How a Dome Bottom Bypass Feeder Works

A bypass feeder is installed on a dedicated bypass line connected to a closed-loop water system. Water flows through the feeder vessel where treatment chemicals are dissolved and introduced into the circulating water stream. This process allows operators to maintain proper water chemistry while minimizing downtime and simplifying routine maintenance.

For larger HVAC and industrial systems, the DB-18HD provides an efficient solution for supporting corrosion control, scale prevention, and overall water quality management.
