Cooling Systems Treatment & Cleaning

COOLING TOWER MAINTENANCE

Cooling Tower is a tool to cool hot water from the condenser or ‘heat exchanger’ by contacting it directly with air by forced convection using a fan. In cooling tower maintenance, operators or users generally only use methods or use chemicals that are cleaners only.

4 problems that often occur in Cooling Tower systems are corrosion, scale, bacteria/moss, and also sediment. If the user only uses softener, filter or lime absorber, this can indeed prevent the formation of scale, but is not enough to prevent corrosion. Damage due to corrosion can occur in the Cooling Tower due to chemical / electromagnetic reactions from salts in the circulating water. And if corrosion has occurred, the corrosion products will become scale deposits and can become ‘food’ for the growth of bacteria/moss and some of them will become sediment or suspended solid. Over time, the cooling tower cannot work optimally and ends up being damaged.

That is the importance of using chemicals comprehensively (thoroughly) and not partial (only focusing on one problem). One problem can give rise to other problems (cooling square problems).

Since 1999, PT Zefa Valindo Jaya has been a manufacture of specialty chemical, Aquaright, best chemicals to give solution for cooling tower problems.

Scale
Solution : Aquaright CTS 504, CTS 505

AQUARIGHT  CTS  505  is  a  blend  of  organophosphorus compounds,  selected  polymer  and  dispersant,  designed  to  control corrosion  and  prevent  scale  deposition  in  large  recirculating  open cooling systems operating on medium or hard make -up waters

Corrosion
Solution : Aquaright CH 10 N

AQUARIGHT CH 10 N  is a liquid corrosion and  scale  inhibitor for sealed cooling system and chilled water circuits using  distilled, softened  (Total  Hardness  <  50  mg/L  as  CaCO 3),  or  fresh  water. Effective  even  where  oxygen  may  be re-entrained in the circulating water. Suitable for most  metals including copper and  aluminium. AQUARIGHT  CH  10  N  should  normally  be  used  with  an effective  biocide  (but  not  when  associated  with  a  fresh  water generator producing water for drinking and culinary purposes).

Bacteria or Moss
Solution : Aquaright CA 202, CB 303

AQUARIGHT CB 303  is liquid biocide based  on isothiazolone  and is    a    broad    spectrum    biocide    that    is  effective  at  very  low concentrations in controlling both the planctonic  and surface growth of bacteria, fungi and algae in the cooling water system. And have been used specifically for water treatment and paper mill  applications.

Precipitate or suspended solid
Solution : Aquaright CTS 504, CTS 505

Dispersant that designed  to  control corrosion  and  prevent  scale  deposition. May be dosed direct to the system either
neat  or  diluted  as  required  in  a  mixing  tank.  Usage  of  a metering pump is strongly  recommended.

Why AQUARIGHT? Chemical Aquaright contains high quality polymer materials and was developed specifically as an antiscalant and corrosion prevention agent in cooling tower systems. Contact us for more detail, free consultation and free survey visit.
