WATER TREATMENT

QUALITY CHEMECALS WITH EXCELLENT PERFORMANCE

Apex Chemecal team’s expertise, experience and strong product and industry knowledge enable us to provide a wide range of value-added services. Our customers benefit from numerous cost-effective solutions provided by the company.

Apex Chemicals has been ISO-certified for more than 17 years. The company has also attained NSF approvals and the prestigious IMO approvals for tank cleaning chemicals.

WATER TREATMENT

We offer a complete range of chemicals for fuel oil treatment, Boilers, Heaters, Scale, rust removal, corrosion treatment, water treatment, cleaning and testing.

Water treatment chemicals are essential for a safe and effective operation. Corrosion, Scale, Sludge, Bacteria and Fouling are some factors that will result in breakdown, costly repairs, loss of power, waste of energy and money.

We share IMO’s focus on a green, sustainable development to ensure that the industry remains safe, environmentally sound, secure and energy efficient.

CHEMICALS

We supply a complete range of water treatment chemicals for all your vessel requirements.

AWT-11 Alkalinity Compound is an inorganic and non-volatile alkali for use in both high and low-pressure boilers. It inhibits corrosion and assists in the conversion of hardened precipitates into soft and non-adherent sludge. Alkaline pH-Controller can also be used as a neutralizing agent after descaling with acidic chemicals.

AWT-13 Dispersant is a specially formulated chemical used to prevent suspended solids from adhering to internal boiler surfaces and for on-line removal of existing scale of sludge deposits.

AWT-17 Combotreat BWT is a liquid “One-shot Treatment” for rust and scale control in LOW pressure and exhaust boilers with working pressure up to 28 bars.

AWT-18 Combotreat BWT/HP is a synergistic blend of scale inhibitors, strong alkalis and special polymeric dispersant in a single formulation. AWT-18 can be used in high-pressure boilers up to 1000psig. The ingredient in AWT-18 meets the FDA Section 173.310 Boiler Water Additives.

AWT-20 Hardness Controller is a white powder, phosphate base boiler compound. It is specially formulated to prevent and remove scale deposits and incrustation in boilers of any service pressure.

AWT-30 Condensate Controller is an organic, volatile alkalization agent for medium and high-pressure boiler systems.

AWT-45 Oxytreat is an oxygen scavenger. It minimizes oxygen corrosion and prevents the formation of red oxide on interior boiler surfaces. It controls iron and copper oxidation arising from steam condensate and feed-system.

AWT-375 Microbiocide is a highly effective biocide and bactericide for use in controlling the growth of shellfish, algae, fungi and micro-organisms found in sea water systems

AWT-390 Corrosion & Scale Inhibitor is a combination of polyphosphates. It is quickly and easily soluble in water. AWT-390 is specially formulated for corrosion and scale prevention in boiler & industrial water systems, marine equipment, condensers, coolers, heaters, tanks, pipelines and potable water systems.

AWT-390L Potable Water Stabilizer is a solution of polyphosphates, quickly and easily dispersible in water. AWT-390L is specially formulated for potable water systems, corrosion and scale prevention in boiler & industrial water systems, marine equipment, condensers, coolers, heaters, tanks and pipelines.

AWT-425 Anti-Freeze Compound is an inhibited liquid designed as an effective anti-freeze compound. It contains selected inhibitors, capable of protecting cooling systems of all types, water-cooled internal combustion engines and radiators.

AWT-426 Liquidtreat DCWT is a modern and comprehensive blend of Nitrite and Borax Constituents, designed to provide total corrosion and deposition control in closed water systems of mobile or static diesel and petrol engines. It forms a protective inhibited film which protects the metallic surfaces of the cooling systems against corrosive attack, keeping the engines clean and free from overheating.

AWT-427 DCWT Powder is a modern and comprehensive blend of Nitrite and Borate constituents. It is designed to provide total corrosion and deposition control in closed water systems of mobile or static diesel and petrol engines. It forms a protective and inhibited film, protecting the metallic surfaces of the cooling systems against corrosive attack. This keeps the engines clean and free from overheating.

AWT-433 Preclean is designed for the removal of oil, grease, loose rust and other foreign materials, from newly constructed boiler and cooling systems or badly fouled water systems.

AWT-440 Evaporator Treatment is formulated for use in marine evaporators to prevent scale formations. AWT-440 is a polymer-based liquid additive, containing sodium polyacrylate, dispersant and defoaming agents.
