a. The maximum operating temperature is intricately linked to both the operating pressure and the pH levels, ensuring optimal performance.
b. The maximum operating pressure is contingent upon the temperature and pH of the inlet water. Should the inlet water temperature exceed 35°C and/or the inlet water pressure surpass 69 bar, please reach out to your account manager for further assistance.
c. The pH limit for continuous operation is carefully correlated with the inlet water temperature and operating pressure to maintain efficiency.
