Chemical Pot Feeder
Chemical Pot Feeders / By-pass Feeder for Closed-Loop Chilled Water Treatment
A chemical pot feeder / by-pass feeder is an essential, highly reliable component in the maintenance of closed-loop HVAC systems, engineered specifically for the precise manual dosing of specialized water treatment chemicals. This industrial bypass dosing device facilitates the safe, controlled introduction of chemical formulations into the main fluid stream, ensuring the proper thermodynamic balance and maximum effectiveness of your water treatment processes. Engineered as a robust, ASME-rated pressurized steel vessel, the pot feeder for chilled water networks is strategically installed parallel to primary recirculating pumps, leveraging natural pressure differentials to drive efficient, inline chemical distribution without requiring a dedicated injection pump.
To accommodate different system volumes and mechanical footprints, chemical bypass pot feeders are manufactured in various capacities—including 2, 5, and 10 gallons. Each unit is equipped with a wide-mouth filling funnel, isolator ball valves, a drain line, and an integrated air vent valve to completely simplify and secure the manual chemical addition process for facility technicians. These rugged dosing systems seamlessly accommodate a comprehensive range of water chemistry treatments, including corrosion-inhibiting nitrite-based chemical treatments often paired with azole or molybdate passivating additives, as well as high-potency non-oxidizing and non-foaming biocides. Implementing a premium manual pot feeder system is vital for preventing internal biological fouling, mitigating pitting corrosion, and sustaining optimal heat transfer efficiency across commercial and industrial chilled water networks in Dubai.
At Dubai Water Treatment, we supply, integrate, and service heavy-duty by-pass feeders tailored to withstand the high-stress demands of the UAE’s commercial cooling sector. Our technical engineering teams ensure that your dosing infrastructure is calibrated to distribute inhibitors uniformly across your entire evaporator circuit, protecting your central chiller barrels from early breakdown, maintaining strict compliance with local building guidelines, and driving down long-term operational expenditures (OPEX).
