WTP Ultrabrom 30 is a liquid biocide often described as a stabilised blend of Hypochlorite and bromide salts. It is used to control bacteria and other organisms in recirculating cooling water, pasteurisers, air washers and other heat transfer systems. It also works well in all systems where contamination has limited the effectiveness of other oxidising biocides.

WTP Ultrabrom 30 is effective at pH values of up to 8.8 and is therefore more effective than chlorine and hypochlorite.


Physical State Yellow liquid
Specific Gravity 1.30-1.35
pH 13.1-13.4


WTP ULTRABROM 30 is dosed to Evaporative Cooling Systems to maintain a reserve of 1.0 to 2.0 ppm of free halogen.(a requirement of HSE L8).

Applications can vary but an effective application is for continuous dosage.

WTP ULTRABROM 30 is best applied using a suitable dosing pump to an area of good mixing. Redox Control Modules are also recommended for accurate automatic dosing.

Control at 0.5 ppm to 1 ppm total halogen, as chlorine (x 2.2 = Br), if fed continuously. Recirculation rate (m3/hour) x 0.0088 = kg day


A Chlorine test kit is available to determine correct reserves in the system (WTP TK115) or a Bromine test kit (WTP TK127).


Use biocides safely. Always read the label and product information before use. Our Technical Personnel will advise the most effective dosing method for each application. HANDLING AND STORAGE Please refer to material safety data sheet for detailed handling/storage instructions.
