Pumpable ice technology
Pumpable ice (PI) technology is a technology to produce fluids or secondary refrigerants, also called coolants, with the viscosity of water or jelly and the cooling capacity of ice. Pumpable ice is typically a slurry of ice crystals or particles ranging from 5 to 10,000 micrometers (1 cm) in diameter and transported in brine, seawater, food liquid, or gas bubbles of air, ozone, or carbon dioxide.
