Bench type: 51*38*57cm, 30-35kg;

Floor type: 55*42*115cm, 40-65kg.

Packing size

Bench type: 63*47*69cm, 32-37kg;

Floor type: 64*52*125cm, 42-67kg.

Working Process:


1. Pre-treatment system: PP cotton + AC +G-PHOS;

1.1 5um PP cotton: filtrate sediment, silt, rust, suspended matter, algo, colloid and other particles.

1.2 Active carbon filter: adsorb free chlorine, pigment, smell and parts of microorganism.

1.3 G-PHOS: prevent formation of CaCO3 and MgCO3 and change hard water to soft water.

2. RO membrane: It has high removal rate more than 99% for high valent ions, colloids, bacteria and organic matter (including endotoxin) with molecular weight greater than 300Dalton.

3. ZYDC-II Ultra pure system: Ion exchange resin using H + exchange cation out the water in the filter ,using OH- exchange anions out the water  , the replaced H + and OH- combined to produce H2O, ultra-purified column filling the United States Dow UPW-450 Ultra-pure water for nuclear grade resin, the water resistance of up to 8-10 MΩ.cm. 


Fully automatic microcomputer double RO ZYDC control system.

1. Multi-level operation menu.

2. Backlit Liquid crystal display( Resolution:240*128; Size:66*33mm).

3. Real-time animation mode display.

4. Perfect management functions like RO and ultra-pure water making, water taking,system circulation and disinfection,etc.

5.Ultra-pure water circulation to extend the life span of consumable parts within ultra-pure water purification system.

6.Automatic RO membrane anti-fouling flushing and manual forced flushing procedures to extend the life span of RO membrane.

7.Comprehensive system maintenance and safety alarm:

8. Equipped with USB Host interface to support historical alarm records and water taking record data export function, to facilitate the later access to historical operation conditions data.

9.Adopt more advanced, user-friendly membrane push button to take water.

10.Semi-transparent medical grade PP material do not produce secondary pollution.

11.Humanization design of manual/automatic water taking mode,Timing(1-99min),customization water taking (10-18.25MΩ.cm)
