Automatic Chemical Feeder for Cooling Water Systems with Anti-Corrosion Coating
Industrial automatic chemical dosing unit for cooling water and recirculating water systems. Buyer checks should focus on dosing capacity, tank volume, pump type, voltage, wetted-material compatibility, coating specification, control configuration, export packing, and document availability. This is equipment for chemical dosing, not a standalone cooling water treatment chemical.
