Types of Chiller Chemicals

What are Chiller Chemicals used for?
Chiller Chemicals are used to minimize corrosion to closed loop water systems. It primary purpose is the removal of the corrosive substance by the means of passivation, precipitation, or adsorption. Passivation works best for laboratory chillers, industrial chillers, process chillers and for other closed loop systems. Passivation inhibitors form a protective oxide film on the metal surfaces. Their protective films are tenacious and will rapidly repair itself if damaged. Please refer to our Closed Loop Chemical Chiller Guide for more information.

What Chiller Chemical do I use for our closed-loop water system?
The most common and most cost-effective closed loop chemical used to passivate your water system is a Nitrite, Borate, and Silicate closed loop chemical. For very critical closed loop systems, a straight molybdate product is used to control corrosion.

How much chemical do I feed to my closed loop water system?
Ask what the feedrate ppm (parts per million rate) is of the chemical.

How do I add the chemical to the system?
For closed loop water system, the product is typically added to an industrial pot feeder.

How long will the chiller chemical last before it needs to be replaced?
7 to 10 years. Nitrite takes many years to convert to Nitrate. Once the product has converted to Nitrate it is no longer provides proper passivation.

What water treatment tests need to be performed?
Monitor the water conductivity and nitrite residuals. For closed loop water systems, 800 to 1200 ppm of nitrite residual must be continuously maintained.

We have two popular closed loop corrosion inhibitors:

ChemWorld 2338 / 2338D - The difference between Chemworld 2238 and Chemworld 2338D, is the "D" product has a P Indicator for ease of detection.
Chemworld 811 - Is designed for food regulated facilities or water systems where incidental food contact may occur. Chemworld 811 is also approved for use in food grade glycol water systems.
ChemWorld SM35 - Is a popular product for critical chilled loop closed loop systems or where the closed loop temperatures are above 45F and ongoing bacteria problems exist. Sodium Molybdate is a more expensive choice for controlling corrosion within your water system.
