Star One Shot BTW is a liquid blend of alkaline compounds, scale and corrosion inhibitors, oxygen scavengers and sludge conditioners. The alkalinity balance is extremely important for efficient water treatment. Star One Shot BWT provides this whilst avoiding excessive pH levels which could cause embrittlement and corrosion of boiler components.

Hardness Control: Star One Shot BWT provides a phosphate reserve to effectively react with and precipitate the hardness salts introduced with the feed water. The formation of insulating scale on hot metal surfaces is prevented as the salts produced will not adhere and so optimum heat transfer efficiency is maintained. The stable phosphate compounds used in One Shot BWT will maintain their efficiency throughout the boilers normal operating temperature range. Where low temperatures can cause low phosphate levels, this is avoided.
Sludge Conditioning: Boiler sludge can most easily be removed by blow down if it is free flowing. Star One Shot BWT will ensure this by preventing the scale from coalescing to form large crystals or adhering to metal surfaces. The resulting sludge is free flowing & will easily be removed by blow down when required.
Oxygen Control: Oxygen scavenging becomes more vital with an increase in boiler pressure. The oxygen scavenger will effectively react with dissolved oxygen even at lower temperatures.
Star One Shot BWT is best fed into the boiler feed line by means of a metering pump. Gravity fed systems should be dosed by means of a flowmeter and dosing drum.
Do not slug dose
Initial Dose: Untreated System 5 litres / 1000 litres distilled feed water resulting in 100ppm P. Alkalinity.
Additional dosing of Star ONE SHOT BWT is required to bring the P.Alkalinity level to a mid point of 200ppm. Blow down is dependant on Alkalinity & Chloride levels. If alkalinity drops below 100ppm, increase the dosage by 20%, if alkalinity exceeds 200ppm, reduce dose by 20%.
In general the ranges are:- 100-300ppm ppm P Alkalinity 200ppm Chloride maximum.
