Calcium Chloride is commonly used for skating and hockey rink refrigeration systems due to its effective performance in freezing point depression. It has a unique ability to lower the freezing point of water, which helps maintain the rink's ice surface at appropriate firmness even under varying ambient temperatures.

This compound is particularly advantageous because it remains effective in colder conditions compared to some other salts. It efficiently captures moisture from the air, allowing it to work well in environments where ice is crucial for performance and safety, like skating rinks.

Furthermore, calcium chloride's compatibility with the refrigeration systems, its ability to provide a reliable brine solution, and its relatively low cost contribute to its preference in these applications. Overall, its properties make it an ideal choice for maintaining the quality of ice in skating and hockey rinks.
