LTHW & CHW testing and dosing

Keep treatment connected to the test results.

A heating or chilled-water circuit can have an existing treatment programme, a new maintenance requirement or results that need follow-up. AP Environmental provides testing and dosing on both LTHW and CHW systems. The useful starting point is the circuit itself: what it serves, how it has been treated and what has prompted the enquiry.

What we can help with

• Testing enquiries for heating and chilled-water systems
• Review of supplied results and treatment history when scoping work
• Chemical dosing requirements for the relevant circuit
• Discussion of repeat visits and follow-up testing

When to get in touch

For planned maintenance, a change in treatment arrangements, recent system works or a concern raised in water test results. Tell us about recent drain-downs, top-ups or changes to the installation if known.

Agreeing the scope

Define which circuits need testing, what dosing work is required and how follow-up will be handled. Keep closed-system testing separate from Legionella sampling of hot and cold water services.

Helpful information to have ready

• The latest test results, with sample dates and locations
• Current chemical products and previous dosing records
• Circuit volume or drawings, where available
• Site access and any existing maintenance schedule

You can enquire before you have every detail. Start with the information available and we can discuss what else is needed.
