摘要：Apparatus for retarding freezing of a liquid including a tank of pressurized gas and a gas conducting line leading to a point beneath the surface of the liquid to generate and release bubbles into the liquid to create fluid circulation therein to retard freezing. The gas conducting line may include elongated, twisted wires coated with a tight-fitting gas sealing coat, the resistance to through-flowing gas presented thereby effecting a metering of the gas to release it at a predetermined rate below the surface of the liquid. Additionally, an escape chimney is also included which presents a vertically oriented gas conduit having holes at top and bottom with the gas bubbles being released therebetween to stimulate additional fluid circulation.
