Electrical Descaler for Cooling Tower
Function of Cooling Tower Electrical Descaler
 
  Efficient separate and remove water scale
  Anti corrosion, scale and rust
  Kill bacterial, algae
 
 
Appearance of Cooling Tower Electrical Descaler
 
 
Work Principle
Before use, water in cooling tower exists mainly as macro-molecule, which contains free oxygen, bacteria, organisms. Those are main reason to cause pipe rust, corrosion.
In use, we makes use of electrolysis technology to create high frequency power, which break up water molecules.
In this process, water molecules breaks as of electrolysis, creates active oxygen which can oxidize organisms, bacterial into CO2, and exhaust. Meanwhile, part free oxygen combines with free oxygen into oxygen, exhaust.
Finally negative pole gathers with lots active hydrogen, which helps cooling tower water stays in a strong reducing environment.
Remark: Red ball stands for free oxygen, black ball stands for bacterial, organisms.
 
 
 
 
 
How does water scale harmful to equipment?
Water scale mainly consists of carbonate, magnesium, occupy 60%. Other kind scale includes sulfate, silicate, iron, 
occupy around 10%. 
Dust sludge around 30%. Scale largely reduce heat-exchange and reaction efficiency, which largely increase power 
consumption. Take center air-conditioning as example. 
Once scale 0.3mm forms at heat ex changer will cause 20% heat loss, increase 10% energy consumption.

 0.0mm  92.77  0   0%
 0.3mm  73.68  21%  10%

Application
 
Electrical descaler widely used at industry, agriculture, environmental protection field, and daily life. Example like: power 
plant, steel plant, cement factor, pharmaceutic, paper printing, coal and mining industry, etc.
 
In center air conditioning, electrical descaler helps solve scale, sludge sedimentation, bacterial problem. Center air 
conditioning systemused at factory, hotel, shop mall, office building etc. 
 
In heat supply system to solve scale, rust problem. Such like: electronic factory, module factory, heating supply system. 
 
In boiler water treating, it can replace ion exchange softener equipment. 
 
 
 
 
 
Feature
1、Save Energy, Protect Environment
Electrical descaler can works under high efficiency, low power consumption. As of its constant working, which ensure 
constant electrolysis environment. It reduces over 4% power consumption. Easy to clean, no need drain, friendly to 
environment. 
 
Take 250KW center air conditioning system as example. 
① Install descaler, it will save 54% electricity if sale thickness 1.6mm.  (Save 340200 KWH)
② Install descaler, it will save 31% electricity if sale thickness 0.9mm.  (Save 195300 KWH)
③ Install descaler, it will save 7.9% electricity if sale thickness 0.2-0.3mm.  (Save 49770KWH)
 
2、Low Cost Maintenance  
Take 400RT air conditioning as example. 
Electrical descaler input power is 350W, only cost USD500 operation cost. Easy to clean as well, around 15M one time.
 
3、 Long lifetime
Electrical descaler can separated chemical corrosion, long its lifetime. 
 
4、 Easy Operation 
Clean dirty collector 2-3times. 
After using 2months, water can achieve best condition. Even if stop using for one moth, recycling water systemwon’t 
appear stop working or alarm. 
 
Technical Parameter and Specification 
Small scale water supply plant, home well usually have high hardness, bad taste. Electrical descaler enables to reduce 
water total hardness, total alkaline and total bacterial cluster. It keeps drinking water clean and safe. 
 
Water water treating plant usually has troubles of fast sediment sludge. Electrical descaler helps to reduce treating cost, 
absorb most heavy metal ion meanwhile, kill bacterial, protect environment.

Notice Installation 
1. Electrode bar should immerse in water
2. Keep control box as near electrode as possible, rain proof.
3. Don’t shut on/off frequently after connecting wire.
4. Close power supply before clean electrode 
5. Clean electrode:
① Disassemble 3 pieces screw and bolts
② Take off both ends cover
③ Separate negative and positive electrode
④ Use nitrohydrochloric acid to clean electrodes 2-3minutes, wash with clean water till clean 
⑤ Fix electrode at cooling tower for work
⑥ Wear protection glass, anti acid gloves when cleaning electrodes. Ask help for doctor if acid liquid touches skin.
