Corrosion Inhibitor For Closed Circulating System

Corrosion Inhibitor for Closed Circulating System for Water Treatment Chemicals helps to protect metal surfaces in contact with water, wastewater, or process fluids. It is a concentrated liquid product that forms a protective film on the metal surface and protects it from corrosion. The inhibitor can be used in closed circulating systems such as cooling towers, boilers, condensers, and heat exchangers. It is also effective in open systems such as rivers, lakes, and oceans. The inhibitor is available from china in bulk quantities for companies looking to purchase wholesale. It is an environmentally friendly product that does not contain any harmful chemicals or metals. It is safe to use with all types of water treatment chemicals and provides long-term protection against corrosion.

Product Description


This product is used as a corrosion inhibitor for closed systems, such as the cooling water system and hot water circulation system in which glycol, methanol, and ethanol are cooling media. It is composed of organic corrosion inhibitors, dispersants, nitrites, and molybdates to provide reliable protection against corrosion without any chromate-related coloring or staining of surface materials like carbon steel, stainless steel, copper alloy, and aluminum alloy. This product is highly efficient in inhibiting corrosion with convenient usage in the event of no leakage or little leakage from the closed system.

Should be added to a closed system at the rate of 1500 mg/l, with an additional 1.3 times in ordinary operation for optimal performance. When used as a corrosion inhibitor in oil tankers or oil cans, it can be paired with a demulsifier for enhanced effect. Pretreatment filming operation is not necessary when using this product.

Package and Storage:

Should be stored in its original container, away from direct sunlight and extreme temperatures. Do not mix with other chemicals or liquids and ensure that the lid is tightly closed when not in use. It should be handled with care and disposed of responsibly in accordance with local environmental regulations.200L plastic drum, IBC(1000L), customers’ requirement. Storage for ten months in a shady room and dry place.

FAQs about Corrosion Inhibitor for Closed Circulating System:

What are the benefits of using a corrosion inhibitor for closed circulating systems?
A corrosion inhibitor for closed circulating systems helps to protect metal surfaces from damage caused by acidic and alkaline chemicals. It can also help reduce or eliminate the formation of rust, sludge, and scale deposits in pipes, boilers, and other equipment components. This can improve system efficiency, reduce downtime due to maintenance, and extend the useful life of piping and equipment.

How does a corrosion inhibitor work?
Corrosion inhibitors form a protective layer on metal surfaces, preventing them from coming into contact with corrosive chemicals in the water treatment system. The molecules of the inhibitor attach themselves to the metal surface, forming an invisible barrier that protects against chemical attack. The exact mechanism depends on the type of inhibitor used – some work by providing a physical barrier between the metal and water, while others form chemical compounds which react with and neutralize corrosive substances in contact with the metal surface.

What kinds of corrosion inhibitors are there?
The most commonly used types of corrosion inhibitors include organic acids (such as benzoic acid), phosphates (such as sodium phosphate), and polymers (such as polyphosphates). There are also proprietary mixtures that combine several types of inhibitors into one product. These mixtures provide enhanced protection compared to single-component products but may vary considerably depending on their formulation.

How do I select an appropriate corrosion inhibitor?
When selecting a suitable corrosion inhibitor, it is important to consider its compatibility with other chemicals used in the system, as well as its performance under different conditions such as pH levels and temperature ranges – some inhibitors are effective only in certain environments or for specific metals. Also, take into account any regulatory requirements since some inhibitors may not be allowed in certain areas or applications due to environmental considerations or health concerns.
