The CryoBan grenade was originally designed as a fire suppressant. When detonated, Cryoban grenades rapidly caused everything in a radius of four meters to freeze. Used as a weapon, they could trap a person or object, and the cold itself could be lethal to living beings and damage equipment such as droids and vehicles.
The freezing effect was caused by a supercooled liquid that froze on contact. There was also a chemical agent present that absorbed heat.
