The Ice. Maker can build at least 19 lbs. (8,6 kg) supply
of ice in 3 hours or it can produce an entirely new
supply of 50 lbs. (22,7 kg) in 8 hours. The Defrost

water temperature reaches 20°C, and reactivate the
compressor to build an ice supply which is evenly
distributed around the cold plate.
Cardioplegia Water Supply
The system will provide water to cool clear or blood
cardioplegia. Three pump speeds allow variation of the
cooling rate of the cardioplegia by changing the water
flow rate. Three water supply modes are available to
accommodate different heat exchangers and demands.
