a. Temperature and Pressure Correlation: Understand that the maximum operational temperature is intricately linked to both the operating pressure and the pH level.
b. Pressure and Temperature Dynamics: The upper limit of operating pressure is contingent on the inlet water's temperature and pH. For scenarios where water temperature exceeds 35°C or pressure surpasses 69 bar, please consult your dedicated account manager for guidance.
c. pH Limitations: Continuous operation's pH boundaries depend closely on the temperature of the inlet water and the corresponding operating pressure.
