  • PN-L Series

  • TOP

  • Product feature:

Suitable for water quality in the whole country, the chassis adopts spray plastic process

System filter element adopts open mold injection technology and built-in chassis

Korean quick-connect filter column is easy to replace and maintain.

The electrical and waterways are completely separated to avoid circuit failure caused by moisture and water leakage.

Water quality online monitoring system to instantly measure the water quality of the produced water;

Automatic RO membrane anti-scaling flushing program, automatic shutdown of tap water, automatic water

cut off, automatic water supply in the storage bucket, automatic shutdown of the water storage tank.

The pipelines are all NSF certified and have water quality and water upgrade functions.

Equipped with a portable TDS pen, you can test TDS content, conductance, water temperature anytime, anywhere.

Colored touched screen, humanized operation interface make users completely monitor controller’s working status and real-time data.

ABS engineering plastic case, powder coating technology, with water quality and quantity upgrading function, self-priming door.

Open the door design before and after, it is quick and easy to replace the filter element, and the filter replacement can be easily completed without using any tools.

Inbuilt feed water pressure test gauge to real time monitor tap water pressure and filters blocking.

Lifetime of PP cotton, activated carbon filter, RO membrane and ultra purification columns can be set to display the elapsed&rest time of consumables. Automatic reminder for filter replacement to avoid water quality decreasing.

Perfect managing functions of RO&UP water making, circulation system and sterilization.

Feed water, RO and UP water three ways water quality sensor and five ways switches signal are accessed integrated, with functions of timing quantitative water taking.

Equipped with USB Host interface, it supports data export function of historical alarm record and historical water intake record.

Low-voltage 24VDC is used as the main power supply, which meets the safety regulations and meets the requirements of humid environment, and will not cause personal injury.

Can be with inner circulation system to ensure water quality keep at the highest level. ( optional)
