Application
In the production of ultrapure water (WFI), the process begins with aqua purificata being fed into the steam separator. The aqua purificata evaporates there and is fed into the condenser. Evaporation is effected by a heat exchanger supplied with saturated steam. To ensure that the heat exchanger is always covered with aqua purificata, reliable level detection is required. The pressure inside the steam separator must be kept constant in order to achieve maximum efficiency.
