Neptune FTF-5DB Filter Feeders

By-Pass and Filter Feeders

Neptune By-Pass Feeders are a convenient method of introducing treatment chemicals into closed water recirculation systems. Neptune By-Pass Feeders are ideal for treating hot and chilled closed water recirculation 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 cleanup and monitoring. All By-Pass Feeders feature a high-pressure cap rated to 300 psi (20.7 bar) as a standard. The By-Pass Feeder caps are designed for quick-opening, high-pressure closure for better sealing with less force and eliminates the need for tools. Design binds cap tightly when under pressure, making it necessary to bleed pressure from tank before removing.

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 closed water recirculation systems.

FAQ

• What is the purpose of the Neptune FTF-5DB Filter Feeder?

Neptune FTF-5DB Filter Feeder is designed to introduce water treatment chemicals into closed-loop recirculating systems. It combines chemical dosing and high-capacity filtration in a single unit to improve system reliability and cleanliness.

• Where is the FTF-5DB filter feeder typically used?

It is commonly used in HVAC heating and chilled water loops, boiler systems, process cooling circuits, and engine jacket water systems where closed-loop water quality must be maintained through chemical treatment and debris removal.

• How does the filter feeder work?

Water is diverted through the feeder via a bypass line, where treatment chemicals dissolve and mix into the system. At the same time, an internal stainless-steel basket holds a filter bag that captures contaminants before the water returns to the loop.

• What filtration options are available for the FTF-5DB?

The unit supports replaceable ring-top filter bags available in 1, 5, 20, and 50 micron ratings, allowing operators to select filtration levels based on system cleanliness and startup or maintenance requirements.

• What are the operating pressure and temperature limits?

The Neptune FTF-5DB is engineered for industrial environments and is rated for operation up to 300 PSI (20.7 bar) pressure and 200°F (93°C) temperature, making it suitable for demanding closed-loop applications.
