The unit holds as many as five cups of water to form a solid block of ice overnight. The unit’s lid is designed to limit warm air exposure, enabling ice to stay frozen for as long as 6 to 8 hours. Additionally, freezer gel is contained in the sides and bottom of the Histo-Cool, which keeps solid or crushed ice frozen.
