a. The maximum operating temperature is intricately linked to the operating pressure and pH levels.
b. The maximum permissible operating pressure is sensitive to the temperature and pH of the inlet water. If the inlet water temperature surpasses 35°C and/or the inlet water pressure exceeds 69 bar, do not hesitate to contact your dedicated account manager.
c. The pH limit for continuous operation is contingent upon the inlet water temperature and operating pressure.
