Closed System Dosing Services

Professional chemical dosing for closed heating and chilled water systems to help control corrosion, scale and microbiological activity and maintain effective system protection.

Closed System Chemical Dosing

Maintaining the correct chemical treatment levels is important for protecting closed heating and chilled water systems against corrosion, scale and microbiological activity. Over time, treatment concentrations can fall due to water loss, system alterations, maintenance or the introduction of untreated make-up water.

BrodexTrident provides closed system dosing services to restore or maintain appropriate treatment levels within the system. Where required, dosing can be carried out following closed system water sampling and analysis, allowing the treatment requirements to be based on the condition of the system water and existing chemical concentrations.

Our engineers can dose systems with appropriate treatment chemicals to help protect pipework and system components, maintain water quality and support reliable, efficient operation.

You may need closed system dosing if:

  • Closed system sampling identifies low or inadequate inhibitor levels
  • Water analysis indicates corrosion or poor water quality
  • The system has been drained, flushed or refilled
  • New pipework or components have been added or replaced
  • Significant quantities of fresh make-up water have entered the system
  • Treatment levels need to be restored following remedial works
  • Ongoing monitoring indicates that chemical treatment is no longer within the required range

Why choose BrodexTrident for your closed system dosing?

Experienced water treatment specialists

Our engineers understand the treatment requirements of closed heating and chilled water systems and can provide practical support based on the condition and requirements of the system.

Dosing informed by system condition

Where sampling or analysis results are available, these can be used to help determine the appropriate treatment requirements before dosing is carried out.

Support with testing and treatment

BrodexTrident can provide both closed system sampling and chemical dosing, helping you move from identifying a water quality issue to carrying out the required treatment.

Commercial and multi-site support

We support commercial premises and property portfolios across the UK, providing closed system water treatment services as part of planned maintenance or individual remedial requirements.

What's included in our closed system dosing service?

Review of treatment requirements

We review available water analysis results, system information and identified treatment requirements before dosing is carried out.

Chemical dosing

Appropriate treatment chemicals are introduced into the closed system to establish, restore or adjust treatment concentrations.

Inhibitor level correction

Where inhibitor levels have fallen below the required concentration, additional inhibitor can be dosed to help restore system protection.

Dosing following system works

Treatment can be reinstated following draining, flushing, repairs, component replacement or other works that may have diluted or removed existing chemicals.

Heating and chilled water systems

Chemical dosing can be carried out on closed heating and chilled water systems where treatment is required.

Support with ongoing water treatment

Where appropriate, we can also support with further closed system sampling and analysis to help monitor water quality and treatment levels over time.

Need closed system dosing?

Whether testing has identified low treatment levels, your system has recently undergone works, or you need support maintaining appropriate water treatment, our team can help.
