| Bello Zon ClO2 systems | Bello Zon chlorine dioxide family (CDLb-CDKd), 0-120 g/h up to 12,000 g/h, named for industrial cooling tower water treatment | ProMinent — Water Treatment and Disinfection Systems |
| CHLORINSITU on-site generation | CHLORINSITU III/V/V Plus on-site hypochlorite generation, 100-10,000 g/h chlorine, named for cooling tower service | ProMinent — Water Treatment and Disinfection Systems |
Becker's own design guidance: almost every chemical feed system — cooling tower dosing included — is built around pH and conductivity probes, with the specific chemical determining probe count and type rather than a standard sensor package.
Cooling tower dosing is a continuous-cycle problem, not a one-time dose — ProMinent's Bello Zon and CHLORINSITU lines exist because on-site chlorine dioxide or hypochlorite generation removes the hazardous-chemical transport and storage risk a trucked-in dosing chemical carries on a recirculating tower loop.
