a. Maximum operating temperature is intricately linked to operating pressure and pH levels for optimal performance.
b. Maximum operating pressure is contingent upon the temperature and pH of the inlet water. Should the inlet water temperature rise above 35°C or the pressure surpass 69 bar, please consult your account manager for tailored solutions.
c. Continuous operation pH limits are dependent on the inlet water temperature and operating pressure for sustained efficiency.
