STEAM BOILER TREATMENT PRODUCTS

General Information: Steam boiler treatment includes chemical materials which prevent deposits, scavenger oxygen, reduce corrosion, and under proper conditions gradually clean treated boilers. The products can be provided as individual components for maximum flexibility in the program, or as combined formulations for ease of handling. WTW products represent common and accepted components and formulations.

CONDENSATE RETURN LINE PRODUCTS

General Information: Neutralizing amines can reduce return line corrosion which is characterized by grooving and thinning pipe walls. WTW return line products are formulated based on:

	Ability to travel with the steam
	Ability to condense at the correct points in the system
	Ability to be retained in the system

RL-23 Return Line Treatment  is a multi-component formulation designed to treat a variety of return line conditions while remaining within USDA dosage parameters. This product is USDA G6 approved.
RL-24 Return Line Treatment  is designed for high steam pressures and long steam line runs, either or both. Formulated for medium sized applications . This product is USDA G6 approved.
RL-25 Return Line Treatment  is designed for low steam pressures and long steam line runs. Formulated for medium-to-large sized applications. USDA G6 approved.
RL-26 Return Line Treatment  is designed for high steam pressures and short steam line runs, either or both. Formulated for medium sized applications, USDA G6 approved.
RL-27 Return Line Treatment  is designed for medium steam pressures and medium steam line runs, either or both. Formulated for medium sized applications, USDA G6 approved.
RL-28 Return Line Treatment  is a multi-component formulation designed to treat a variety of return line conditions while remaining within USDA dosage parameters. Formulated for large applications, USDA G6 approved.
RL-29 Return Line Treatment  is designed for high steam pressure in large applications. This product is USDA G6 approved.
RL-30 Return Line Treatment  is designed for low steam pressures and long steam line runs, either or both. Formulated for large applications, USDA G6 approved.
RL-31 Return Line Treatment  is designed for high steam pressures and short steam line runs, either or both. Formulated for large applications, USDA G6 approved.
RL-32 Return Line Treatment  is designed for medium steam pressures and medium steam line runs, either or both. Formulated for large applications, USDA G6 approved.
RL-51 Return Line Treatment is an ammonia based steam line return treatment, specifically designed to provide corrosion protection in dairy product and related food processing plants.

COOLING TOWER SCALE AND CORROSION CONTROL

General Information: Although the name "cooling tower treatment" is familiar, we could better call these products "heat exchanger treatment." WTW products are formulated to provide scale and corrosion control in a wide range of field conditions and especially at the heat exchange area where efficiency is gained or lost. WTW cooling tower products are formulated based on:

	Safety for personnel and systems
	Dischargeability
	Broad range of field conditions

CW-6 Scale and Corrosion Inhibitor  is designed for systems using makeup water of moderate hardness and alkalinity, and discharging to a city sewer or other treatment plant. It is controlled by a molybdate test which provides easy and accurate control readings. This product is USDA G7.
CW-7 Scale and Corrosion Inhibitor  is designed for systems using makeup water of high hardness and alkalinity and discharging to a city sewer or other water treatment plant. It is controlled by a molybdate test which provides easy and accurate control readings. This product is USDA G7.
CW-8 Scale and Corrosion Inhibitor  is designed for systems using makeup water of moderate hardness and alkalinity. Formulated with no metals or orthophosphates, this product meets typical sewer discharge parameters and all but the most stringent direct outfall parameters. It is controlled by an Organo Phosphonate test or fed volumetrically. This product is USDA G7.
CW-9 Scale and Corrosion Inhibitor  is designed for systems using makeup water of high hardness and alkalinity. Formulated with no metals or orthophosphates, this product meets typical sewer discharge parameters and all but the most stringent direct outfall parameters. It is controlled by an Organo Phosphonate test, or fed volumetrically. This product is USDA G7.
CW-38 New System Scale and Corrosion Inhibitor  is designed for start up operation of cooling systems where a new galvanized metal cooling tower is being placed into service. This product meets typical sewer discharge parameters and all but the most stringent direct outfall parameters. It is controlled by a molybdate test which provides easy and accurate control readings. CW-38 can also be used to provide scale and corrosion inhibition on an ongoing basis in systems where the makeup water hardness and alkalinity vary widely, including soft water makeup.
WTW can assist you in selecting a cooling tower inhibitor based on your answers to a few simple questions about your system. All cooling tower inhibitors should be fed by an automated control system to accurately maintain correct feed and bleed rates.  Click here for a

CLOSED LOOP TREATMENT

General information: WTW Closed loop treatment products are suitable for corrosion control in hot, cold, or temperate closed loop systems not containing glycol. The products are formulated to incorporate:

CL-4 Closed Loop Treatment  is a familiar and often used Nitrite based inhibitor formulation. This formulation is especially well suited for hot water boiler or chilled water applications.
CL-5 Closed Loop Treatment  incorporates Molybdate into a multi-component formulation, providing excellent corrosion inhibition and passivation properties. This formulations is suitable for recirculating loops which are open to the atmosphere as well as closed loops.
CL-36 Closed Loop Treatment  is a sulfite based formulation recommended in systems where biological control could be a problem if a nutrient based inhibitor was used. It is most commonly used in temperate loops, such as heat pumps.
CL-39 Closed Loop Treatment  is a dry Nitrite based inhibitor formulation.  This formulation is well suited for both hot water and chilled water applications.  CL-39 dry Nitrite is only available in 300 pound 55 gallon drums.
In the absence of any specific system problems, continue with whatever type of treatment matches the current program. New or contaminated systems should be flushed prior to treatment. WTW can assist you in selecting the appropriate closed loop treatment product based on your answers to a few questions about your system.  Click here for a
