Chemical Dosing Pots

SIZING

The size of the dosing pot installed in a system is not critical as multiple doses of chemicals can be put into the system to reach the correct concentration. A smaller unit is easier to handle physically and allows for more accurate dosing. However, the time on site for performing multiple doses has to be considered; this factor should influence your decision when selecting dosing pots.

Note: Chilled water systems often require large volumes of glycol to be dosed into the system; a larger dosing pot may be required for chilled water systems.

The formula below can be used as a guide to help you in your selection:
Boiler power (kW) x 12 litres/kW x 0.01 (based on 1% concentration*) = volume of chemical required

Example: Boiler power 250 kW x 12 litres x 0.01 = 30 litres of chemical.

You could use any of the following dosing pots for this installation:
– 5 litre – dose six times
– 10 litre – dose three times
– 15 litre – dose two times

*Confirm the required concentration level for the chemical being used.
