RAPID-DOSE is a disposable pressurised canister, pre-filled with inhibitor, that can be used to dose a sealed system within a matter of minutes.

There’s no need to release system pressure or draw off water. Simply connect the canister to the filling loop isolation valve (or a radiator), using the purpose designed RAPID-DOSE connectors, and the canister will discharge itself.

Rapid-Dose connectors are available to enable dosing via the system filling loop or via a radiator.

Rapid-Dose Central Heating Protector

An advanced formulation for protection against scale, corrosion and bacteria growth in all types of indirect central heating systems, including those containing aluminium. It can add decades to system working life, maintain efficient system operation, and minimise energy use.

Connect directly to a radiator
Add a permanent Rapid-Dose dosing point to a four connector radiator by replacing one of the blank ends with a purpose designed Radiator Dosing Point.
