Scale adhesion
When limescale builds up inside heat exchangers and piping, it reduces heat transfer efficiency, narrows flow paths, and increases the frequency of cleaning.
DEWEHA Frequency Conversion Inductive Water Processor
A physical water treatment solution for circulating cooling systems, without relying on chemicals.
DEWEHA is a water treatment system using frequency conversion induction technology originating from Germany. The document introduces examples of its use in industrial applications for scale adhesion, fungal slime, and corrosion.
ChallengesThree Key Challenges
In cooling water systems, scale, fungal slime, and corrosion affect heat exchange efficiency, maintenance, and operating costs.
fungi algae slime
Biofilm and sticky sludge cause flow path obstruction and increase the burden of water quality management. The material explains the suppression mechanism using electromagnetic fields.
corrosion
Red rust and corrosion products affect pipe life and stable operation. DEWEHA has a mechanism for forming an anti-corrosion film.
ProductProduct
DEWEHA is a physical water treatment device that installs windings in pipes and applies frequency-controlled electric and magnetic fields to water. The document introduces this as a technology that responds to water quality by changing the frequency from 0 to 60kHz.
- Water treatment method that does not rely on chemical injection or water softening
- Assuming installation that reduces operation stoppages
- Maintenance operation with reduced consumables
- Compatible with cooling water, heat exchangers, air conditioning, boiler systems, etc.

germany ford motor vehicleSolving scale problems for the entire production factoryIn 1993, the Ford automobile factory in Germany installed DEWEHA industrial series products in the entire production system, completely solving the problem of water pipe scale throughout the factory. After 8 months of use, the effects were obvious: pipe maintenance and filter usage were halved, and the discharged water did not pollute the environment at all.

The photographic records clearly show the changes in the pipes on the 54th, 34th, and 91st days of use, proving that we can actually achieve the effects of ``descaling, stain prevention, rust removal, and bacteria and algae control'' within the promised period.
