Cyclone scrubber for fertiliser company

Project Date




Fertiliser Plants

Ducting, Wet Cyclone, Fans, Stack


The fertiliser company needed to improve the working conditions within its manufacturing building, by extracting air laden with both dust and fluoride fumes. At the same time they wanted to have just one stack discharging to atmosphere, and the discharge from this had to meet their Resource Consent limits.


Armatec designed, manufactured, and installed a hygiene scrubbing system including a wet cyclone scrubber, fan, ducting, and stack. This was done as part of the overall upgrade of the plant’s scrubbing system, with the hygiene system linking into the main scrubber stack.


Fluoride and dust levels in the manufacturing building were much reduced, improving working conditions for plant personnel, at the same time meeting all Resource Consent limits.
