Established in 1957, UNIVERSAL DYNAMICS manufactured dehumidifying equipment for the U.S. government and its independent contractors. Dehumidifiers were installed and utilized to preserve valuable, vital material at missile sites, warehouses and on "moth-balled" ships. As the drying of plastics material became increasingly important to large scale production, UNIVERSAL DYNAMICS entered a joint venture with the Rainville Company, through Dupont, to supply drying equipment for plastics material. Supplying drying equipment for the plastics industry rose and government contracts declined as UNA-DYN moved forward.

By 1960, UNA-DYN was fast becoming a lead supplier of dehumidifying dryers, resulting in the need for a larger facility. Relocating to Woodbridge, Virginia, provided much needed space to facilitate building the first large capacity dryers needed by the plastics industry for processing of resin material in refrigerator liners and other large parts formed from sheet material.

In 1965, UNA-DYN was sold to one of its largest customers, The Rainville Company. Manufacturing continued under the Rainville name in the Virginia facility and at the Rainville New Jersey facility until the early 80's. In 1982, The Rainville Company sold its New Jersey machinery operation, along with the Rainville name, and adopted the UNIVERSAL DYNAMICS name for the Virginia facility headquarters.

Continued growth and technological advances mandated an expansion and site improvements in 1992, which included an additional 25,000 square foot warehouse. UNA-DYN'S development of gas fired heaters for existing dryers and crystallizers brought an alternative energy source and increased energy efficiency to the plastics industry.
