This realistic type of  training is very effective in teaching employees correct procedures while allowing them to also see the consequences of what could happen if they do not follow established operating procedures. Our program allows employees to fully participate in the training process, practice their skills and develop their knowledge.

Hands on Lab!!!

 The hands on ammonia based industrial refrigeration training at Garden City Community College offers a unique opportunity. Refrigeration engineers and technicians from food processing, meat packing, refrigerated warehousing, petro chemicals, pharmaceuticals, air conditioning and many other 21st Century applications have an opportunity to use real equipment for their training.

Ammonia refrigeration is the newest element in GCCC's Industrial Production Technology program. Other offerings include Pneumatics, Hydraulics, Electric Motor Control Centers and Programmable Logic Controls.
