R-717, commonly known as ammonia, is an industrial refrigerant that has been in use for many years due to its exceptional cooling properties and environmentally friendly characteristics. Its applications include:

• Cold Storage Warehouses: Large industrial cold storage facilities use R-717 to maintain extremely low temperatures for the preservation of food and other products.
• Food Processing Industry: Ammonia is employed in cooling and freezing processes within food production plants, ensuring the quality and safety of food products.
• Ice Rinks: Ammonia is used in the cooling systems of ice rinks to create and maintain a smooth ice surface for sports and recreational activities.

Environmental impact:

• Ammonia has zero ozone depletion potential and a very low GWP, making it an eco-friendly choice for large-scale refrigeration and cooling applications.
