Cooling towers continuously evaporate water to remove heat, leaving dissolved minerals such as calcium and magnesium behind. As these minerals become more concentrated, they form hard scale on heat exchangers, condenser tubes, cooling tower fill and pipelines. At the same time, the warm recirculating water encourages biofilm, algae and microbiological growth, all of which reduce heat transfer efficiency and increase operating costs.
HydroPulse is a chemical-free electronic water conditioning system that treats water without adding chemicals, salt or filters. Using advanced electronic water conditioning technology, HydroPulse changes the crystallisation behaviour of hardness minerals, helping them remain suspended in water instead of sticking to equipment surfaces. Existing scale gradually softens over time while biofilm finds it more difficult to establish, helping maintain cleaner cooling systems, improve efficiency and reduce maintenance.
Without active descaling, mineral and microbiological accumulations degrade system performance rapidly.
As water evaporates, dissolved minerals become concentrated and eventually deposit as hard limescale on heat exchangers, condenser tubes, cooling tower fill and pipelines. Even a thin layer of scale significantly reduces heat transfer efficiency and increases energy consumption.
Warm recirculating water creates ideal conditions for bacteria, algae and biofilm growth. Biofilm restricts water flow, reduces cooling efficiency and provides a protective environment for microorganisms.
Scale deposits and microbiological activity create conditions that accelerate corrosion within the cooling system. Corrosion damages pipes, condensers and heat exchangers, reducing equipment life and increasing maintenance costs.
To maintain acceptable water quality, cooling towers require regular blowdown to remove concentrated dissolved solids. Excessive blowdown increases make-up water demand, wastewater generation and operating costs.

Find answers to technical questions about HydroPulse application on cooling towers.
HydroPulse is a chemical-free electronic water conditioning system that transmits a controlled electrical signal into the water. This signal changes the crystallisation behaviour of hardness minerals, helping prevent scale formation while reducing biofilm buildup throughout the cooling system.
Yes. Existing scale gradually softens and detaches during normal system operation, helping restore heat transfer efficiency without aggressive chemical cleaning.
Yes. By enabling higher Cycles of Concentration (CoC), HydroPulse can reduce blowdown frequency, lowering make-up water requirements and overall water consumption.
HydroPulse can significantly reduce the requirement for anti-scalants and may reduce biocide consumption depending on water quality, system design and operating conditions. Existing water treatment programmes should always be reviewed based on site requirements.
No. HydroPulse has no moving parts, consumables or filters and requires nearly no routine maintenance after installation.
Yes. HydroPulse is externally clamped onto the pipeline, requiring no pipe cutting or major modifications. It can be installed on both new and existing cooling tower systems with minimal disruption.
Our team of engineers customizes systems based on pipe sizes, cycles of concentration, and local water hardness.
