Chemical Dosing

Our range of chemical dosing pots allow the safe dosing of chemicals into closed systems with no interruption of operation.

Chemical Dosing Pots

The Dutypoint range of dosing pots provides a safe, controlled method of dosing chemicals into heating and chilled water systems with no interruption to the system operation.

Dutypoint dosing pots are supplied as a complete package with all valves and tundish fitted to minimise time on site for installation. These cost effective, easy to install units facilitate simple, regular on-going maintenance of your heating or chilled water system. Dutypoint chemical dosing pots feature a top-mounted, manual air vent that can be opened during the filling operation to minimise air ingress into the system.

For your safety, each Dutypoint chemical dosing pot is fitted with an integral safety valve that prevents fluid escaping under pressure if the top entry valve is opened before the flow and return valves are closed. Also, for your peace of mind, each unit is individually hydrostatically tested to 16 bar prior to despatch.
