Description
Anglo Gulf Aqua AG 351/359, a cooling tower biocide range made by Anglo Gulf FZE, gives you two biocide chemistries, isothiazolinone (AG 351) and quaternary ammonium (AG 359), for algae and bacteria control. UV Water Systems supplies this cooling tower biocide across Oman with technical advice, dosing equipment and site support.

Anglo Gulf FZE is based in Jebel Ali Free Zone, Dubai. The company runs a formulation plant with its own laboratory, can produce and pack up to 60,000 litres per day, and has manufactured chemicals for the oil and gas and process industries since 1998.
Why Choose This Cooling Tower Biocide in Oman?
Warm water, sunlight and dust make Oman cooling towers an easy place for algae, slime and bacteria to grow. Biofilm reduces heat transfer and can harbour Legionella. Alternating two different biocides is a common way to keep control over time.

Sizing, Dosing and Service
Biocides are usually slug dosed on a set schedule. We work out the volume and frequency from the system size and the results of bacteria dip-slide tests. We do not publish fixed dose rates, because the correct dose depends on your water and system. Always handle chemicals with gloves and eye protection and follow the product SDS.
