A python (10) for maintaining the drinking liquid flowing in lines therein at a predetermined temperature has a drinking liquid delivery line (11) adapted to deliver drinking liquid, a coolant line (14) adapted to carry coolant and insulator tubing (15) arranged in that order concentrically outwardly. The central drinking liquid delivery line (11) is in thermal contact with the surrounding coolant line (14). The coolant line is surrounded by insulator tubing (15) in such a way as to restrict the free movement of both the drinking liquid delivery line (11) and coolant line (14). The drinking liquid is thereby maintained at a predetermined temperature by the temperature of the coolant and the effect of the above-mentioned concentric arrangement of drinking liquid delivery line (11), coolant line (14) and insulator tubing (15). |
