How to use these guides
The guides are written for procurement teams, plant engineers and business owners who need to buy with confidence without being specialists in every product. They are deliberately practical: each one ends in a checklist you can adapt for your own request for quotation.
Figures in the guides are widely used rules of thumb, not design values. Water chemistry, site conditions and local regulations vary, so always confirm specifications against the supplier's own data and, for anything safety- or compliance-critical, with a qualified engineer.
If you spot something that is wrong or out of date, please tell us. We review and date every guide.
