a. The peak operating temperature is intricately tied to the operational pressure and pH levels, ensuring optimal performance.
b. The maximum permissible operating pressure is contingent on both the inlet water's temperature and pH. If the inlet water temperature surpasses 35°C or the inlet pressure exceeds 69 bar, please consult your dedicated account manager for tailored guidance.
c. Continuous operation pH limits depend upon the inlet water temperature and the operating pressure for seamless functionality.
