Commercial industrial refrigeration involves the use of a combination of temperature and humidity control systems, air filtration systems, ventilation systems and insulation to maintain optimal temperatures and humidity levels in commercial or industrial facilities. The aim is to create an environment that meets legal requirements and protects whatever the facility has been constructed to house — whether it’s food, medical supplies or pharmaceuticals. This type of refrigeration helps to preserve the items stored within and prevents spoilage or spoil-related damages.
