Clean systems at handover.Stable systems for the life of the building.
Poor water quality in heating and cooling circuits costs energy, damages plant and shortens asset life. We clean, monitor and remediate closed systems to BSRIA BG29 and BG50, with chemical free regimes wherever the system allows.

From first fill to remediation.
Pre-commission cleaning
Flushing and cleaning of new systems to BSRIA BG29, including chemical free methods.
Remedial cleaning
Recovery of fouled or corroding systems to BSRIA BG50, CIBSE CP1 and site specific criteria.
Closed system monitoring
Sampling, interpretation and trend reporting for treated and VDI 2035 regimes.
Remote water quality monitoring
Sensor based monitoring of conductivity, pH, oxygen and corrosion rate.
Side stream treatment
Demineralisation, filtration and membrane degassing, supplied and installed.
Dosing and monitoring equipment
Automatic dosing and monitoring equipment for closed systems, supplied, installed and maintained.
District heating
Cleaning and water quality management of heat networks and large primary circuits.
Failure investigation
Root cause investigation of corrosion, deposits and microbiological fouling in closed systems, followed through to remediation.
Fix the cause, then the chemistry.
Investigate
Sample the water and any deposits, and read the results against the system's materials and history.
Control the microbiology
Where bacteria are a factor, we deal with them first with biodispersant, biocide and dedicated filtration.
Demineralise
Side stream demineralisation brings conductivity down, with side stream filtration protecting the resin beds.
Verify and hand back
A defined endpoint for conductivity and pH, recorded as the handover evidence.
The right equipment for the size of the system.
An established supply chain for high flow and high volume pumping, filtration assemblies, demineralisation and membrane degassing plant. We size it to the system, not to what happens to be in the van.
What is the difference between BSRIA BG29 and BG50?
BG29 covers pre-commission cleaning of new pipework systems. BG50 covers water treatment and water quality management for closed heating and cooling systems once they are in use.
How often should a closed system be sampled?
BG50 sets out a risk based approach, typically laboratory sampling every quarter, with more frequent checks for new systems or where results are poor.
Can a system be treated while it stays in service?
In most cases, yes. Side stream filtration, demineralisation and degassing run alongside the live system, so the building keeps its heating or cooling while the water is brought back into control.
Our results show high bacteria or iron. What does that mean?
On their own, very little. Results need reading together, against the system's materials, history and trend. Send them to us and we will tell you what they mean and what, if anything, needs doing.
Results you cannot explain?
Send them to us. One of our engineers will talk you through what they mean.
