Product Description

Medium Series Lab Water Purification System

 GB/T6682 -2008     PN-EN ISO 3696:1999


Lab water purification system is a kind of pure water making plant for testing and inspecting water in laboratories. and they are widely applied into Scientific research, College and University, Disease control, Environmental protection, Chemical industry, Foods, Animal husbandry, Brewing industry, Soil test, Blood center, Hospital, etc.

Performance &Advantages

According to the product design aim "good adaptability to raw water, high capacity water production, ultra-long consumables life, producing water quality is excellent and stable, system operating parameters is adjustable, can be matched with biochemical analyzer". Medium series lab water purifiers have the following special process configuration design:

Good adaptability to raw water, high capacity water production: 40L/H -200L/H


Except for the above targeted design, Medium lab water purifiers have another technical characteristics:

  • Pretreatment, RO, aftertreatment are integrated into one machine casing with universal wheel, installation and maintenance is convenient, with scientific structure configuration.
  • CPU automatic control PLC imported from USA, fault self-diagnosis sound and light alarm system, LED LCD screen can show the producing water quality online, the man-machine interface conforms ergonomics'  design, waterproof safe stainless water intake Key, etc
