The specific size of the dosing pot is not essential as it only determines the number of times the pot has to be filled to get the correct concentration of dosing chemicals into the system.
The concentration of the dosing chemical varies between one and four per cent, depending on type and manufacturer.
The required volume of dosing chemicals can be calculated as follows:
Volume of Dosing Chemical = Boiler Power (kW) x 12 litres/kW x 0.01 (based on 1% concentration)
Boiler Power 250 kW x 12 litres/kW x 0.01 = 30 litres of chemical dose.
Using a six litre dosing pot filled five times will give the required 30 litres of dosing chemical.
This method of filling a smaller unit multiple times gives a more accurate and easily manageable dosing of the system.
This is approximate guide to sizing of Dosing Pots.
Customer needs to advise the Total System Volume of Water in Litres and then choose from the list below.
Up to 1,000 - 3.5 litre
1,000 to 5,000 - 5 to 6 litre
5,000 to 10,000 - 10 to 11 litre
10,000 to 15,000 - 13.5 to 15 litre
15,000 to 20,000 - 16 to 18 litre
20,000 to 25,000 - 20 litre
Above 25,000 - 25 litre
Water meter proportional dosing is a very efficient way to accurately dose systems and is widely used. HydroChem have many easily installed units being controlled this way, effectively and economically. Chemical feeders ( Chlorine and Bromine) are also available to be an adjunct to manual dosing equipment such as Dosing pots.
The range of Dosing Equipment covers but is not limited to :-
CHEMICAL DOSING METERING PUMPS
CHEMICAL DOSING CONTROLLERS
INSTRUMENTS ( Test kits to calibrate)
CHEMICAL MIXING TANKS AND SAFETY BUNDS
CHEMICAL DOSING POTS
ACCESSORIES (Spares for THROUGH LIFE SUPPORT)
Chemical Dosing units are carefully designed for ease of use for the process desired and each system is tailored by HydroChem technical staff to meet its desired use.
