Chemical Dosing Pots

Chemical Dosing Pots - 3.5 to 25 Litres

Though they are not particularly well-known outside of the trade, chemical dosing pots are certainly familiar to those who work in plumbing. Chemical dosing pots are used to safely and accurately feed liquid chemicals, such as those designed to inhibit corrosion, into a closed system. A chemical dosing pot provides an instant and reliable solution. Consisting of a stainless steel vessel, with four valves (return, flow, drain and filling), and a stainless steel tundish which itself has an air-release and a non-return valve, the dosing pots allow for chilled or hot water systems to be dosed with the relevant chemical, protecting the system and improving its functionality and service life.

Wall-mounting brackets are provided for your convenience.

In operation, the dosing pot is fitted across the return and flow lines, effectively annexing a portion of the system’s water, which is drained away and replaced with the chemical, keeping the system balanced. The system is reconnected and the chemical can flush throughout, carrying out its particular role.

Each pot is fitted with a large (1”) valve to ensure the pot delivers the swiftest, simplest action, no matter how low the flow or pressure is. Purging takes place during filling with the integral air vent and so no air can get into the system, meaning it stays the way it is meant to be - closed. An NRV check valve is provided and is located neatly and conveniently, fitted into the fill line just below the durable steel tundish. The entire unit is welded to conform rigidly to BS EN 287 and are designed to PD 5500:2009 category 3 (CE Marked) standard at their respective working pressures, details of which can be found on the product page along with an informative step-by-step usage guide. Make sure that the closed system will offer adequate protection to the dosing pot, keeping it working within its defined limits.

Most system sizes are catered for in our selection of chemical dosing pots, which range from a 3.5 litre capacity to that of our largest model, which is of an industrial 25 litre capacity.
