Cooling Water Cleaning System

● It removes the scale which is fixed to the equipment of the cooling water system by using the principle  of electrolytic method. (Removes solid scales by using‘Electrolytic Technology’)

● This is Cooling Water Cleaning System which prevents scales from being generated at Cooling tower filler,  ci rculation piping, Evacon tube, etc. (Prevents re-gaining Scales on Pipes, Filter, Tubes etc)

● It removes the scale which is fixed in cooling towers and heat exchangers while preserving water  q uality and atmosphere. (Saving and improving the quality of water while it removes scale)

● It kills bacteria and microorganisms such as legionella and salmonella in cooling water, and removes green algae.  ( Reduces Bacteria and microorganisms (i.e as legionella and salmonel) and removes green algae)

● Using environmentally friendly products(DaJaBaRa), which has caused water pollution and environmental  polluti on by using existing high-risk chemicals, it excelled in environmental protection and energy saving after  installat ion. (Eco-Friendly by reduces using chemicals)

Installation Location

● CW Supply piping between cooling tower and heat exchanger

Processing Capacity (RT : Ton of Refrigeration)

● The processing capacity per unit of cooling water cleaning system should be greater than the replenishing  v olume of the cooling tower.

In the case of 500RT, the circulation volume of the cooling water is 390ton/hr,  so 390ton/hr x 0.012 = 4.68ton/hr (replenishment amount of the cooling tower).

The standard processing capacity per unit of 500RT is 5.0ton/hr and this is greater than 4.68ton/hr  w hich is the replenishment amount of the cooling tower and so, install 1unit of 500RT.

▶  Arresting Ca2+ (calcium ion), Mg2+ (magnesium ion), such as scale generating ions  dissolved in water onto cathode surface

- Maintaining the concentration to below the solubility - Preventing scale generation

▶ Inhibits generation of microorganisms production by radical hydroxyl and chlorine

- Inhibiting Slime

- Inhibiting green algae

※ Radical hydroxyl group : Strong chemicals for oxidizing with non-toxic character from the known substances  (flu

orine, ozone, chlorine)

▶  Anti-Corrosion

- Prevents corrosiion by changing cooling water into alkalescent water

DaJaBaRa - Expectation After Installation

1. Preventing and arresting various scales in the cooling water system

2. Dajabara inhibits various microorganisms occurrence by generating hypochlorous acid (HOCL)  with a sterilizing effect.

3. No need to stop the equipment in operation in order to remove the scales in the cooling water system.

4. 5~10% energy savings by improving efficiency of the Heat Exchanger

5. Coolant BLOWDOWN can be reduced water consumption by 70% to 80%.

6. Reduced input costs of disinfectants and microorganisms for cooling water cleaning
