THERMO-KOOL/Mid-South Industries Inc., was established in 1960 in Laurel, Mississippi. With only a handful of employees, the company's founders set out to provide the best quality walk-in in the industry. Today
THERMO-KOOL walk-ins are installed throughout the United States and in many foreign countries. The pride of master crafters has been handed down through the years and has helped to build and maintain the quality reputation of THERMO-KOOL walk-ins.

In 1975, with over five times the original number of employees, the company was moved to its new modern manufacturing facility in the North Laurel Industrial Park. After several expansions, this spacious plant on a ten-acre site is designed to accommodate the increased production necessary to keep up with THERMO-KOOL's ever-increasing sales volume. Yet, when the need arises, it still allows for each panel to be custom fabricated to the customer's special requirements.

In addition to expanding the company's manufacturing space THERMO-KOOL's Comptroller's Office was opened in 2000, in the heart of downtown Laurel to house the company's accounting, data processing and credit departments.

Staffed with experienced design, sales, and production personnel, THERMO-KOOL strives to continue to offer new product developments and consultant and design services to its customers.
