a. The pinnacle of operating temperature is intricately linked to the operating pressure and pH levels.
b. The apex of operating pressure is dependent on the temperature and pH of the inlet water. Should the inlet water temperature surpass 35°C and/or the inlet water pressure exceed 69 bar, please promptly consult with your dedicated account manager.
c. The pH threshold for continuous operation is inherently connected to the inlet water temperature and operating pressure limitations.
