Copper Corrosion Inhibitors

A corrosion inhibitor is a substance that prevents or retards the corrosion rate of boiler metals or alloys when added to its surface or surrounding environment. Its efficiency is determined by several factors including but not limited to: fluid composition, water quantity, and flow regime. A high efficiency (90%-99%) is guaranteed if the correct inhibitor and quantity are chosen.

Depending in its chemical composition, a corrosion inhibitor works in several ways. One of which is through passivation, or the formation of a thin film on the surface of a material. It inhibits contact of the corrosive substance, thus, preventing either oxidation or reduction. For materials that are already corroding, an inhibitor can act by either adsorption, which is molecular adhesion on the surface of a metal, or scavenging, which is inactivation of the dissolved oxygen.

 A corrosion inhibitor is just one of the several chemicals necessary boiler system maintenance. For closed- and open-looped stoves with minimal water loss, a boiler chemical composed of a highly concentrated liquid buffered nitrite, borate, and silicate inhibitor is suitable. Corrosion inhibitor is available through ChemWorld as CLC 830. It is designed to protect all common metals in woodstoves, which includes stainless steel, copper, and aluminum. Product is suitable for both hot and cold systems, and is compatible with glycol-based heat transfer fluids. 

Features and Benefits:

One gallon can treat approximately 500 gallons of make-up water and can be used with either hard or soft water. CLC 830 can be shot fed to the system and is dyed in pink for ease of proper dosage detection. Product has met all D.O.T. shipping regulations.

Product Feed and Control:

CLC 830 is shot fed directly from the shipping container. Feeders, piping, and valves should be made of steel, polyethylene, or PVC. Treatment control ranges vary depending on system operating conditions. Product is controlled by a nitrite test and should be handled by a technical specialist who will provide specific treatment control levels.

Storage and Handling:

Keep product in a tightly closed container. Store in a room with a temperature range of 10° - 40°C (50°-100°F) and keep product away from direct sunlight. Do not reuse empty container but dispose empty it in compliance with existing federal laws.



Featured Products:

Same day shipping on all containers and drums if ordered by 3pm EST.
