Value Delivered

Shambaugh was awarded another fast-track Design-Build retrofit project through its established partnership with Edy’s/Dreyer’s. Shambaugh provided innovative NH3 refrigeration system design, retrofitted and expanded all plant systems and infrastructures in less than six months.

Client Objectives

The Dreyer’s Novelty Ice Cream plant in Dallas needed to install a 950 ton, high-stage refrigeration system in addition to the existing 1100 refrigerated tons to double production capacity.

Scope of Services

Shambaugh’s single-source responsibilities included process, refrigeration, controls, mechanical, electrical and fire protection.

The scope of services included enhancing the current refrigeration control system, as well as upgrading the existing compressor room, the addition of a 25,000-square-foot freezer and hardener room, the completion of nine ice cream lines, renovation of the existing process piping, which included raw receiving, HTST pasteurization, mix and filling lines; the installation of piping on new silos, flavor tanks, re-melt, ice cream freezers, fillers and CIP system; three new electrical services were added—power and control wiring for two new production lines—accomplished with minimal interruption of manufacturing operations.


Value construction engineering, use of prefabricated components, alternative code designs, and the use of Shambaugh’s qualified site project construction management and labor forces, resulted in significant cost and time savings for the client.
