ADC 377

Dumping Investigation ADC 377 - Cooling Tower Water Treatment Controllers exported from the United States of America.

Goods Covered by the Investigation


The goods the subject of the application (the goods) are:

Industrial water treatment controllers, programmed to monitor and/or treat water in a cooling tower, with or without accessories including sensors, pumps, solenoids and modem (cooling tower water treatment controllers).

Further information on the goods:

A cooling tower is a heat rejection device that rejects waste heat to the atmosphere through the cooling of a water stream. Common applications of cooling towers include air conditioning for buildings and the cooling of circulating water in industrial processes.

Cooling tower water treatment controllers are units programmed to monitor water conditions (such as conductivity, Oxidation Reduction Potential (ORP) and power of hydrogen (pH) levels) in the cooling tower water and/or initiate actions required to bring the water to within the user’s desired parameters (for example, through the addition of disinfecting chemicals). A controller typically comprises a printed circuit board or boards (PCBs), connection terminals, a display screen and control panel with keypad.

The control functions of cooling tower water treatment controllers are based on inputs from probes measuring the properties of the water.

Depending on the reading from the probes, the unit signals ancillary devices such as a bleed solenoid, a feeder and/or pump/s (which are connected to the water treatment system separately as an additional system component) to drain a controlled amount of water or dose the water with the required amount of chemical(s) (for example, oxidising biocide, acid).

In addition, the goods are often equipped with internal timers which are programmed by users to send signals to ancillary devices to dose water with other chemicals when required (for example, inhibitor secondary biocide (non-oxidising), dispersant).
