Chemtex Speciality Limited

Cooling Water Dispersants Chemical remove depositions from fins, louvers and pipelines during normal servicing. It is a neutral pH product and does not cause any corrosion to the system metal during use. It can be dosed manually to the cooling tower pump daily or continuously with a dosing pump. It works using a combination of chelation, crystal modification and threshold effect, and is effective against a wide range of scalants including calcium and magnesium hardness, iron oxide and silica. It converts the scaling material into a light mobile floc, that can be blown down easily.

Key Features and Benefits:

• Neutral pH product
• Dosed manually or automatically
• Wide scale application
• Known for maintenance clean up programs

• No disposal problem (contains no chromate, zinc or heavy metal)
• Effective over a wide pH and temperature range

Chemtex’s Cooling Tower Antiscalant And Corrosion Inhibitor is a highly effective blend designed to control scale, corrosion, and non-biological fouling in cooling water systems. It does not contain chromate, zinc, or heavy metals. It is designed for the prevention of hardness deposition in recirculating or once through cooling systems using moderate to high hardness make-up water. It provides corrosion protection to system metallurgy under a variety of conditions.

Chemtex’s Cooling Tower Antiscalant And Corrosion Inhibitor is purely organic and biodegradable, thus does not promote heavy metal discharge in blow down.

Key Features and Benefits

Nitrite Based Corrosion Inhibitor is a superior blend of multi-metal corrosion inhibitors for closed-loop systems containing chiller or hot water. It prevents corrosion or rusting of metal by forming a passive coating of protective oxide film on steel. Chemtex's Nitrite Based Corrosion Inhibitor prevents scaling and deposition of calcium and magnesium hardness and iron deposits. Thus keeping the heat exchange at the best efficiency.

Key Features & Benefits:

• Multi-metal corrosion protection
• Saves power more than 30%
• Non-foaming
• Enhances cooling efficiency
• Added oxygen scavenger
• Leakage and burst protection
• Extends system life
• Extends fluid or glycol life
• No descaling of Heat exchangers

Chemtex's Molybdate Based Corrosion Inhibitor has been specifically formulated for use in closed loop system containing chiller or hot water. It prevents corrosion or rusting of metal by forming a passive coating of protective film over ferrous metals and non-ferrous metals.

Application Areas:
CHW line of HVAC, Glycol Chillers, Secondary Cooling Water Systems, Blast Furnaces, Mold Cooling Systems, Casting Mills, Hot & Cold Water System

Chemtex's High pH Silica Antiscalant is a chemical compound that is useful for preventing silica fouling in the RO membrane. The silica antiscalant is a alkaline product and is very much suitable for being added to drinking water system.

Polymer Dispersant removes the silt deposits from the fins, and pipelines during normal service. It is a polymer and surfactant-based product that breaks the clay deposits and removes them with blowdown water. It is a neutral pH product and does not cause any corrosion to the system metal during use. It can be dosed manually to the cooling tower sump on a daily basis or can be dosed continuously with a dosing pump. It works using a combination of chelation, crystal modification, and the threshold effect, and is effective against a wide range of scalings including calcium and magnesium hardness, iron oxide, and silica. It converts the scaling material into a light mobile floc, which can be blown down easily. It will gradually re-disperse old deposits and may be used as part of maintenance ’clean up’ program.

Key Features and Benefits

• Keeps the cooling tower internals pipelines and louvers clean
• Provides high efficiency to the cooling towers working in high dusty area
• Neutral pH product, biodegradable
• Compatible with other chemicals and all metallurgy
