Industrial Chemical Cleaning & Water Treatment Services

We remove water scale, oil deposits, rust, sludge and algae from cooling towers, chillers, boilers, heat exchangers and production machinery using KCA chemicals. Clients pay only for the chemicals; on-site application by our technicians carries no service fee and can be scheduled at night or on holidays to avoid production disruption.

About Us

Industrial chemical maintenance since 2008

PT Sinar Karya Sejahtera (SKS) was founded in January 2008. Our head office and showroom are in Kapuk, Jakarta, with a branch office in Cikarang close to the Bekasi and Karawang industrial estates.

SKS is the official sole distributor of KCA chemical maintenance products in Indonesia. Our service goes beyond supplying chemicals. Our technicians survey your site, inspect the equipment, calculate the exact chemical requirement and carry out the cleaning to completion, with no separate service fee. We then help maintain your equipment through a scheduled water treatment program.

Most of our clients are manufacturing companies. We also serve hotels and hospitals whose cooling systems and utilities must operate continuously.

“SKS focuses on cleaning and maintaining machinery with the right chemicals, so your equipment performs at its best every day.”

Three service lines, one technical team

Chemical Cleaning & Descaling

Equipment that operates with water or oil accumulates internal deposits over time, including water scale, oil deposits, sludge, rust and algae. These deposits impede heat transfer, causing higher operating temperatures, increased power consumption and a greater risk of breakdown. We dissolve them with chemicals selected for the specific problem.

Heavy scale in boiler tubes before descaling
Chemical typeRemovesTypical use
Acid-based
+ corrosion inhibitor
Water scale (lime, calcium, magnesium), rust, sludge, algaeCooling towers, condensers, boilers, water side of heat exchangers
Alkaline
high pH
Water-soluble oil and grease depositsOil coolers, moulds, machine parts
Solvent-based
non water-based
Stubborn oil deposits on components that must not contact waterGear boxes, oil side of heat exchangers, electrical parts

Our acid cleaners contain a corrosion inhibitor, so they dissolve scale without attacking the metal. The method depends on the equipment: circulation flushing, dip tank soaking or spraying. Chemicals are supplied in 25 kg / 25 L pails.

“We choose the chemical for the case at hand, not one product for every problem.”

FAQ

Frequently asked questions

Is there a fee for the application service?

There is no service fee. Clients purchase only the KCA chemicals required, and our technicians' work is not billed separately. Site surveys within Greater Jakarta are also complimentary.

How long does chemical cleaning of a cooling tower or chiller take?

It depends on the unit size and how thick the scale is. After the survey we give you a clear time estimate, and the work can be scheduled around your shutdown.

Will the chemicals damage pipes or metal parts?

Our cleaning chemicals contain corrosion inhibitors, so scale and rust dissolve without attacking the metal. For sensitive materials such as aluminium and galvanised steel, we select a suitable product.

Can the work be carried out at night or on holidays?

Yes. We routinely work outside production hours so that your plant does not incur additional downtime.

Can we see a demo before buying?

Yes. We can run a demo or sample test at your site to prove the results.

How often does a cooling tower need treatment?

In a routine program our technicians visit twice a week for chemical dosing, and the water is analysed monthly. The frequency can be adjusted to your water conditions.

Do you serve areas outside Greater Jakarta?

Our main area is Greater Jakarta, including Bekasi, Cikarang and Karawang. We can serve other locations with additional transport and accommodation costs.

Can we buy the chemicals only?

Yes. KCA chemicals are available in 25 kg / 25 L pails. Technical data for each product is in the Products section.
