Lanier Technical College Ammonia Refrigeration Program  
Established 1999 – 16 Years of Education Excellence  
Lanier Technical College is home to one of only a few Ammonia Refrigeration Training programs in the USA.  
Hands-On Training

Lanier Technical College’s Ammonia Program is not a "Simulated" program. We instruct with a "LIVE" Ammonia Lab. We offer several courses related to Ammonia Refrigeration, which train workers to operate and maintain an ammonia refrigeration system and how to respond if the system malfunctions.

Georgia's Only Ammonia Refrigeration Program

Lanier Technical College is the Premier Ammonia Refrigeration Training School! Our Ammonia Refrigeration Program is backed by a State Technical College that is regionally and nationally accredited and is approaching 50 years of Quality Industry Training. Lanier Technical College is a Unit of the Technical College System of Georgia. The Lanier Technical College Ammonia Refrigeration Program started in 1999 as a collaborative effort with Lanier Technical College, the Georgia Institute of Technology (Georgia Tech), and Food Industry Partnership (formerly FoodPAC) - joining forces to launch this innovative training program. We quickly joined two trade organizations - the Refrigerating Engineers & Technicians Association (RETA) and the International Institute of Ammonia Refrigeration (IIAR), and in 2009 Lanier Technical College partnered with the Global Cold Chain Alliance (GCCA), the International Association of Refrigerated Warehouses (IARW) and the World Food Logistics Organization (WFLO) to become the Official IARW-WFLO Ammonia Refrigeration Training Program!
