a. The maximum operating temperature is intrinsically linked to both the operating pressure and pH levels, ensuring safety and efficacy.
b. The maximum operating pressure is contingent upon the inlet water's temperature and pH. For scenarios where the inlet water temperature surpasses 35°C and/or the inlet water pressure exceeds 69 bar, please consult your dedicated account manager for guidance.
c. Continuous operation pH limits are influenced by the interplay between inlet water temperature and operating pressure.
