AMERSITE CHZ is an all-volatile, liquid oxygen scavenger and corrosion inhibitor for use in low-, medium-, and high-pressure steam generating systems. AMERSITE CHZ controls ferrous and non-ferrous corrosion in feedwater, boilers, steam and condensate lines with the use of carbohydrazide as the oxygen scavenger. In addition to scavenging oxygen, AMERSITE CHZ passivates metal surfaces through the formation of a protective oxide film.

AMERSITE CHZ corrosion inhibitor may be used with DREWPLEX® AT boiler water treatment, standard treatment for low-pressure steam generating systems (0-32 bar), standard treatment for medium-pressure steam propulsion
vessels (32-60 bar), and our ULTRAMARINE℠ boiler water treatment program for high-pressure steam generating systems (60-84 bar)
APPLICATION & USE
The continuous dosage of AMERSITE CHZ depends on the amount of dissolved oxygen in the feedwater. The colder the feedwater, the more dissolved oxygen there will be. Keep the feedwater temperature as close to 90 °C, or higher, if possible. For starting up a new system, an estimated initial dosage of AMERSITE CHZ is 0.45 liters per ton of boiler water in the system. Daily testing of AMERSITE CHZ in the boiler water using the AMERSITE CHZ test kit (Pen # 1AB2690) determines the necessary dosage to maintain the concentration within the specified control range. If the system has been poorly passivated, the initial system “demand” for AMERSITE CHZ may require a higher dosage for the first few weeks until the system comes to stabilization.
