Neptune By-Pass Feeders are a convenient method of introducing treatment chemicals into closed circulating water systems. Neptune By-Pass Feeders are ideal for treating hot and chilled water circulating loops used in heating and air conditioning systems, process heating and cooling or large engine water jackets. Neptune offers two styles of By-Pass Feeders: A vertical style with dish bottom in and a vertical style with dish bottom out. Filters are available for system cleanup and monitoring.

The Neptune Filter Feeder combines chemical addition and high capacity filtering in one piece of equipment. It is a convenient way to introduce solid or liquid chemicals into hot or cold water closed circulating systems.
