a. The maximum operating temperature is intricately linked to both the operating pressure and the pH level.
b. The maximum operating pressure is intricately dependent on the temperature and pH of the inlet water. For concerns regarding inlet water temperatures exceeding 35°C or pressures surpassing 69 bar, please reach out to your dedicated account manager for tailored advice.
c. The pH limit for continuous operation is closely related to the inlet water temperature and pressure conditions.
