A method of circulating fluid to adjust a temperature of a material comprises providing a pressurized fluid source operative to adjust the temperature of a fluid and to push the fluid out through a supply port at a supply temperature and draw fluid in through a return port at a return temperature. A conduit is arranged in proximity to the material and the fluid is circulated through the conduit in alternating forward and reverse directions. An apparatus is provided for periodically reversing the direction of fluid flow through the conduit.
