Secondary refrigerant

Coolant can be divided into primary coolant and secondary coolant. A secondary coolant is generally non-toxic in small amounts, though larger amounts must be disposed of appropriately.

Primary coolant is used in a cooling system to lower the temperature of a secondary coolant, such as brine. The secondary coolant circulates through a cooling system and is cooled in a heat exchanger. The coolant can then be used for other purposes, for example the cooling of ice rinks. A secondary coolant is generally non-toxic in small amounts, though larger amounts must be disposed of appropriately.
