GWA-UN5 Pure Water | Ultra Pure Water
● Inlet requirements: Urban tap water, temperature: 5-40 ℃, pressure: 0.1-0.5Mpa, conductivity value<1500 μ s/cm
● Water production method: Three outlets, producing pure water (tertiary water), secondary water, and ultrapure water respectively
● Type introduction: There are four types including basic type, analytical type, biochemical type, and combination type, which are:
GWA-UN4/UN4-F/UN4-S/UN4-C
● Features: 1. Wide adaptability to water sources, using a two-stage reverse osmosis desalination process, very suitable for use in high salt areas (such as Northeast, Northwest, Inner Mongolia, coastal cities, etc. in China)
2. Three independent water intake modes are designed to fully meet the various water requirements of the laboratory, allowing for easy access to primary, secondary, and tertiary water at any time
3. Add high-capacity DI package components to provide a more suitable water source for the ultrapure water package, greatly extending the ultrapure water supply
The service life of the water bag reduces the service life of consumables
4. Imported original materials and components are used in important water production processes such as ultra pure water bag mixed bed resin and terminal filters to ensure water quality
● Function: Automatic Function: Microcomputer control, blue backlight, 16 × 4 character LCD with real-time display system
The water quality status; Dual channel water production and real-time online monitoring of water quality, achieving graded water extraction
Automatic flushing of water, RO membrane and the entire system, automatic water storage in the tank, and automatic prompts for each
GWA-UN5 Pure Water | Ultra Pure WaterSafety function: Automatic protection when source water pressure is low: Automatic/manual operation mode
Automatic shutdown alarm function: when low pressure, when full water is taken, when tap water stops
