The feed is ideal for treating hot and chilled closed water recirculation loops use din heating and air conditioning systems, process heating and cooling or large engine water jackets.

The By-Pass Feeder includes a high-pressure cap rated to 300 PSI (20.7 bar) as a standard. The caps are designed for quick-opening, high-pressure closure for better sealing with less force, and eliminate the need for tools. The design binds the cap tightly when under pressure, making it necessary to bleed pressure from the tank before removing.
