Why Regular Maintenance of Heat Exchangers is Essential

The photo shows the inside of a multi-element heat exchanger. These units play a vital role in transferring heat efficiently across industrial, agricultural, and water treatment systems. However, when groundwater containing iron bacteria passes through them, problems can quickly arise.

The Impact of Iron Bacteria

Iron bacteria thrive in oxygen-rich environments where iron is present. As they grow, they produce slimy deposits and iron oxide build-up that cling to surfaces. Inside a heat exchanger, these deposits:

• Reduce Heat Transfer Efficiency – The build-up forms an insulating layer, forcing the system to work harder to maintain performance.

• Increase Energy Costs – As efficiency drops, more energy is consumed to achieve the same output.

• Accelerate Wear and Tear – Deposits place stress on pumps and other system components, increasing the risk of breakdowns.

• Cause Flow Blockages – Narrowing of the heat exchanger’s channels disrupts water circulation and reduces effectiveness.

Why Regular Inspection and Maintenance Matters

Without intervention, iron bacteria growth can turn a highly efficient heat exchanger into a costly bottleneck. Regular inspection and cleaning prevent build-up before it becomes severe, ensuring:

• Consistent system performance

• Reduced energy consumption

• Longer equipment lifespan

• Fewer unplanned shutdowns

The Solution

Routine maintenance using approved cleaning solutions such as BoreSaver Ultra C and modern rehabilitation practices restores heat exchangers to optimal condition. Preventative treatment also helps to slow down bacterial growth, keeping systems running reliably.
