Flowdos Chemical Dosing Pot

The flowdos dosing pots are required in order to feed liquid chemicals such as corrosion inhibitors into closed systems. The dosing pots consist of a stainless steel vessel with inlet (return) and outlet (flow) valves, a drain valve and a filling valve, a stainless steel tundish, air release valve, wall mounting brackets and a non-return valve.
Closed re-circulating water systems (chilled or hot water) can be dosed on a regular or manual basis by use of these dosing pots. Fitted across flow and return lines, they provide a means to annex a portion of the system water which can be drained away and replaced with the chemical to be dosed. When re-connected to the system, the chemical is flushed through.
The dosing pots are fitted with large 1″ valves, which ensure quick and easy action of the pot even in low flow/pressure conditions. An air vent valve enables the pot to be purged during filling thus eliminating undesirable air ingress to the system. A NRV check valve is fitted into the fill line below the tundish.
It is important that the dosing pots are fitted correctly in to the system to allow rapid chemical feed.
This is best achieved by connecting across the main flow and return pipe work. Ideally the flow connection should be made on to the bottom of the dosing pot and the return the top.
