The Sentinel Dosing Vessel is specially designed for dosing the Sentinel range of heating system additives and conditioners directly into the central heating circuit, either by injecting through a coombination boiler's filling loop, or any other convenient point such as a radiator air vent. The dosing rate is fully controllable by adjusting the ball valve, and pressure is maintained during dosing by a few pump strokes at infrequent intervals.
