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.
