The easy and efficient way to administer Sentinel treatments.

Tackle the problems of boiler noise, scale, corrosion and sludge at source by directly injecting the heating circuit.

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 combination 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.

• Compact and Robust
• Fully adjustable output
• Corrosion resistant construction
• Integral pumping system
• Tapered nozzles supplied will fit most radiator vents
• Supplied complete with boiler fill loop adapter
