Process Pipework & Heat Transfer

Heat exchanger affected by scale and fouling

Scale and fouling are insulators inside heat exchangers, calorifiers, condensers, cooling circuits and hot water loops.

3mm of limescale on heating surfaces can increase energy demand by approximately 25%, making water-side optimisation a meaningful energy-saving opportunity.

When minerals, sludge or biofouling restrict pipework, pumps have to work harder to maintain flow and pressure.

By supporting cleaner fluid behaviour, by optimising circulation with reduced resistance, we lower the energy required to move water or process fluids around a system.

Fouled pipework and heat-transfer surfaces often drive repeated cleaning, descaling, flushing, filter changes and treatment-product use. Sirona can help reduce the intervention burden by keeping systems cleaner for longer, with case material showing examples such as a 130°C tubular exchanger moving from clogging after 7–8 weeks to no clogging after 25 weeks.

Poor heat transfer and restricted flow can limit how effectively a site uses the equipment it already has. Improving water-side performance can help maintain steadier temperatures, reduce interruptions and support more useful output from existing assets before major capital replacement is considered.

Cooling tower and condenser system for heat rejection

Cooling towers, condensers and chilled-water circuits are highly sensitive to scale, algae, biofilm and fouling. Better water-side behaviour can help cooling systems reject heat more effectively, reduce chemical and maintenance pressure, and support more stable temperature control.

Heat exchangers, condensers, pumps, calorifiers and process pipework are often critical to site performance. Reducing scale, fouling and restriction can help protect these assets, lower avoidable maintenance pressure and reduce the risk of downtime linked to blocked, dirty or underperforming systems.
