Chemical Supplier Salalah: A Descaler Batch from Barka Racking to Salalah Port

If your heat exchanger, chiller or engine cooling circuit in Dhofar is losing efficiency to scale, you need an inhibited acid descaler on site and a supplier who can get it there. As a chemical supplier Salalah plants, cold stores and vessels can order from, we hold descaling powder and liquid descaler in our Barka warehouse and deliver them to Salalah and Dhofar. Our two descalers, Safe Acid Descalex powder and Safe Acid Descalex Liquid, are the products southern buyers ask for most.

Chemical supplier Salalah: why southern buyers order from Barka

Search for chemical suppliers in Salalah, Oman and you mostly find directories and catch-all pages that list Salalah as one name in a long service area. A buyer at a Salalah Free Zone methanol or ammonia plant, a cement plant cooler line, a fish processing cold store or a vessel alongside at Salalah port needs something more practical: a named product, a part number, a data sheet and a delivery to the gate.

We keep stock in Barka and deliver south to Salalah and Dhofar. Several items for the same customer can be quoted together, and we confirm the delivery arrangements when we send the quote.

Which descalers we supply from Barka

Our descaling range has two products. The first is Safe Acid Descalex powder, part number RXSOL-40-1008-020. It is a heavy duty powder acid containing accelerators, corrosion inhibitors and wetting agents, made to remove rust and water scale from boiler evaporators, heat exchangers, cooling systems and pipeline collection systems. We pack it in 5, 10, 20, 25 and 50 Kg jars.

The second is Safe Acid Descalex Liquid, part number RXSOL-54-1048-025, for cleaning mineral scale from passages in water-cooled or heated equipment. It comes in 25 and 50 Ltr packs.

Liquid acid descaler or descaling powder: which suits your plant

Both remove the same kind of deposit: calcium carbonate scale, rust and other inorganic build-up on the waterside of heat transfer equipment. The choice depends on how you handle, store and dose the product.

The descaling powder is a dry acid. Our record gives a density of 1.2g/cm3 and a pH (10 wt %) of 1.1. It is water-soluble, non-flammable, non-volatile and non-hygroscopic, and contains an anti-foam agent. It needs no heating unless you want it to work faster. Its colour indicator shows the strength of the solution: red when fresh, orange when 85% of the acid has been neutralised, and colourless when it is fully spent. You can top up the circuit with more powder until the red returns. Because you mix it with water on site, you ship acid rather than water, which helps on a long road load.

The acid descaler liquid is ready to dilute and easy to pour into a circulation tank. Typical liquids in this class have a pH below 1.0 and mix with water in all proportions. Our liquid does not need to be heated during cleaning, and our record states it can dissolve approximately 1.5kg of calcium carbonate scale per gallon in concentrated form.

Typical dosage per 100 litres and how to circulate it

For our powder, use a solution of 2.5-10% depending on the extent of scaling. For our liquid, mix with fresh water to form a solution of 10-30%, depending on the extent of scaling. Circulation gives the most effective descaling. Small components can be soaked in an immersion bath. If the equipment is contaminated by oil, grease or sludge, clean it with a degreaser first.

A common starting charge for a heat exchanger circuit is 10 litres of liquid descaler or 5 kg of descaling powder per 100 litres of circuit water. Top up with 5 L or 2.5 kg per 100 L when the pH rises above 2 to 3. Circulate for 1 hour after foaming stops, then flush. Put the inlet at the bottom so air pockets do not form.

In practice, for a cold store chiller holding 400 litres, that starting charge is 20 kg of powder, so one 20 or 25 Kg jar, or 40 litres of liquid, so two 25 Ltr packs. Order a second unit for top-ups if the scale is heavy. Powders in this class are typically heated to about 60°C where possible. Liquid descalers in this class are typically run at about 54°C and kept below about 71°C, because higher temperatures weaken the inhibitor. Most scale clears in 4 to 12 hours, and acid should not stay in the equipment longer than 24 hours.

Metals to protect: stainless, aluminium, galvanised and zinc anodes

Do not use the powder on aluminium, zinc, tin and their alloys, or on galvanised surfaces. Do not use the liquid on aluminium. Many inhibited liquid descalers of this type are also unsuitable for stainless steel and galvanised steel, so tell us your metallurgy before you order. Hydrochloric acid based descalers are not recommended for brazed plate heat exchangers, so confirm the plate and braze metals first. Remove zinc anodes before you start.

Always add acid to water. Hydrogen and carbon dioxide can form during cleaning, so vent the gases outside, allow no hot work during circulation, and gas-test before anyone enters a confined space. Never fire a boiler containing acid. Wear goggles or a splash shield, rubber gloves and a rubber apron.

Neutralising spent acid and storing it in Salalah heat and khareef

After descaling, thoroughly rinse all metal surfaces with a 0.5% neutralising solution in fresh water and circulate it for 2-4 hours or until an acceptable pH value is obtained. This neutralises remaining acidity and passivates steel surfaces. Neutralise spent descaling solution with an alkali to pH 6 to 9 before discharge, or send it to a licensed treatment plant. Follow your site discharge permit, and stop run-off from entering drains.

Khareef humidity and summer heat in open yards are hard on stored chemicals. Keep powder jars sealed and dry, and keep acids out of direct sun. Return part-used containers to shade with lids tight.

Packing, segregation and paperwork for a mixed load

Southern loads often carry raw chemicals beside cleaners. Benzoic acid, part number RXSOL-60-6604-044, is one example. Technical grade benzoic acid is an intermediate for alkyd resins, plasticisers, dyestuffs and preservatives such as sodium benzoate. It is classed with signal word Danger, with H315, H318, H335, H336 and H372. Fine dust in air with an ignition source is a potential dust explosion hazard. Store it cool, dry and ventilated, out of direct sunlight, sealed, and away from food or feedstuffs.

On a mixed load, keep acids segregated from other products, keep labels visible, and check every item against the delivery paperwork at your gate. The MSDS for each product is available on request.

Frequently asked questions

Can a Barka chemical supplier deliver to Salalah port or the Salalah Free Zone?

Yes. We hold stock in our Barka warehouse and deliver to Salalah and Dhofar, including Salalah port, Raysut and the Salalah Free Zone. We confirm the delivery arrangements with your quote.

How much descaler do I need per 100 litres of system water?

A typical heat exchanger starting charge is 10 litres of liquid descaler or 5 kg of descaling powder per 100 litres of circuit water, topped up with 5 L or 2.5 kg per 100 L when the pH rises above 2 to 3. Our powder is used at 2.5-10% and our liquid at 10-30%, depending on the extent of scaling.

What is the difference between a liquid acid descaler and a descaling powder?

Both remove scale and rust. Our powder is a dry acid with a colour indicator that turns from red to orange to colourless as the acid is spent, and you mix it with water on site. Our liquid is ready to dilute, needs no heating, and is supplied in 25 and 50 Ltr packs.

Can acid descaler be used on stainless steel, aluminium or galvanised parts?

Do not use the powder on aluminium, zinc, tin and their alloys, or galvanised surfaces, and do not use the liquid on aluminium. Many inhibited liquid descalers of this type are also unsuitable for stainless steel and galvanised steel, so send us your metallurgy before ordering.

Do you supply an SDS with each chemical?

Yes. The MSDS for each product is available on request. Ask for it with your quote so your site team has it before the product arrives.
