A temperature control system for dispensing installations in maintaining different types of liquids at different temperatures includes feeding from container to dispenser each different type of liquid through pipe bundles (14, 16) insulated from each other. Each bundle (14, 16) has a cold water pipe (18) passing therethrough. The cold water pipes (18) are in circuit with a cold water supply. Temperature monitoring means (22, 24, 26) is provided to ascertain the temperature of the liquid inside one or more of the bundles (14, 16) and to compare said temperature with a datum temperature. The temperature monitoring means (22, 24, 26) are in electrical circuit with a pump (30) to feed water to one or each cold water pipe (18) and with valve arrangements (20) to control flow of water through the cold water pipes (18). |
