RXSOL Boiler Water Treatment – AUTOTREAT
Product Name: Boiler Water Treatment AUTOTREAT
Brand: RXSOL
Product Category: Marine & Industrial Boiler Water Treatment Chemicals
Product Description
RXSOL AUTOTREAT is a multipurpose boiler water treatment chemical designed for the treatment and conditioning of boiler water in marine and industrial steam-generating systems.
It is intended to provide combined protection against scale formation, corrosion and sludge accumulation, helping maintain boiler efficiency, improve heat transfer and reduce maintenance requirements.
A properly formulated AUTOTREAT product can combine alkalinity control, hardness conditioning and sludge dispersion in a single liquid treatment.
Autotreat is a boiler water conditioner designed for optimum protection of ships boiler systems when used in conjunction with Oxygen Scavenger Plus. The product combines well known phosphate treatment with new polymer technology. This ensures that precipitates are kept soft and no adherent for easy removal by blow down. The product should always be used in conjunction with an oxygen scavenger, preferably Rxsol Oxygen Scavenger Plus. Note that this product is formulated for use in conjunction with good quality feed water.
Application
Key Features and Benefits
-
Scale Prevention: Helps prevent calcium and magnesium hardness deposits on boiler heating surfaces.
-
Corrosion Control: Maintains suitable alkaline conditions to minimize corrosion of boiler internal surfaces.
-
Sludge Conditioning: Converts residual hardness into manageable sludge that can be removed through blowdown.
-
Heat Transfer Efficiency: Reduces insulating deposits and associated energy losses.
-
Multipurpose Treatment: Combines several boiler water conditioning functions in one product.
-
Easy Dosing: Suitable for controlled dosing through a chemical dosing pump.

The product should preferably be dosed continuously with a Rxsol Boiler Water Treatment Dosing Unit. Alternatively the product can be fed into the feed line by means of a by-pass pot feeder.
Dosage and control
Minimum dosage is 1.2 liters of Autotreat/ton of boiler capacity to reach a P-Alkalinity level of 100 ppm. For an untreated system it is recommended to initially bring the treatment up to a suitable level of 200 ppm p-Alkalinity. The dosage chart given below is for convenience to determine the amount of product required to elevate P-Alkalinity. Note that the table is based on reaching 200 ppm. P-Alkalinity.
Sampling and testing
A representative sample of boiler water should be drawn for analysis daily. The sample should always be taken from the same point after blow down, cooled and tested immediately. Follow the Spectrapak Test Kit instructions and log the results. It is important that regular testing is carried out to ensure that treatment levels are correct.
