In commercial refrigeration, designated numbers are used to grade the climate, with each number indicating that the grocery cooler or supermarket freezer can operate at a specific ambient temperature and relative humidity (RH). This classification system helps business owners make informed choices for their supermarkets, convenience stores, grocery stores, commercial kitchens. The climate scale is divided into four different levels:
– Climate Class 3: This special supermarket freezer is capable of operating in an environment with a maximum ambient temperature of 25°C and a relative humidity of 60%.
– Climate Class 4: This grocery cooler is designed to function best in an environment with a maximum ambient temperature of 30 degrees Celsius and a relative humidity of 55%.
– Climate Class 5: Designed to meet the needs of extreme conditions, this supermarket freezer can operate in areas with a maximum ambient temperature of 40°C and a relative humidity of 40%.
