The Benefits of Side Stream Filtration on LTHW Systems
The Problem
LTHW systems rarely fail because of poor design – they fail because of what happens inside the pipework over time.
Magnetite, corrosion debris and installation residue steadily build up’ leading to: –
– Reduced heat transfer efficiency
– Increased pump wear and failure
– Blocked control valved and strainers
– Rising energy and maintenance costs
Solution
Sidestream Filtration addresses this by continuously removing fine contaminants while the system remains operational – not just at commissioning, but throughout the systems life.
How does Sidestream filtration do this?
– Captures fine particulate (<5 micron) that traditional strainers will pass.
– Reduces ongoing corrosion by limiting debris circulation.
– Maintains cleaner heat exchangers and components.
– Supports stable differential pressures and control performance.
Crucially, most system contamination is generated after handover – making continuous filtration a proactive asset protection measure, not a remedial one.
As energy efficiency, system reliability and lifecycle value become under greater scrutiny, sidestream filtration is becoming less of a “nice to have” and more of a design and operational essential.
