we develop ideas and technical solutions in small or large quantities, which, through their use in an overall system, take over tasks that are not covered by standard products on the market. In this way, we enable our customers to use state-of-the-art applications and innovative production processes without having to resort to standard products with limitations.
