a. The maximum operating temperature is intricately connected to both the operating pressure and pH level, allowing for optimal performance adjustments.
b. The maximum operating pressure is contingent upon the temperature and pH of the incoming water. In scenarios where the inlet water temperature exceeds 35°C or the pressure surpasses 69 bar, please engage with your dedicated account manager for tailored guidance.
c. The pH limit for continuous operation is dependent on the temperature of the inlet water and the operating pressure, ensuring stable and safe operations.
