A thermal purge system includes a purge vessel into which is introduced hot gaseous refrigerant fluid from the outlet of a conventional chiller. A first coil having very cold refrigerant fluid flowing through it is positioned within the vessel so that much of the hot gaseous refrigerant fluid from the chiller is condensed upon contact with the coil. The condensate collects on the bottom of the vessel until it reaches a depth sufficient to initiate a syphoning action by an artesian well which returns the condensate to the chiller. Uncondensed gases are reheated and re-expanded external to the vessel and returned to the vessel through a second coil in heat transfer relation to the first coil so that further condensation occurs. Noncondensibles which remain after the reheating, re-expansion, and recooling are purged to the atmosphere.
