"Today marks the first complete week from installation of the new Filter Pot Micro. We are excited to show you the results at 1 full week. The closed loop AC Chilled Water system was professionally, and thoroughly, cleaned and flushed through prior to installation and still the Filter Pot manages to capture impurities within the system. During commission a 20micron cartridge filter was installed as we continuously improve water quality towards industry best practice, 5micron.
