These units are built as two tandem identical sections, with the process pumps feeding concurrently two arrays of venturi ejectors, each one followed by a dynamic mist separator. This modularity allow the simultaneous neutralization of gases either acid and alkaline, like for house scrubbers in elettronics fabs or the two-stages deodorization in food and stock-farming (meat meals, poultry etc. ). the installed instrumentation, depending on final application, comprises 1 or 2 ph or redox along with chemical reagents dosing pumps; the gas flowrate and pressure in the suction areas are controlled in real time by varying the fan speed. Available in pvc and pp with flowrates from 15,000 to 170,000 cmh, feature a monolythic construction upto 50,000 cmh for ease of transport and installation.
