Additional benefits of secondary coolant systems are improved product quality and reduced shrink in fresh foods, opportunities to use more efficient and environment-friendly refrigerants, and to reduce demand and dependence on qualified technicians during installation and operation.
The environmental impacts of refrigerants leaked into the atmosphere, such as ozone depletion, resulted in global and local environmental regulations that were unprecedented two decades ago in the supermarket industry. Additionally, unknown or potentially negative impacts have raised public awareness to the extent that new regulations are constantly introduced while existing regulations are becoming more restrictive.
