a. The maximum operating temperature is a calculated function of the interaction between operating pressure and pH, ensuring safe and efficient operation across varied scenarios.
b. The maximum operating pressure is determined by both the temperature and pH of the inlet water. For scenarios where inlet water temperatures exceed 35°C or pressures surpass 69 bar, consulting with your account manager is advised for expert and tailored guidance.
c. The continuous operation pH limit is precisely determined based on the inlet water temperature and operating pressure to ensure optimal functionality and performance.
