Pressurizer Heaters

Electric pressurizer heaters are used to control the pressure in the pressurizer vessel of PWR and PHWR reactors. These heaters are directly installed in the pressurizer vessel and they are electrically powered to provide the heat input required to maintain pressure control during transient conditions. The pressurizer heaters are designed and manufactured in accordance with ASME Section III, Class 1 and stamped NPT according to Code requirements.
