Abstract: A method for aseptic heating of a liquid product in a heat exchanger unit in a UHT system is described. The heat exchanger unit is a tubular heat exchanger, in which an indirect heat exchange on a wall takes place between the liquid product and a heating medium by a single heating medium flow with a heating medium inlet temperature flowing in a heat-releasing heating medium chamber between a heating medium inlet and outlet of the heat exchanger unit running countercurrent to a flowing single product flow guided in a heat-absorbing product chamber between a product input and output of the heat exchanger unit. A total heat exchanger path is formed between the product input and output, in which the product flow is heated from a product input temperature to a product output temperature. At least the product output temperature and the heating medium inlet temperature are monitored and regulated.
