a. The peak operating temperature is intricately linked to both operating pressure and pH levels, ensuring optimal performance under all conditions.
b. The maximum operating pressure is dependent on the precise temperature and pH of the inlet water. For conditions where the inlet water temperature surpasses 35°C or the inlet water pressure exceeds 69 bar, kindly consult your dedicated account manager.
c. Continuous operation's pH limit is directly related to both the inlet water temperature and operating pressure, harmonizing performance and longevity.
