About RDI Systems

Refrigeration Design Innovation Systems (RDI) was purchased from Randall Dyess by Kolpak in 1985 and moved from Waxahachie, Texas to Parsons, Tennessee in 1986.  The product brought from Texas was the RDI horizontal rack design which consists of multiple condensing units in a single housing. This design can provide refrigeration for multiple loads and is available from a 1-1 unit up to a 2-12.


We still produce those reliable models today and RDI continues to develop new and more innovative designs. Models like our RDI 120 Series  (designed to work in high ambient conditions), Duo-Pak (cooler and freezer combo) and Multi-Pak Racks (engineered to order multi-circuit), all designed for reliability and ease of installation. We continue to design refrigeration systems that leads the industry in innovation, reliability and energy savings.
